Claims

[Scope of utility model registration request]

A driven rotary body (or a driving rotary body), a displaceable driving rotary body (or a driving rotary body), and an intermediate rotary body that is rotatably supported by a lever and that transmits the driving force of the driving rotary body to the driven rotary body. and a guide body disposed coaxially with the drive rotor and capable of coming into contact with the intermediate rotor, so that the intermediate rotor comes into pressure contact with the driven rotor due to rotation of the drive rotor, and the guide body is arranged coaxially with the drive rotor and can be brought into pressure contact with the driven rotor. When a load is applied, the driving rotating body (or the driven rotating body) is displaced so that the intermediate rotating body can pass between the driving rotating body and the driven rotating body, and the intermediate rotating body continues to drive the drive rotor even after passing between the drive rotor and the driven rotor, and after passing between the intermediate rotor and the driven rotor,
An overload prevention device for a rotation transmission mechanism, wherein the intermediate rotating body is attached to the guide body, rotates at a low speed, and is gently attached to the driven rotating body again to transmit driving force.
