Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening / closing holder for an automobile, which is mainly used for holding a door temporarily assembled in a white body in a predetermined opening / closing position in the process of manufacturing an automobile, and more particularly to a door. At least a pair of opposed sandwiching arms are connected to the base plate to be attached so that they can be opened and closed mutually, and a sandwiching spring that urges them in the closing direction is connected between the two sandwiched arms so that both can be opened and closed as the door is opened and closed. The operating arm, which is pivotally supported by the body so as to be displaced relative to the sandwiching arm, is provided with a sandwiched body movably sandwiched by both sandwiching arms, and at least one of the sandwiching plates holds a predetermined door open / close position. The present invention relates to an improvement in which a holding concave portion with which a held body is engaged is formed.

[0002]

2. Description of the Related Art Such an automobile door open / close holder is already known, as disclosed in, for example, Japanese Utility Model Publication No. 58-54309.

[0003]

By the way, in the conventional door open / close holder, since the object to be clamped is constituted by a single roller pivotally supported by the operating arm, the peripheral surface of the roller has both clamping arms. Therefore, the rollers are pressed against the opposite surfaces at the same time. Therefore, when the sandwiching arm and the operating arm are displaced relative to each other when the door is opened and closed, the rollers hardly rotate and slide on the opposing surfaces of the sandwiching arms, and the roller effect cannot be exhibited. There is a drawback of producing a fricative noise, which resonates with the door and becomes a loud noise, which deteriorates the working environment.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide the above-mentioned vehicle door open / close holder which eliminates the above-mentioned drawbacks.

[0005]

In order to achieve the above object, the present invention is directed to a pair of rollers, which have their peripheral surfaces in contact with each other and whose peripheral surfaces are in contact with each other, and are in rollable contact with one and the other sandwiching arm individually. It is characterized in that both rollers are loosely fitted and supported by a pair of support shafts projecting from the operating arm.
