Abstract
A ratchet mechanism of the present disclosure includes a first ratchet gear, a second ratchet gear and a compression coil spring. The compression coil spring applies a force acting toward the first ratchet gear to the second ratchet gear. In the second ratchet gear, a cylindrical boss is formed. The center of gravity of the compression coil spring is arranged on the side of one end portion with respect to the center of the compression coil spring in a longitudinal direction. The compression coil spring is inserted into a boss from the side of the one end portion, and thus the center of gravity of the compression coil spring is arranged on the side of the first ratchet gear with respect to the tip end of the boss.
