Claims

[Scope of utility model registration request]

A rotational force is applied in a predetermined direction by a torsion spring, and a rotating body rotated by an operation part and one end side supporting a first gear are rotatably supported by a shaft. and a connecting rod in which one end of the torsion spring is locked in a long hole formed at the other end;
a second gear that can mesh with the gear of the first gear, and when the rotating body is rotated to a first rotating position by the operating portion, one end of the torsion spring displaces the long hole of the connecting rod. After the connecting rod is rotated in a predetermined direction to move the first gear to a meshing position where it meshes with the second gear, the rotating body is rotated by the operating section into a second rotating position. A gear meshing mechanism characterized in that the gear meshing mechanism is configured such that when the gears are rotated to a certain position, a compression force is applied to both gears by the bending force of the torsion spring.
