Description

Defrosting structure Technical Field The present invention relates to a structure of a defroster provided in a vehicle. Background In order to prevent fog and the like on a windshield panel, a vehicle has a defroster that blows air in a predetermined direction toward a surface of the windshield panel on a vehicle cabin side. For example, patent document 1 describes a defrosted air outlet arranged along a lower edge of a windshield panel on an upper surface of an instrument panel. On the other hand, in recent years, the number of electric parts provided in the instrument panel has increased, and a wider space is required for disposing the electric parts. If the defrosted air outlet can be made closer to the end of the instrument panel, a space can be ensured in its entirety. In addition, the image of the outlet of the defrosted air is reflected by the windshield panel and enters the line of sight in front of the occupant. If the air outlet can be positioned closer to the front, the position of the image will be closer to the lower edge of the windshield panel, and a good line of sight can be ensured over a wide range. In this way, from the viewpoints of the increase in the number of electric components and the securing of visual observation of the landscape, it is desirable to position the defrosted air outlet in front. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2012-148668 Disclosure of Invention When the defroster air outlet is disposed in the instrument panel, a defroster air outlet member is often prepared separately from the instrument panel member and fitted into the opening of the instrument panel member. The defroster air outlet member is fixed to the instrument panel member by a resin claw or the like. However, considering the strength of the instrument panel and the mounting strength of the defroster air outlet member, the defroster air outlet member is fixed by surrounding the defroster air outlet member with the instrument panel member. Therefore, for example, as shown in fig. 5, a front portion 200A of the instrument panel member 200 is required also on the front side of the defroster air outlet member 300, and there is a limit to the measure of positioning the outlet of the defroster air at the front position. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a defrosting structure capable of arranging a defrosted air outlet in a position close to a windshield panel in front of an instrument panel while ensuring the strength of the instrument panel and the attachment strength of a defroster air outlet member. In order to solve the above problems, the defrosting structure of the present invention comprises a windshield panel disposed in front of a vehicle cabin, an instrument panel extending from the windshield panel toward the rear of the vehicle cabin, a blowout port member disposed in the instrument panel and having an opening portion for blowing defrosting air against the windshield panel, and a tunnel member disposed below the instrument panel and having a path for supplying the defrosting air to the opening portion, wherein the blowout port member has an adjacent portion that forms a front edge of the opening portion and is adjacent to the windshield panel, and a fixing portion that is connected to the adjacent portion, and the fixing portion is fixed to the tunnel member at a position that is more forward than a front end portion of the windshield panel exposed to the vehicle cabin when viewed in a cross section in the front-rear direction. Effects of the invention According to the present invention, the defroster air outlet can be arranged at a position close to the windshield panel on the front end side of the instrument panel while ensuring the strength of the instrument panel and the mounting strength of the defroster air outlet member.
