Claims

[Scope of utility model registration request]

A pawl fitting groove with a deep groove in the center is formed in the wheel ring with a sprocket wheel on the outer periphery, and an arc-shaped pawl with a protrusion on the outside center is fitted into the groove and swings like a seesaw. At the same time, the retaining shape formed on one end of this pawl is made to protrude inwardly from the other end so as to engage with the ratchet teeth of the hub body that is inserted into the wheel ring, and the wheel ring is rotated in the reverse direction. Or, when stopped, the other end of the pawl is pushed up by the ratchet teeth, and the engagement between the shape retention and the ratchet teeth is released.
