Abstract
PURPOSE: To prevent a motor coil from burning by providing a connecting part with a fuse between a 1st fixed terminal and a 2nd fixed terminal.
CONSTITUTION: A fine wire portion 13 of a small cross-sectional area as a fuse means is provided at a part of a heater wire 12 connecting a 1st fixed terminal 9 passed through and fixed at the bottom 1a of a case 1 to a heater terminal 11 of a 2nd fixed terminal. Consequently, if a large locked-rotor current caused by motor abnormality flows, self-generated heat in a bimetal 5 and the heater wire 12 increases, and finally the current to the motor is shut off. And if a contact point fusion occurs as a result of fatigue failure of the bimetal during repeated movements of action and reset, the bimetal 5 is continuously energized and also a large locked-rotor current flows through the heater wire 12. If the temperature to be reached at this time is set above the fusing temperature of the fine wire portion 13, the fine wire portion 13 first melts and breaks to shut off the power to the motor.
