Abstract

PROBLEM TO BE SOLVED: To provide an inexpensive bracket capable of effectively preventing foreign matters from intruding into a cover of electrical equipment by continuously connecting a cover holder molded by bending a flat plate into a substantially U-shape to dust-proofing back plates oriented toward a compressor body in the bracket having the cover of the electrical equipment fitted therearound. SOLUTION: A bracket, which is fixed to a substantially globular sealed container by welding in such a manner as to surround a glass terminal disposed in a compressor body, is formed into a substantially U shaped by bending its side plates 13b, 13c almost perpendicularly on lines A, B. A part of a bottom plate 13d formed at the bracket is bent on a line C, thereby forming a protecting plate 13e. Dust-proofing back plates 13f, 13g, 13h are bent almost perpendicularly on lines D, E and F, respectively. The bracket can be molded into a substantial case, the dust-proofing back plates 13f, 13g, 13h can almost close a foreign matter intruding path, thus preventing foreign maters from introducing into a cover of electrical equipment even if a clearance is defined between the sealed container and the bracket.
