Description

Opening and Closing Structure for Tonneau Cover of Pick-Up Truck The present invention relates to a toner cover opening and closing structure for a pickup truck, and more specifically, to a toner cover opening and closing structure for a pickup truck that increases the space utilization of the cargo space and significantly reduces noise during sliding movement. Generally, a pickup truck's cargo space is formed by side parts provided on the left and right sides of the rear of the vehicle body, a tailgate part provided at the rear of the vehicle body, and a floor part defining the floor surface. In this case, items are loaded into the cargo space of the pickup truck, and the top is opened or closed with a cover or a tonnage cover. At this time, the toner cover is typically installed on one side of the pickup truck's cargo space and configured to allow the toner cover to be wound or extracted on a winding shaft inside the housing. However, conventional pickup trucks had the problem that the housing including the winding shaft occupied a significant volume in the longitudinal structure of the cargo space, thereby reducing the usability of the cargo space; there was also the problem of noise caused by friction with the guide rail when the toner cover was guided by the guide rail; and there was the problem of significantly reduced operability when foreign matter was present on the guide rail. Conventional technology refers to technical information that the inventor possessed for the derivation of the present invention or acquired during the process of deriving the present invention, and it cannot necessarily be considered publicly known technology disclosed to the general public prior to the filing of the present invention.
