PROBLEM TO BE SOLVED: To preclude permanent deformation by forming a lever interlock switch from an elastic material and prevent a microswitch actuator from breakage even in case the interlock switch is over-pushed. SOLUTION: A lever interlock switch is made of an elastic material, and the forefront of a microswitch pressing part 4b-2 is arranged to collide with the front side-face 1-1 of a bracket interlock switch 1. Thus the deformation part of the lever interlock switch can be prevented from permanent deformation, and it is possible to push in the actuator 2-1 of microswitch 2 certainly. Because the forefront of the microswitch pressing part 4b-2 of the lever interlock switch runs against the front side-face 1-1 of the bracket interlock switch 1, the actuator 2-1 can be prevented from breakage even in case the lever interlock switch 4b is over-pushed.
