A hook hook 12 is formed at an upper side of the cover body 11, and the hook cover 12 is fitted into the hook groove 3-1 of the bracket 3 so that the relay cover is closed. The bracket 3 is detachably fixed. In addition, a second screw assembly hole 15 corresponding to the first screw assembly hole 3-2 of the bracket 3 is formed at one side of the cover body 11, and these screw assembly holes 3-2 are formed. The screw 15 (not shown) is fastened to the chuck 15 to further secure the relay cover 10 to the bracket 3.

Meanwhile, a bracket stopper 13, which is supported on the bracket 3 when the relay cover 10 is assembled, protrudes outward from an upper side of the cover main body 11, and a second screw of the cover main body 11. A pair of screw stoppers 14 are formed on both sides of the assembling hole 15.

The screw stopper 14 is for preventing the relay cover 10 from being deformed when the relay cover 10 is fixed by the screw. That is, in general, the bracket 3 is made of metal and the relay cover 10 is made of plastic, etc., the second screw assembly hole 15 and the bracket 3 of the relay cover 10. The first screw assembly hole 3-2 is spaced apart at some interval due to the shape of the relay cover 10. Therefore, when the relay cover 10 and the bracket 3 are fixed by screwing, the relay cover 10 is bent inward to prevent the relay cover 10 from functioning as the relay cover. The stopper 14 serves to prevent deformation of the relay cover as described above.

However, since the conventional hook and screw fastening relay cover as described above includes one bracket stopper 13 and a pair of screw stoppers 14 formed at positions separated from each other, the shape thereof It becomes complicated and large, and therefore, there is a problem that the workability and injection property are not good, and the material cost increases.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and improves the stopper to simultaneously perform the bracket stopping and screw stopping functions, thereby simplifying the shape of the relay cover, and improving the workability and injection properties. The purpose is to provide.
