であるから、車体のアッパーバー取付部はこの大荷重を
受は得る強度、剛性が必要である。Conventionally, in a vehicle equipped with a body made of synthetic resin such as fiber-reinforced resin (hereinafter referred to as FRP), when an engine and accessories such as a muffler and an air cleaner are attached to the rear of the body, a subframe is attached to the body, The applicant has proposed a system in which an engine, etc. is mounted on the subframe (Utility Application 1512-1982)
1), and this time, the same applicant has a similar idea, but due to the layout, large f
In order to maintain the inertia force during f1ffl, sudden starts, and sudden stops, we are considering a structure in which the vehicle body and the upper part of the subframe are connected by a reinforcing member called an upper bar. Since this upper bar bears a large load as mentioned above, the upper bar mounting portion of the vehicle body needs to have the strength and rigidity to bear this large load.

、肉厚増により車体重量が増すとともに原料費が増大し
たり、補強構造により製造工数が増大したりしてコスト
が上昇する問題がある。However, since the basic strength of a synthetic resin car body □ is lower than that of a sheet metal car body, in order to ensure the necessary strength and rigidity at the upper bar attachment part of the car body, the -i method is used. It is conceivable to increase the wall thickness or add reinforcement to a certain attachment part, but this would increase the weight of the vehicle due to the increased wall thickness and increase the cost of raw materials, and the reinforcing structure would increase manufacturing man-hours. There is a problem that the cost increases.

にある。An object of the present invention is to solve the above-mentioned problems and provide a synthetic resin car body that can secure the necessary car body strength and rigidity at the upper bar attachment part without increasing the plate thickness or complicating the reinforcement structure. The object of the present invention is to provide a frame mounting structure for a vehicle.

強部材により連結したことを特徴としている。The present invention provides a vehicle equipped with a synthetic resin vehicle body having an upright wall on the periphery of the floor and a rear seat integrally formed at the rear. The present invention is characterized in that a mounting portion is formed, and the lower surface of the mounting portion and the subframe are connected by a reinforcing member.

な取付部の車体強度、剛性を確保できる。In the frame mounting structure according to the present invention, the reinforcing member is attached to the lower surface of the concave mounting part, and the rigidity of this mounting part itself is improved by making it concave, and the load from the reinforcing member is Since the load is transmitted to the mounting part in the direction along the lower surface thereof, the load bearing force is greatly improved. In other words, since the load is transmitted in the mounting direction, the component of the bending force that acts perpendicularly to the mounting surface is small, meaning that the load is released along the mounting surface. The vehicle body strength and rigidity necessary for bearing the load from the reinforcing member can be secured without increasing the thickness or requiring a complicated reinforcing structure.
