Claims

[Scope of utility model registration request]

A pair of gears are provided on the outer periphery, in which teeth of the same shape and number are arranged at different positions in the circumferential direction, and are arranged facing each other on the same axis, and these gears engage with each other on the inner surface to rotate. A locking portion that allows play in each direction is formed, and an opening for accommodating a compression spring curved in an arc shape along the outer periphery of the gear is formed on opposing surfaces of these gears, and one end of the opening A receiving portion located at the other end of the opening and contacting the other end of the compression spring is formed on one of the gears, and a receiving portion located at the other end of the opening and contacting the other end of the compression spring is formed on the other gear. In the gear device, in which projections protruding from both ends of the compression spring are formed at both ends of the opening, the two sheets of the compression spring are arranged such that a recess along an outer peripheral edge of the gear of the opening faces each other. A gear device characterized by being formed between gears.
