Abstract: A compressor according to the present invention comprises a hinge recess formed at a rolling piston and a hinge protrusion formed at a vane to be inserted into the hinge recess. A diameter of the hinge protrusion is greater than an interval between both ends of an opening of the hinge recess. A bearing surface, which comes in contact with an inner circumferential surface of the hinge recess, of an outer circumferential surface of the hinge protrusion, has a circumferential surface below 90° at both sides, respectively, based on a central line in a lengthwise direction of the vane. This structure may facilitate for cutting and grinding the bearing surface so as to reduce a machining cost, and also improve a machining degree and thus stabilize behaviors of the rolling piston and the vane so as to enhance compression efficiency.
