Abstract

A rotary machine having a machine body and a cover covering an opening of the body. The cover is fixed to the body by an improved vibration-absorbent structure. A peripheral edge of the cover which is adjacent to the body has plate-spring-shaped mounting brackets whose distal ends project from the edge. The end of the machine body which is adjacent to the cover has mounting portions that are grooves or holes. The bracket distal ends are inserted into the mounting portions through rubber vibration insulating members. With the structure, the cover is assembled at improved efficiency and is restrained from vibration.
