Zusammenfassung:	PURPOSE: To provide a scroll compressor without a trouble due to a structure of a bleeding hole communicating with a scroll compression chamber and a scroll back pressure chamber. CONSTITUTION: A fixed scroll 2 having a fixed volute tooth 4 and a swivel scroll 9 provided with a swivel volute tooth 12 engaged with the fixed volute tooth 4 to form a compression chamber 11 to be swiveled against the fixed scroll 2 are provided in a closed vessel 1. A screw bar unit having a fine through hole is fitted in a tightening condition by screwing to one of the fixed scroll 2 and the swivel scroll 9, to form a bleeding hole 25 of communicating with a back pressure chamber 23 and the compression chamber 11. In this way, at abnormal pressure rise time of the compression chamber when operated a scroll compressor, the screw bar unit is prevented from coming off. Accordingly, a trouble by the screw bar unit coming off is prevented to improve operation reliability.
