PROBLEM TO BE SOLVED: To securely maintain the height position of a seat surface of a seat even if a reverse input is given from the seat surface of the seat therein by adding a simple structure. SOLUTION: This reverse input prevention clutch comprises an input side member 2 to which torque is inputted, an output side member 3 from which torque is outputted, a stationary side member 4 of which rotation is constrained, lock means 3a, 4a, 5, and 6 installed between the stationary side member 4 and the output side member 3 and locking the output side member 3 and the stationary side member 4 against the reverse input torque from the output side only in one rotating direction only, an unlocking means 2a installed on the input side member 2 and releasing the locked state by the lock means 3a, 4a, 5, and 6 in one rotating direction against the input torque from the input side member 2, and torque transmission means 2c and 3c installed between the input side member 2 and the output side member 3 and transmitting the input torque in both rotating directions from the input side to the output side member 3 with the locked state only in one direction by the lock means 3a, 4a, 5, and 6.
