PURPOSE: A scroll type compressor has a simple structure including a bearing which supports an orbiting scroll member connected to a rotary shaft, and efficiently lubricates the bearing. CONSTITUTION: A scroll type compressor comprises a housing (11), a fixed scroll member (12), an orbiting scroll member (24), a rotary shaft (14), a driving bushing (20), a plain bearing, a boss (27), a driving device accommodating space, and a compression room (S). The rotary shaft includes an eccentric pin (19) in which the driving bushing is inserted to be rotated. The boss is formed at the orbiting scroll member. The driving bushing is inserted into the boss to be slid. The eccentric pin, the driving bushing, and a bearing (23) are arranged in the driving device accommodating space and an upper space (29) and a lower space (49) are formed by the bearing. The compression room is formed by the fixed scroll member and the orbiting scroll member. Gaps are formed to face the sliding surface of the bearing. A communication path (48) for communicating the compression room and the upper space or the gaps is formed in the orbiting scroll member and is opened towards the bearing.
