Abstract
Provided is a scroll compressor, etc., having high performance and reliability. The scroll compressor comprises a closed container, a fixed scroll (22), an orbiting scroll (23), a frame (21), an electric motor, and a shaft (3). Furthermore, the scroll compressor comprises a main bearing (11) installed in a shaft insertion hole (hf), an orbiting bearing (12) installed on an orbiting shaft (23c), a slide bush (13) installed in an eccentric hole (he) on the radially outer side of the orbiting bearing (12), and a ring (14) that closes an annular gap (g1) between an upper-end part (3b) of the shaft (3) and the slide bush (13) from above. Axial-direction installation areas (Q1, Q2) of the main bearing (11) and the orbiting bearing (12) overlap at least partially.IPC Classes ?
