Claims

[Scope of utility model registration request]

The main shaft for time setting is rotated by the rotation of the driving part via a speed reduction mechanism, and a thermoplastic synthetic resin cam is fitted to a cam collar fixed to the main shaft, and rotation is applied to the cam via the cam collar. In a timer cam that opens and closes contacts by transmitting power and rotating the cam, a space is provided between the inner circumferential surface of the cam, where the outer circumferential surface of the cam collar fits, and the outer circumferential surface of the cam, and the wall thickness of both the inner and outer side surfaces is increased. A timer cam that is made up of equal parts.
