Abstract
The rotary shaft of a closed-type electrically driven compressor is rotatably supported by self-aligning bearings. Each bearing has a spherical bearing member, a supporting member and a bushing. The supporting member has a concave spherical inner surface and a cylindrical inner surface. The bushing has a concave spherical inner surface and a cylindrical outer surface and is fitted into a space defined by the cylindrical inner surface of the supporting member. The concave spherical inner surface of the supporting member and that of the bushing movably support the spherical bearing member.
