PROBLEM TO BE SOLVED: To provide a circuit breaker whose internal mechanism is miniaturized.SOLUTION: A coil bobbin 51 of a display mechanism 50 is connected to a housing main body. A coil support part 51a of the coil bobbin 51 is provided with a coil 52, and supports a push pin 53 and a plunger 54. An interlocking plate support part 51b of the coil bobbin 51 supports an interlocking plate 57 along a direction (front-and-rear direction) perpendicular to a moving direction (up-and-down direction) of the plunger 54 so that the interlocking plate 57 is freely movable. The interlocking plate 57 is urged forwards by a reset spring 62 interposed between the interlocking plate and the interlocking plate support part 51b. The plunger 54 is inserted in a fitting recess portion 57b of the interlocking plate 57, and the fitting between the plunger 54 and the fitting recess portion 57b restricts the movement of the interlocking plate 57 by the reset spring 62. |
