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: 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: Provided is a reverse input blocking clutch capable of easily releasing a state in which rotation of an output member is prevented or suppressed.
The reverse input blocking clutch 5 includes an input member 14, an output member 15, a pressed member 16, and an engaging member 17. When a rotational torque is inputted to the input member 14, the engaging member 17 moves in a direction away from a pressed surface 28 of the pressed member 16 due to engagement with the input member 14, and transmits the rotational torque inputted to the input member 14 to the output member 15 due to engagement with the output member 15; and when rotational torque is reversely inputted to the output member 15, moves in the direction closer to the pressed surface 28 based on engagement with the output member 15, and by being pressed against the pressed surface 28 does not transmit the rotational torque reversely inputted to the output member 15 to the input member 14, or transmits only part thereof to the input member 14 due to engagement with the input member 14.

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.
