Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automobile door, and more particularly to the structure of a plastic door comprising an inner panel and an outer panel made of plastic material.

(Conventional technology) In general, plastic materials are lighter than metal materials and have advantages such as not rusting, and as plastic technology has improved in recent years, they have improved in strength and appearance compared to metal materials. Nowadays products that are as good as those are being manufactured. Along with this, various parts of automobiles are gradually being made of plastic, and attempts have been made to form automobile doors from plastic materials as a link to this trend. In this case, the main body of the door is constructed by joining an inner panel and an outer panel, both of which are made of plastic material, and if necessary, a metal frame member is provided between the two panels. However, when considering the ease of assembly and maintenance of the window glass stored between the two panels, its opening/closing device configuration, door lock device, etc., the above-mentioned two panels should be connected using screw members such as bolts. It is desirable to do so.

By the way, there is a device disclosed in, for example, Japanese Utility Model Application Publication No. 59-64316, in which an inner panel and an outer panel constituting a door are connected by screw members. As shown in Fig. 9, flanges A1 and B1 protruding toward the inside of the vehicle body are provided on the peripheral edge of the inner panel A and the outer panel B, and the flanges A1 and B1 are overlapped with each other, and at least one of the flanges is sandwiched between the sections. Both flanges A1.8+ are fastened using a U-shaped retainer C and a screw D whose threaded portion is engaged with this retainer C, thereby joining both panels A and B at their peripheral edges. According to this, for example, it becomes possible to assemble the outer panel B after attaching a window glass, a door lock device, a frame member, etc. to the inner panel A, thereby improving the assemblability of the door. Also, if necessary, both panels A,
Since B can be separated, adjustment, repair, etc. can be facilitated. However, according to the conventional configuration shown in FIG. 9, since the screws D for connecting both panels Δ and B are located at the peripheral edges of both panels A and B, when the door E is closed, The weather strip G that seals between the weather strip G and the vehicle body F is disposed on the inside of the vehicle body from the joint by the screw D, as shown by the chain line.In other words, the screw D is placed on the outside of the vehicle body of the weather strip G. to be located,
The screw D gets wet and rusts during rain or car washing.

<Object of the Invention> The present invention relates to a plastic door for an automobile that is constructed by joining an inner panel and an outer panel, both of which are made of plastic materials, and a structure in which the two panels are joined using bolts. In addition to improving the ease of assembling the door and maintaining the window glass and door lock device stored between the two panels, the bolts that connect the two panels are particularly effectively sealed from rainwater, etc. The purpose is to prevent the bolt from rusting.
