The strength of the conductive wire (2a) is such that even if the breaking stress acts on any part of the blocking rod main body (1) externally (such as a car collision), it is cut along with the breaking of the blocking rod main body (1). As shown in the drawing, a material having a wire diameter or a wire diameter is used, and the innermost surface of the hollow rod (f) is folded back from the breaker mounting portion which is the base end side of the shutoff rod main body (1) to the loop. The base end side of the resistance part (Ra) (Rb) (Rc) (Rd) (Re) is different from the detection part (2) on the base end side due to the difference in the wire breakage due to breakage.

It is configured by connecting to. Further, (R 1 ) is a resistance that prevents the voltmeter (2b) from being short-circuited.

By the way, of the hollow rods (a) to (f) in this device, the most distal hollow rod (f) is not provided with a resistance portion.
This is because the blocking rod is supported by the circuit breaker in a cantilevered manner, so that the position where an external impact is applied to the blocking rod goes to the tip side,
Since the impact stress is easily absorbed by the bending deformation force of the entire blocking rod, when an external impact is applied only to the cutting edge hollow rod (f), the impact stress is the bending deformation force of the entire blocking rod. Even if impact stress is applied to the blocking rod even if it exceeds the limit of the bending deformation force of the blocking rod as a whole, the blocking rod is actually a hollow rod (e) adjacent to the hollow rod (f) or its hollow rod. Hollow rod (a) on the mounting side from (e)
This is because breakage occurs in any of (d).
