Abstract

A vehicle door structure includes a door sash part and a sash retainer. A paint sealer is applied to a periphery of a vehicle lower side of the sash retainer continuously without a gap from an inner side to an outer side in a vehicle width direction through a vehicle lower portion so as to close a space between the sash retainer and the door sash part. The door sash part has a region that is lower than an application upper end of the paint sealer, that has both sides in the vehicle width direction and a vehicle lower side that are surrounded by the paint sealer, that is disposed in surface-to-surface contact with the sash retainer. A drain hole configured to drain liquid is provided on the region.

1 . A vehicle door structure comprising: a door sash part provided to surround a door window unit in a vehicle upper portion of a door of a vehicle; and a sash retainer extending in a vehicle upper-lower direction and a vehicle width direction of the vehicle, the sash retainer being fixed to the door sash part and having a surface that contacts with a surface of the door sash part, the sash retainer being configured to hold a weather strip part that prevents liquid from entering an inside of the vehicle more than the vehicle door from an outside of the vehicle in the vehicle width direction, wherein a paint sealer is applied to a periphery of a vehicle lower side of the sash retainer continuously without a gap from an inner side of the periphery in the vehicle width direction to an outer side of the periphery in the vehicle width direction through a vehicle lower portion of the periphery in such a manner as to close a space between the sash retainer and the door sash part, the door sash part has a region that is lower than an application upper end of the paint sealer, the region having both sides in the vehicle width direction and a vehicle lower side that are surrounded by the paint sealer, the region being disposed in surface-to-surface contact with the sash retainer, and a drain hole configured to drain liquid is provided on the region.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application claims priority from Japanese Patent Application No. 2022-195954 filed on Dec. 7, 2022, the entire contents of which are hereby incorporated by reference. BACKGROUND The disclosure relates to a vehicle door structure. In general, a door with a sash in which a sash surrounding a door glass is attached to a vehicle upper portion of a door body in which a door outer panel and a door inner panel are joined is widely used as a vehicle door. In this type of door, a weather strip or the like is attached between the sash and the vehicle body in order to prevent entry of rainwater or the like from the outside when the door is closed. The weather strip is in close contact with the space between the sash and the vehicle body to prevent intrusion of water droplets or the like from the outside. Further, the sash is formed by joining a sash outer and a sash inner, and a glass run attachment channel to which a glass run that slidably guides a door glass is attached, a weather strip attachment channel (retainer) to which a weather strip is attached, or the like is integrally formed with or joined to the sash. By the way, since the sash outer and the sash inner are joined to each other, dew condensation generated by a change in air temperature or the like, water droplets or the like entering from a connecting portion or the like may stay in a hollow portion formed in the inside surrounded by the sash outer and the sash inner. Accordingly, there is a possibility that rust is generated inside the sash and moisture containing rust leaks out from the inside of the sash and stains an external appearance surface of a vehicle body or the like. For this reason, for example, Japanese Unexamined Patent Application Publication (JP-A) No. 2000-108664) discloses a technology having a front sash and a rear sash in which a sash outer panel and a sash inner panel are overlapped with each other, and a lower part in a hollow cross-sectional part S formed by a sash outer and a sash inner communicates with the inside of the door body via a communication passage to thereby discharge moisture so that dew condensation or water or the like having entered the inside of the sash is quickly discharged without staying therein, and rusting in the sash is suppressed (see, for example, JP-A No. 2000-108664). SUMMARY An aspect of the disclosure provides a vehicle door structure. The vehicle door structure includes a door sash part and a sash retainer. The door sash part is provided to surround a door window unit in a vehicle upper portion of a door of a vehicle. The sash retainer extends in a vehicle upper-lower direction and a vehicle width direction of the vehicle. The sash retainer is fixed to the door sash part and has a surface that contacts with a surface of the door sash part. The sash retainer is configured to hold a weather strip part that prevents liquid from entering an inside of the vehicle more than the vehicle door from an outside of the vehicle in the vehicle width direction. A paint sealer is applied to a periphery of a vehicle lower side of the sash retainer continuously without a gap from an inner side of the periphery in the vehicle width direction to an outer side of the periphery in the vehicle width direction through a vehicle lower portion of the periphery in such a manner as to close a space between the sash retainer and the door sash part. The door sash part has a region that is lower than an application upper end of the paint sealer, that has both sides in the vehicle width direction and a vehicle lower side that are surrounded by the paint sealer, that is disposed in surface-to-surface contact with the sash retainer. A drain hole is configured to drain liquid is provided on the region. BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings are included to provide a further understanding of the disclosure and are incorporated in and constitute a part of this specification. The drawings illustrate an embodiment and, together with the specification, serve to describe the principles of the disclosure. FIG. 1 is a schematic configuration view of a vehicle door according to an embodiment of the disclosure as viewed from outside in a vehicle width direction; FIG. 2 is an enlarged perspective view of an RT part illustrated in FIG. 1 as viewed from inside in a vehicle rear and vehicle width direction; FIG. 3 is a cross-sectional view taken along line A-A illustrated in FIG. 2; and FIG. 4 is a perspective view illustrating a flow of a water droplet in an RT part illustrated in FIG. 2 as viewed from inside in a vehicle rear and vehicle width direction. DETAILED DESCRIPTION The technology described in JP-A No. 2000-108664 has a problem that a discharge path is not secured for moisture or the like that has entered between plates of a sash outer and a sash inner, a weather strip attachment channel (retainer), or the like, and when a lower end of a joint in a lower part of th
