Abstract: A vehicle door body outer panel includes a lower frame arranged in a lower portion of the door body, extending in the longitudinal direction of the vehicle, an outside plate forming a surface of the vehicle body outside the lower frame, and an inside plate folded back at a lower end portion of the outside plate, extending to the inside of the lower frame. When the lower frame and the outer panel are joined to each other, a closed cross section is formed in the lower portion of the door body.

Abstract: A vehicle door outer panel formed through a gas assist injection molding method has a panel main body and an elongated hollow reinforcement projection on an inner surface of the panel main body and extending in a longitudinal direction of a vehicle body so as to oppose a side sill of a vehicle body frame. Accordingly, it is possible to absorb a collision load from a side of a vehicle body by allowing the collision load to be transmitted to the vehicle body frame.

Abstract: A structure for detachably attaching a wheel housing cover to a vehicle body. Provided along the reverse side of a wheel house cover (2) on a peripheral edge are engagement parts (2E, 2F) having upwardly opened engagement holes (2E1, 2F1). In the vicinity of a lower part of the wheel house cover (2)are an insertion hole (2J1, 2K1) for a stud fastener at a front edge rib (2B) and a rear edge rib (2C). A vehicle body is provided with locking parts relatively and downwardly inserted into the corresponding engagement holes (2E1, 2F1) so as to lock said engagement parts (2E, 2F), and is further provided with nut members of receiving parts for receiving the stud fastener.

Abstract: A method for joining frame members, wherein frame members are joined without forming the intricate configuration on the end part of the frame members, and without using the joining members.

Abstract: A combined processing apparatus includes a punching mechanism having a punch or a drill for punching in a hollow material, and a bending mechanism for bending the hollow material. A core bar is inserted into the hollow material. The core bar is provided with a recess portion in correspondence to a position of the punch or the drill, which serves as a die upon punching a hole in the hollow material.

Abstract: The present invention is constructed so that, in a structure for fitting a door molding which is provided for covering a gap between a door outer panel and a window glass, the door molding is fitted on an upper portion of the door outer panel by a thermosetting structural adhesive material. The door molding can be simply fitted on the door outer panel only by heating the thermosetting structural adhesive material. Moreover, after fitting, a firm fitting state can be maintained by the thermosetting structural adhesive material.
