Abstract
In order to transmit a torque from a hub(rotating body) integrally formed together with a pulleyto, for example, a sleeveinserted under pressure into a rotating shaftof a refrigerant compressor, end surfacesand, which act as a bearing surface, are brought into frictional contact with each other. An axial pressing force is generated by the engagement of screwsandof the rotating shaftand the hub. An annular cut-out part, etc., is provided to form an annular spacein a part of the bearing surface around the rotating shaft. Thereby, the equivalent diameter of the bearing surface is increased, a slip is more unlikely to occur on the bearing surface, and it is therefore no longer necessary to apply an excessive pressing force to obtain a large friction torque.
