摘要： A distance between a rotation center of an input member and a contact portion between an input side engaging portion and an input side engaged portion in a second direction is set to be shorter than a distance between a rotation center of an output member and a contact portion between an output side engaging portion and an output side engaged portion in the second direction. In a locked or semi-locked state, a contact portion between the output side engaging portion and the output side engaged portion is located on the side closer to the rotation center of the output member in a first direction in relation to a virtual line connecting the rotation center of the output member and a contact portion between one pressing surface of the pair of pressing surfaces and the pressed surface.

摘要： In the centrifugal pendulum damper, a plurality of pendulums are swingably supported on a rotating body. The pendulum includes a swinging shaft serving as the swing center and a rolling shaft including a rolling surface on the outer periphery thereof. The rotating body includes a plurality of pendulum support portions, and the pendulum support portion includes a swinging shaft guide portion that guides the swinging shaft in a radial direction of the rotating body, and a rolling shaft guide portion that is in rolling-contact with the rolling surface of the rolling shaft to cause the pendulum to swing around the swing axis.

摘要： Construction is achieved whereby durability is maintained while size and weight are reduced. Installation plate sections are provided on the top and bottom end sections of a pair of support columns. Bolts are inserted through through-holes that penetrate through the installation plate sections in the axial direction; the bolts are then screwed into screw holes provided in the axial direction of anchor sections of an actuator body and a connecting plate, and the bolts are further tightened, whereby the support columns are securely joined and fastened to the actuator body and the connecting plate.

摘要： In a predetermined first state, a distance (D1) in a second direction between a contact portion (Pin) between a input-side engaging part (9) and an input-side engaging part (17) and a rotation center (O) is larger than a distance (D2) in the second direction between a contact portion (Pout) between an output-side engaging part (12) and an output-side engaged part (14) and the rotation center (O). In a locked state or a semi-locked state, a contact portion (C1) between the output-side engaging part (12) and the output-side engaged part (14) is located closer to the rotation center (O) of the output member (4) in a first direction than an imaginary straight line (L) connecting a contact portion (C2) between one pressing surface (13) of the pair of pressing surfaces (13) and a pressed surface (6) to the rotation center (O) of the output member (4).

摘要： The reverse input cutoff clutch includes: a pressed member having a pressed surface around the inner peripheral surface; an input member coaxially arranged with the pressed surface and having an input-side engaging portion arranged on the radially inner side of the pressed surface; an output member coaxially arranged with the pressed surface and having an output-side engaging portion arranged further on the radially inner side than the input-side engaging portion; and an engaging element arranged so as to be movable in a first direction as a direction toward or away from the pressed surface on the radially inner side of the pressed surface. The engaging element has a main engaging element body having a pressing surface and a pivot-support shaft, and a link member. The link member has a first end portion pivotally linked to the pivot-support shaft, and a second end portion pivotally linked to the input-side engaging portion.
