A reverse-input blocking clutch, comprising: a pressed member having a pressed surface around an inner peripheral surface thereof; an input member having an input-side engaging portion arranged on an inner side in a radial direction of the pressed surface, and coaxially arranged with the pressed surface; an output member having an output-side engaging portion on the inner side in the radial direction of the pressed surface arranged further on the inner side in the radial direction than the input-side engaging portion, and coaxially arranged with the pressed surface; and an engaging element having a pressing surface facing the pressed surface, an input-side engaged portion engageable with the input-side engaging portion, and an output-side engaged portion engageable with the output-side engaging portion, and arranged on the inner side in the radial direction of the pressed surface so as to move in a first direction as a direction away from or toward the pressed surface; when rotational torque is input to the input member, the engaging element displacing away from the pressed surface based on engagement between the input-side engaging portion and the input-side engaged portion, engaging the output-side engaged portion with the output-side engaging portion, and transmitting the rotational torque input to the input member to the output member, and when rotational torque is reversely input to the output member, the engaging element engaging the output-side engaging portion with the output-side engaged portion, pressing the pressing surface against the pressed surface, and frictionally engaging the pressing surface with the pressed surface; and an elastic member elastically held between the output-side engaging portion and the engaging element so as to press the output-side engaging portion to a side away from the pressed surface in the first direction and press the engaging element to a side closer to the pressed surface in the first direction, characterized in that the elastic member includes an elastic pressing portion arranged at a position deviated in the axial direction with respect to the output-side engaged portion with regard to the axial direction of the pressed surface at a position overlapping the output-side engaging portion with regard to the first direction, and elastically pressing the elastic pressing portion against the output-side engaging portion, the elastic member is configured by a leaf spring, and the leaf spring has a first through hole passing through in the first direction at a location aligned with the output-side engaged portion, and the elastic pressing portion is arranged on both sides of the first through hole with regard to the axial direction of the pressed surface. a pressed member having a pressed surface around an inner peripheral surface thereof;
