[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a clip for fixing a plate-like component such as a trim board of a vehicle to a predetermined panel with a single touch.

[0002]

2. Description of the Related Art As a conventional clip of this type, for example,
There is one disclosed in Japanese Utility Model Publication No. 5-6404. Although not specifically shown, the conventional clip is an integrally molded product of a synthetic resin, and includes a head for holding a plate-like component such as a trim board, and a leg that is engaged with a mounting hole of the panel. The former has a pair of retaining flanges and a sealing flange spaced apart via a neck, and the latter has three elastic locking walls that are flexible in its axial direction. A configuration in which all the locking shoulders for holding the hole edge of the mounting hole of the panel from inside and outside are formed at the same horizontal level on the upper side of the outer peripheral surface of each elastic locking wall in cooperation with the seal flange. Has become.

In actual use, a plate-like component is held between the holding flanges of the head, and in this state, the legs of the clip are inserted into the mounting holes formed in the panel side. Then, each elastic locking wall of the leg portion is bent inward and passes through the inside of the mounting hole to return to its original shape by its elastic force, and at the same time, each locking shoulder is engaged with the hole edge of the mounting hole. As a result, the plate-like component can be easily fixed to the panel side. Therefore, under the conventional clip, the distance between the sealing flange and the locking shoulder formed at the same horizontal level on the outer peripheral surface of each elastic locking wall is limited to
Since the thickness of the panel to which the plate-like component is fixed is automatically determined, if the thickness of the panel matches the above-mentioned interval width, the plate-like component is always securely fixed to the panel side. You can do it.

[0004]

However, since there is considerable variation in the thickness of the panel, especially when the panel has such variation, the thickness of the mounting hole of the panel is particularly large. It cannot be denied that the locking shoulder cannot be securely locked to the edge and the fixing state of the plate-shaped component becomes unstable . It follows, in the conventional clip, that you say that you can not effectively absorb the panel thickness of the variation is, in itself, is a serious problem that can not be overlooked, in addition to this, different thickness I couldn't hope for the panel.

[0005]
