摘要： A power transmission device according to this invention includes a rotatably supported pulley (6), an elastic member (21) overlapped on the pulley from one side in the axial direction of a rotating shaft, a fixing screw (11) extending through the pulley and the elastic member in the axial direction, a nut (24) sandwiching the pulley and the elastic member in cooperation with the fixing screw, an annular nut holder (25) for holding the nut, and a latching structure (27) for attaching the nut holder to the pulley. The latching structure includes a plurality of hook through holes (14) extending through the pulley in the axial direction, and a plurality of hooks (13) projecting from portions of the nut holder, the portions corresponding to the hook through holes. The hook through holes and the hooks are spaced apart from each other along the rotational direction of the pulley. The hook has a latching piece (36) which comes in contact with the pulley from a side opposite from the nut holder, when the position of the nut holder in the rotational direction with respect to the pulley is changed while the hook is inserted into the hook through hole.

摘要： A power transmission device includes a pulley (4) and a hub (11) that are arranged on the same rotation axis, and a connecting member (13) that connects these rotation bodies. The power transmission device includes a first connecting structure (14) that connects one end portion (13a) of the connecting member to the pulley so that one end portion (13a) cannot be separated, and a second connecting structure (15) that connects the other end portion (13b) of the connecting member to the hub so that the other end portion (13b) can be separated. The second connecting structure includes a columnar body (21) that extends through the other end portion (13b) of the connecting member (13) in the axial direction, a head portion (28) that is provided on the columnar body (21), a slit (22) of the connecting member (13), and a belleville spring (29) that presses the connecting member (13) against the rotation body. The other end portion (13b) of the connecting member (13) is formed to be larger than the remaining portion of the connecting member (13) when viewed from the axial direction. A recessed portion (16) that is recessed toward the outer peripheral side of the hub (11) is formed at a portion of the other end portion (13b) that is directed to the shaft center side of the hub (11). The power transmission device capable of setting with high accuracy the operation load of a torque limiter that cuts off power transmission can be provided.

摘要： An electromagnetic clutch includes an armature to be attracted to a rotor, an armature hub formed on one end portion of a rotating shaft, and a leaf spring which connects the armature to the armature hub and biases the armature away from the rotor. The leaf spring includes a base fixed to the armature hub, a stopper connected to the base, and a connecting piece surrounding the stopper by projecting outside from the base, and fixed to the armature. A through hole into which a rivet for fixing the base to the armature hub is inserted is formed in the base. A low-strength portion having strength lower than that in the periphery of the through hole is formed in a boundary portion between the base and a connecting portion.

摘要： An electromagnetic clutch includes a rotation transmission member supported by an input shaft portion via a bearing. The rotation transmission member includes a movement regulating portion having abutment portions that abut against the bearing. The clutch further includes first and second spring members that bias an armature toward a braking member, and a connecting member overlaid on the movement regulating portion. The connecting member has first holes at portions facing the abutment portions, and second holes at portions facing regions between the abutment portions. One-end portions of the first and second spring members are attached to the armature. First fixing members inserted into the first holes fix the other-end portions of the first spring members to the connecting member. Second fixing members inserted into the second holes fix the other-end portions of the second spring members to the connecting member and fix the connecting member to the movement regulating portion.
