Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial field of application The present invention relates to a fixture for attaching parts and the like to the body of an automobile.

2. Description of the Related Art It is common practice to mount various parts and the like on a support, form parts-fixing members for each, and mount and fit these parts to fix the parts. Among them, for example, when fixing parts and the like to a vehicle body when assembling an automobile, a bracket b having a hole a for locking a part of the vehicle body is formed as shown in FIGS. On the other hand, an elastic arm e having an engaging claw f is formed on a frame-shaped fixing part d provided on the side surface of the component c, and the bracket b is inserted into the fixing part d so that the locking hole a and the engaging claw are formed. Methods such as engaging with and were used.

Problems to be Solved In such a conventional component fixture, the bracket b
In order to facilitate the work of fitting the fixing portion d, it is necessary to form the insertion window of the fixing portion larger than the size of the bracket. In this case, since there is a gap between the bracket and the insertion window, there is a problem that abnormal noise is generated due to the vibration of the vehicle body.

Furthermore, such a bracket needs to be accurately formed at a specific position on the vehicle body, which makes it difficult to change the component mounting position.

Therefore, the present invention intends to provide a component fixing tool which can fix components tightly without rattling and can easily change the mounting position.

[Constitution of device]

Means for Solving the Problems The above-mentioned object of the present invention is to provide a support body having a locking hole provided behind a fold line of a plate-like member having a tip portion formed by bending the cross-section into an L shape. On the other hand, a base part that can come into contact with the back surface of the tip part and an elastic arm that is erected from one end of the base part and that can press the back surface of the plate-like member and can fit into the locking hole Mounting and fitting a fixing structure having an engaging portion and a locking protrusion that is erected from the other end of the base portion to face the elastic arm and that can lock the edge of the tip end portion. This can be achieved by the connecting structure of the component fixing device.

Action In the component fixture of the present invention having the above-mentioned structure, the elastic arm constantly presses the back surface of the plate-shaped member, so that there is no play even after the fitting.

EXAMPLE The structure of the component fixture of the present invention will be described with reference to the examples of FIGS.

Reference numeral 1 is a support body having an L-shaped bent portion 11 at an end portion of a steel plate constituting a vehicle body of an automobile, and a locking hole 12 is provided therein. Reference numeral 2 denotes a component fixed to the support 1, such as a protector for a wire harness, and a fixing structure 3 is formed on one side thereof. When the component 2 is made of, for example, hard plastic, the component 2 and the fixing structure 3 may be integrally formed. When the fixing structure 3 is formed separately, the fixing structure 3 may be separately fixed to the component 2 by appropriate means, and at this time, respective constituent materials may be the same or different.

The fixing structure 3 includes the elastic arm 32 with the base end 31 interposed therebetween.
And the pressing portion 33 are erected so as to face each other, and are configured in a U shape as a whole. An engaging protrusion 34 that can engage with the locking hole 12 is formed on the abdominal surface of the elastic arm 32, and an engaging protrusion 35 that can engage with the tip edge 13 of the support 1 is formed on the abdominal surface of the restraining portion 33. There is.

When such a fixing structure 3 is inserted and fitted into the support 1, the tip edge 13 of the support is locked by the locking projection 35, and the locking hole 12 is locked by the engaging projection 34. At the same time, the back surface of the end portion 11 of the support member is brought into contact with and fixed to the surface of the base portion 31. At this time, since the elastic arm 32 is pressure-bonded to the back surface of the support body 1, there is no play between them.

In addition, the rising wall portion 36 provided on the side edge of the restraining portion 33 abuts the side edge 14 of the support body 1 and functions as a guide member when the fixing structure 3 is fitted to position the fixing tool. Useful to facilitate.

[Effect of device]

Since the component fixing device coupling structure of the present invention can securely fix components without rattling, no abnormal noise is generated by vibration. Further, as long as the end portion of the plate-like support is bent in an L-shape, it can be formed at any place only by providing the locking hole. Therefore, in the case of a vehicle body of an automobile or the like, since the edges of the steel plate members that are formed are bent into an L shape, it is not necessary to form a bracket, and the fixing tool can be attached simply by making a hole, and the work can be performed. It is easy and it is easy to change the attachment position of the fixture.
