Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a connector used for connecting two members, and more particularly, to a case where one member is connected to another member at a fixed angle. Even if the angle is changed as necessary, or even if the angle is shifted due to a dimensional error, the two members can be reliably connected. The present invention relates to provision of a coupling tool.

[0002]

2. Description of the Related Art For connection of two members, for example, there is a fixing structure disclosed in Japanese Utility Model Publication No. 59-19640.
This fixing structure includes an axial peg provided on the back surface of the molding, and a pair of stopper pieces provided at the tip of the peg so as to protrude from the tip side toward the back side. . Then, the peg is inserted into a mounting hole provided in the body panel, the tip of the stopper piece is engaged with the hole edge of the mounting hole, and the two members, that is, the molding and the body panel are connected. Have been.

[0003]

However, in such a conventional fixing structure, when two members are connected at a fixed angle, for example, in the above example, the back surface of the connected molding and the body are connected. If the panel surface of the panel is not arranged in parallel, the axis of the peg and the hole axis of the mounting hole will not be located on the same straight line, and the tip of the stopper piece will be positioned at the hole edge of the mounting hole as it is. It cannot be engaged. For this reason, such a conventional fixing structure cannot be used simply when two members are connected at a certain angle.

Here, as a technique for absorbing a dimensional error generated between two connected members by a connecting member, there is a structure disclosed in Japanese Utility Model Publication No. 5-3763, for example. Such a structure includes a first clip and a second clip slidably attached to the first clip. Then, by sliding the second clip fixed to the stud bolt with respect to the first clip fixed to the molding, a dimensional error generated between the stud bolt and the body panel side wall adjacent to the stud bolt is reduced. It is configured such that the molding can be attached to the body panel so as to absorb and absorb the space between the side wall of the body panel and the glass by the molding.

However, in the structure disclosed in Japanese Utility Model Publication No. 5-3763, the first clip can be moved only in a direction in which the first clip approaches the side wall of the body panel. When two members are connected at a certain angle, they cannot be used simply.

Accordingly, the present invention solves the disadvantages of the prior art, and in particular, even when one member is connected to another member at a fixed angle.
In addition, even if this angle is changed as required, or if the angle is misaligned due to a dimensional error or the like, it is possible to provide a connecting tool capable of reliably connecting the two members. With the goal.
