Claims

[Scope of utility model registration request]

(1) A motor, a reduction gear mechanism including a slip means to reduce the rotation of the motor, a main gear provided at the final stage of the reduction gear mechanism, a cam rotatable integrally with the main gear, and a time setting knob. In a manual timer consisting of a contact mechanism that is operated by the cam at time-up, a slight notch is formed on the circumference of the main gear in the time setting rotation direction from the zero return position, and the range of this notch is determined after the zero return position. A manual characterized in that the main gear and the time setting knob are rotatable, and a spring means is provided for the time setting knob to act in a direction opposite to the rotation in the zero return direction after the zero return. timer.

(2) An arcuate groove approximately corresponding to the setting angle of the time scale is formed on the back surface of the time setting knob, and an arcuate wire spring is loosely inserted into the groove and one end is fixed to the upper cover. The manual timer according to claim 1, wherein the manual timer is fixed to the groove portion and the other end thereof can be secured to the end face of the groove portion.
