Abstract: The reverse input shutoff clutch includes: an input member, an output member coaxially arranged with the input member, a pressed member having a pressed surface, and an engaging element. The engaging element, when rotational torque is inputted to the input member, moves in a direction away from the pressed surface due to engagement with the input member and transmits the rotational torque to the output member, and when rotational torque is reversely inputted to the output member, moves in a direction toward the pressed surface due to engagement with the output member, and prevents or suppresses relative rotation between the output member and the pressed member.

Abstract: Construction of a toroidal continuously-variable transmission is achieved that simplifies the manufacture of parts, management of parts and assembly work, is able to easily reduce costs, stabilizes speed change operations, and is processed easily. An outer ring 16b of a thrust rolling bearing is supported so as to be able to pivotally displace by engaging a concave section 24 that is provided on the outside surface of the outer ring 16b with a cylindrical convex surface 22 of a support beam 23a of a trunnion 7b. Displacement of the outer ring 16b in the axial direction of the support beam 23a is limited by engaging a concave groove 27 that is formed around the inside surface of the concave section 24 in the circumferential direction around the support beam 23a with a protrusion 28 that is formed around the outer-circumferential surface of the support beam 23a.

Abstract: 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.

Abstract: The electric motor with a reverse input cutoff clutch has an output shaft. The output shaft is configured by connecting a first shaft and a second shaft that are coaxially arranged with each other via the reverse input cutoff clutch. The second shaft is rotatably supported to a housing by one radial bearing. The reverse input cutoff clutch has a function that, when rotational torque is inputted to the first shaft, transmits the rotational torque inputted to the first shaft to the second shaft, and when rotational torque is reversely inputted to the second shaft, completely cuts off the rotational torque reversely inputted to the second shaft, and does not transmit the rotational torque to the first shaft, or transmits a part of the rotational torque to the first shaft, and cuts off the remaining part.
