  Thus, as shown in FIG. 7, when the cover body 5 is attached to the U-shaped bracket 4 attached to the back panel 3, the cover body 5 is inserted into the retaining holes 16 of the arm portions 7 on the bracket 4 side. First, the side latching claw 17 is engaged first, and then, as shown in FIG. 8, the cover body 5 is rotated in the direction of arrow A around the engagement point of the latching hole 16 and the latching claw 17. When the holding part 13 on the cover body 5 side is bent and deformed (mainly the lower engaging claw 15 is bent downward) with respect to the locking piece 12 on the bracket 4 side, the holding part 13 is deformed. When returning from the original state to the original state, the upper and lower constricted portions 11 of the locking piece 12 are engaged by the ribs 14 and the engaging claws 15 so as to be held in the vertical direction without using a fastener such as a retainer. However, the cover body 5 can be easily attached to the bracket 4 alone. To become.

  Moreover, when the gripping portion 13 returned from the deformed state to the original state and engaged so as to grip the constricted portion 11 on the proximal end side of the locking piece 12, it could be reliably engaged by sound or touch. Since it becomes possible to confirm this, an incidental effect that an assembly failure of the cover body 5 with respect to the bracket 4 is prevented in advance is also obtained.

  The engagement between the locking piece 12 and the holding portion 13 provided in this way is most easily released when the cover body 5 side rotates around the locking piece 12 with respect to the bracket 4 side. Is prevented by new engagement by the second engaging means comprising the latching hole 16 and the latching claw 17, and the locking piece 12 on the bracket 4 side and the grip on the cover body 5 side are held. It becomes difficult to disengage from the part 13.

  Further, since the operation hole 18 is provided in the side cover portion 10 of the cover main body 5 at a position close to the locking hole 16, a strip-shaped jig 19 is inserted from the operating hole 18 to form the locking hole. 16 and the latching claw 17 can be disengaged.

  Therefore, according to the above-described embodiment, the cover body 5 can be simply and simply attached to the bracket 4 without using a fastener such as a retainer. It is possible to achieve a significant reduction, and it is possible to reduce the number of parts to achieve a significant cost reduction. Furthermore, it is possible to confirm that the engagement has been ensured by sound and feel. Incorrect assembly of the cover body 5 to the bracket 4 can also be prevented.

  Further, the cover body 5 side is prevented from rotating around the locking piece 12 with respect to the bracket 4 side by a new engagement by the second engagement means comprising the latching hole 16 and the latching claw 17. Therefore, the engagement between the locking piece 12 on the bracket 4 side and the holding portion 13 on the cover main body 5 side can be made difficult to disengage, and a more stable mounting state of the cover main body 5 can be obtained.

  Further, when it becomes necessary to remove the cover body 5 from the bracket 4 for inspection, replacement, repair or the like in the factory, a strip-shaped jig 19 is inserted from the operation hole 18 to thereby insert the retaining hole 16. Since the engagement of the latching claw 17 can be released, the cover main body 5 side is rotated around the locking piece 12 with respect to the bracket 4 side to release the engagement between the locking piece 12 and the holding portion 13. The cover body 5 can be removed without any effort.
