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.
