摘要： The outer peripheral portion of a drive shaft has a first restriction surface in an integrated manner. The inner peripheral portion of a boss has a second restriction surface in an integrated manner. The second restriction surface faces the first restriction surface in a radial direction. When the electromagnetic coil is not energized, there is a disconnection distance D between the first friction surface and the second friction surface. The distance between the axis and the outermost periphery of the second friction surface is the clutch radius R. A noise preventing space is provided at a point spaced from the bearing to the front by a beam size L2 between the first restriction surface and the second restriction surface. The size d of the noise preventing space satisfies d

摘要： In order to transmit a torque from a hub 5 (rotating body) integrally formed together with a pulley 4 to, for example, a sleeve 6 inserted under pressure into a rotating shaft 1 of a refrigerant compressor 2, end surfaces 5e and 6a, which act as a bearing surface, are brought into frictional contact with each other. An axial pressing force is generated by the engagement of screws 1a and 5d of the rotating shaft 1 and the hub 5. An annular cut-out part 7, etc., is provided to form an annular space 10 in a part of the bearing surface around the rotating shaft 1. 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.

摘要： When the connecting rod 10 made of material of high strength, the mechanical strength of which is higher than that of the inner hub 22, is incorporated into between the cylindrical boss portion 31 of the inner hub 22 and the compressor shaft 2, an outer diameter of the compressor shaft 2 can be made to be smaller than that of the conventional fastening profile. Even when the outer diameter of the compressor shaft 2 is reduced, it is possible to solve the problem of lack of the mechanical strength of the inner circumferential screw portion 35, 44 and the outer circumferential screw portion 43, 3 with respect to the axial fastening force given to the inner circumferential screw portion 35, 44 and the outer circumferential screw portion 43, 3.
