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: The invention relates to a refinement of a spindle drive (1), and to a louvered window or a louvered shutter having a spindle drive for moving louver elements such that applied return forces and return torques can be absorbed better, and in particular without placing a load on the drive motor. For this purpose, the spindle drive (1) has a specially designed return stop mechanism (6) arranged between a drive shaft of a drive motor (3) and a threaded spindle (4).

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 rotation transmission device is configured such that when an electromagnet of an electromagnetic clutch is energized, a control retainer of a two-way clutch is moved in the axial direction, so that the control retainer and a rotary retainer rotate relative to each other in the direction in which the circumferential widths of pockets decrease, thereby disengaging pairs of rollers from an outer ring and an inner ring. A spring holder is provided which is fixed to an input shaft and kept in abutment with an axial end surface of the inner ring to prevent relative rotation between the control retainer and the rotary retainer in the direction in which the circumferential widths of the pockets decrease, from the neutral position of the rollers. The spring holder is prevented from axial movement to prevent untimely engagement of the two-way clutch. The inner ring is integral with the input shaft.

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.
