A compressor provided with a torque limiter constructed such that, in view of possible occurrence of accidental locking of the compressor, in the case where a one-way clutch is used in place of an electromagnetic clutch in order to permit a refrigerant compressor for a vehicle air-conditioning system to be driven by an electric motor instead of an internal combustion engine, when an excessive torque is to be transmitted by the one-way clutch, rollers ride over wedge surfaces and fall into pocket sections, or sprags are reversed to roll-over.
