Title:
REVERSE INPUT BLOCKING CLUTCH
Document Type and Number:
WIPO Patent Application WO/2021/054480
Kind Code:
A1
Abstract:
[Problem] To achieve a structure that enables smooth switching from a locked or semi-locked state to an unlocked state when rotational torque is inputted to input members. [Solution] When rotational torque is inputted to input members 2, input-side engagement parts 6 rotate in a rotational direction of the input members 2, and pivoting support shafts 36 are pulled by the input-side engagement parts 6 through linkage members 35 as each of the linkage members 35 pivots about a corresponding one of the pivoting support shafts 36. As a result, a pair of engagement elements 5 respectively move in directions away from a pressed surface 22 (inward in a radial direction), a pressing surface 37 of each of the pair of engagement elements 5 is separated from the pressed surface 22, and an output-side engagement part 13 engages with a pair of output-side mating engagement parts 38 of an output member 3 without rattling through the pair of output-side engagement parts 38 holding the output-side engagement part 13 therebetween from opposite sides in the radial direction.
