[0002]

2. Description of the Related Art Conventionally, when a mounting member is mounted by engaging an engaging claw at a mounting position where a hook hole is provided, the mounting member is prevented from dropping from the mounting position. An engaging element is provided which is urged by a spring disposed on the mounted member and is capable of protruding and retracting in a linear direction. Thus, when the attached member is in the engaged state, the engaging element is projected to lock the engagement, and when the engagement is released, the engaging element is moved in the direction of accumulating the repulsive force of the elastic body. The member is removed after the member is immersed.

[0003]

However, in such a case, it is necessary to perform a troublesome operation of attaching and detaching the attached member while pushing and retracting the engaging member against the repulsive force of the spring. . In addition, since the engaging element protrudes and retracts in the linear direction, the operating portion for protruding and retracting the engaging element is provided in a limited space between the member to be attached and the mounting position around the hook hole in the vicinity of the engaging element. And there is also a problem that operability is poor. Furthermore, simply disposing the spring and the engaging element, when the force of immersing and pressing the engaging element is loosened, the repulsive force of the spring is released at a stretch, and the engaging element urged by the force flies. Since a problem of detachment occurs, a special stopper mechanism is required.
In addition, it is necessary to separately provide an engaging recess for engaging with the engaging element on the side of the member to be mounted.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention improves operability with a simple structure, engages an engaging claw with a hook hole, and moves a member to be mounted to a mounting position. At the same time, the engagement of the engaging claw is locked, and at the same time, the lock is released by one touch, and the attached member can be removed.
