Normally, when electrical and electronic equipment is stored in a storage box, the electrical and electronic equipment is supported by a mounting angle and is stored at a required position in the storage box by adjusting the mounting position and mounting direction of the mount angle. You. The mount angle is used not only as an adjustment member for the storage position, but also for storing electrical and electronic equipment configured with dimensions based on other standards in a storage box configured with dimensions based on a certain standard. It is also widely used as an intermediary member. The mount angle is movably mounted in the storage box in order to store electrical and electronic devices and the like configured in various sizes and shapes at required positions in the storage box.
[0003]
Conventionally, as a mounting structure of a mount angle movably mounted in a storage box, as shown in FIG. 4, a mounting member 120 such as a stud bolt is fixed in a storage box 112 by a fixing means such as welding or caulking.

The electronic device 10 is supported by the mount angle 1.
[0009]
The storage box 12 is formed in a dimensional shape corresponding to, for example, a 19-inch rack standardized by EIA. The base 11 of the storage box 12 has two parallel second mounting rails 20 and 20 formed by bending the left and right sides of the back side inward so as to extend in the vertical direction so as to extend in the same width band. It is arranged. In each of the second mounting rail portions 20, a plurality of rail mounting holes 21 for mounting both end portions of the first mounting rail portion 15 are vertically provided at the same pitch T2. A female screw is engraved on the inner peripheral surface of each rail mounting hole 21.
