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 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: Fletching wear caused by elastic deformation in the axial direction of an input-side disk 2c due to thrust force of a pressure device is prevented. A female-spline section 13a formed around the middle section in the axial direction of the inner-circumferential surface of a center hole 19 in the input-side disk 2c and a male-spline section 12a formed around the outer-circumferential surface of one end section in the axial direction of an input rotating shaft 1b engage with a spline engagement. A disk-side fitting surface section 22 formed around a portion of the inner-circumferential surface of the center hole 19 in the input-side disk 2c that is adjacent to the other end side of the female-spline section 13a and a shaft-side fitting surface section 23 formed around a portion of the outer-circumferential surface of the input rotating shaft 1b that is adjacent to the other end side of the male spline section 12a are fitted together with an interference fit.

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.

Abstract: A reverse input blocking clutch includes an input member, an output member, a pressed member, and an engaging member. When a rotational torque is inputted to the input member, the engaging member moves in a direction away from a pressed surface of the pressed member due to engagement with the input member, and transmits the rotational torque inputted to the input member to the output member due to engagement with the output member; and when rotational torque is reversely inputted to the output member, moves in the direction closer to the pressed surface based on engagement with the output member, and by being pressed against the pressed surface does not transmit the rotational torque reversely inputted to the output member to the input member, or transmits only part thereof to the input member due to engagement with the input member.

Abstract: An electric vehicle driving device includes a first motor, a second motor, a transmission device to which power of at least one of the first motor and the second motor is transmitted, and an output member that rotates with power output from the transmission device. A rotation axis of the first motor, a rotation axis of the second motor, and a rotation axis of the transmission device are arranged in parallel to a rotation axis of the output member. When seen from an axial direction parallel to the rotation axis of the output member, the rotation axis of the first motor is located on one side of a straight line passing through the rotation axis of the output member and the rotation axis of the transmission device and the rotation axis of the second motor is located on the other side of the straight line.
