    摘要: A reverse input blocking clutch has a pressed member having a pressed surface on the inner circumferential surface; an input member having an input-side engaging portion arranged on the inner side in the radial direction of the pressed surface and coaxially arranged with the pressed surface; an output member having an output-side engaging portion arranged further on the inner side in the radial direction than the input-side engaging portion and coaxially arranged with the pressed surface; an engaging element arranged on the inner side in the radial direction of the pressed surface so as to move in a first direction which is a far-near direction with respect to the pressed surface; and an elastic member arranged at a position overlapping the output-side engaging portion with respect to the first direction so as to be elastically stretched between the output-side engaging portion and the engaging element.

    摘要: There is provided a clutch mechanism that allows easy downsizing and produces favorable productivity. Output rotator has on the outer circumferential surface thereof cam surfaces and configured to gradually reduce the space from a housing chamber inner circumferential surface toward one side and recesses adjacent to the one side of the cam surfaces. Input rotator has pressure transmission portions that are fitted with circumferential play to the recesses and are protruded from the insides of the recesses in a centrifugal direction. Engagement pieces are disposed in contact with the cam surfaces and the housing chamber inner circumferential surface. When the input rotator rotates toward the other side relative to the one side, the pressure transmission portions abut against the engagement pieces and then abut against circumferential end surfaces in the recesses to press and move the output rotator.

    摘要: A clutch unit includes a lever-side clutch portion for controlling transmission and interruption of rotational torque to an output side through lever operation, and a brake-side clutch portion for transmitting torque input from the lever-side clutch portion to the output side and for interrupting torque reversely input from the output side. The lever-side clutch portion has an outer centering spring provided between a lever-side outer ring to be rotated through the lever operation and a cover restricted in rotation, for accumulating an elastic force obtained by torque input from the lever-side outer ring and for restoring the lever-side outer ring to a neutral state with the accumulated elastic force through releasing of the torque input from the lever-side outer ring.

    摘要: A rotation transmission device is provided in which a collision sound by an armature and a rotor is less likely to occur, and further the armature is stably attracted to the rotor. A buffer is provided between the armature and the rotor. The buffer is constituted by a metal annulus axially movably supported by the armature, and a rubber annulus configured such that as the armature approaches the rotor, the rubber annulus is axially compressed by the metal annulus and the armature. The rubber annulus has different axial thicknesses at different circumferential locations thereof such that when the degree of axial compression of the rubber annulus is large, the rubber annulus is axially compressed in its longer circumferential area than when the degree of axial compression of the rubber annulus is small.
