To attach an electrical equipment cover with one operation, improve workability, and reduced its cost, and prevent vibration from causing backlash noise, by providing a bracket with a plurality of locking parts and fixing the electrical equipment cover with a snap to the bracket using the locking parts as fulcrums.

Locking parts 12 of a bracket 11 are locked with locking holes 17 in an electrical equipment cover 16, and the cover is fixed to a snap hole 14 of the bracket 11 with a snap 18 using the locking parts 12 as fulcrums. A protrusion 19 is structured to eliminate a gap between the bracket 11 and the electrical equipment cover 16 in the condition that the cover 16 is fixed with the snap, and to slightly press the gap with elasticity of a resin-made cover 16. A contact projecting surface 20 is brought into contact with a compressor 1 and is welded resistantly with three welding protrusions. The contact projecting surface 20 perfectly surrounds a glass terminal 2 and completely shields a water drop. By this structure, attachment can be effected with one operation, and by the elimination of the gap the backlash noise can be prevented.
