Pulley assembly for driven shaft

摘要

A pulley assembly for a driven shaft is disclosed. The pulley assembly includes a pulley to which a turning force is transferred from a driving unit; a sleeve fixedly mounted to a casing of the driven unit through which the driven shaft passes with a clearance between an outer periphery of the driven shaft and an inner periphery of the sleeve; a bearing structure for bearing the pulley rotatably about an axis of the driven shaft, the bearing structure being disposed between the pulley and the sleeve; and a torque transferring structure for transferring the turning force transferred to the pulley to the driven shaft, the torque transferring structure being interposed between the pulley and the driven shaft.
