Claim Text:
1. Rotary machinery with a one-way clutch integrated pulley, comprising: a housing; a rotating shaft that is supported inside the housing by way of a support bearing so as to be able to rotate freely; a sleeve that is fastened to a portion of an end section of the rotating shaft that protrudes outside the housing; a pulley that is arranged so as to surround the sleeve and so as to be concentric with the sleeve; a one-way clutch that is provided between the outer circumferential surface of the sleeve and the inner circumferential surface of the pulley, and that allows torque to be transmitted between the pulley and the sleeve only when the pulley has a tendency to rotate in a specified direction relative to the sleeve; a pair of support bearings that are provided on both sides of the one-way clutch, and between the outer circumferential surface of the sleeve and the inner circumferential surface of the pulley, and that allow relative rotation of the pulley and the sleeve, while at the same time supports radial loads that are applied to the pulley; and a spacer that is provided between the support bearing for the rotating shaft and the sleeve, and that is for positioning the sleeve in the axial direction with respect to the rotating shaft, wherein a small-diameter section is provided on the spacer, and that small-diameter section is press fitted into the inner-diameter side of one end section of the sleeve.
