Abstract
A reset knob 20 is mounted to a tip end of a shaft 16. A torsion spring 21 and a returning motion-preventing lock 22 are bent and accommodated in the reset knob 20. The returning motion-preventing lock 22 can rotate around a reset-knob fulcrum 20a of the reset knob 20 by a load of the torsion spring 21. Therefore, the returning motion-preventing lock 22 jumps out from inside of the reset knob 20 which is firmly connected together with the shaft 16 by a force of the torsion spring 21, thereby preventing the shaft 16 and the reset knob 20 from returning to an initial position. Further, since the returning motion-preventing lock 22 can easily be accommodated in the reset knob 20 manually, a reset operation for returning the shaft 16 to its original initial position can be carried out easily.
Claims4
A power breaker comprising:
- a pair of terminals inserted in a power circuit for connecting a battery of a vehicle to loads provided in various portions of the vehicle;
- and
- a shaft capable of connecting and separating said terminals to and from each other via sliding movement of said shaft, said shaft being movable from an initial position where said terminals are connected to each other to an interruption position where said terminals are separated from each other, thereby interrupting said power circuit,
- wherein said shaft comprises one end having a returning motion-preventing lock which projects from said shaft when said shaft interrupts said power circuit to prevent said shaft from returning to said initial position.
