ABSTRACT:
In order to transmit a torque from a hub5(rotating body) integrally formed together with a pulley4to, for example, a sleeve6inserted under pressure into a rotating shaft1of a refrigerant compressor2, end surfaces5eand6a, which act as a bearing surface, are brought into frictional contact with each other. An axial pressing force is generated by the engagement of screws1aand5dof the rotating shaft1and the hub5. An annular cut-out part7, etc., is provided to form an annular space10in a part of the bearing surface around the rotating shaft1. 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.
