Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/129518
Kind Code:
A1
Abstract:
This power transmission device is provided with a rotatably supported pulley (6), an elastic member (21) that overlaps the pulley from one side in the axial direction of a rotating shaft, a securing screw (11) that passes through the pulley and the elastic member in the axial direction, a nut (24) that, in collaboration with the securing screw, grips the pulley and the elastic member, a ring-shaped nut holder (25) that retains the nut, and a latching mechanism (27) that attaches the nut holder to the pulley. The latching mechanism comprises a plurality of hook through-holes (14) that pass through the pulley in the axial direction and a plurality of hooks (13) that project from positions on the nut holder corresponding to the hook through-holes. The hook through-holes and the hooks are disposed at intervals from one another in the direction of rotation of the pulley. The hooks include a latching piece (36) that, in a state in which the hooks have been inserted into the hook through-holes, is brought into contact with the pulley from the opposite side from the nut holder due to the changing of the position of the nut holder in the direction of rotation with respect to the pulley.
