To provide a coil spring type one-way clutch, having no risk of damage due to load in the locking direction.

One end of a coil spring (72) is locked on a member (9) side, and the driving force in the locking direction acting on one end of the coil spring (72) is received by the locking part. The locking part is configures so that one end of the coil spring (72) is drawn out to form a drawing part (72c), and the distal end of the drawing part (72c) is rounded to form a ring-like part (72b). A screw (94) is inserted in the ring-like part (72b), and the screw (94) is screwed in a tapped hole formed in a member (9) to thereby fix the ring-like part (72b) to the member (9).
