Claims

[Scope of utility model registration request]

A hole having meshing teeth on the side surface and penetrating between the upper and lower end surfaces at the center of rotation, the hole having a shape that engages with the rotating shaft in the rotational direction but allows relative movement in the direction in which the rotating shaft extends. and further includes a synthetic resin gear integrally formed with a pawl that protrudes inward from the hole, and an engaging portion that enters the hole and engages with the hole in the rotational direction, and the pawl enters into the gear. and a rotating shaft having a recess on the side surface, the engaging part of the rotating shaft being inserted into the hole of the gear, and the pawl of the gear entering the recess of the rotating shaft.
gearing.
