To provide a power supply circuit breaker device having a good operability of an operation lever.
A power supply circuit breaker device 1 includes: a base housing 2 having a first fitting wall 4 and a cam pin 7; a lever housing 20 having a second fitting wall 22; and an operation lever 40 freely and rotatably supported by the lever housing 20 and having a cam groove 43 guiding the cam pin 7. In the power supply circuit breaker device 1, the first fitting wall 4 and the second fitting wall 22 are set in a state that both are partially overlapped with each other to such a lever fitting start position that the cam pin 7 intrudes into the cam groove 43 of the operation lever 40, and the cam pin 7 moves in the cam groove 43 due to rotation of the operation lever 40 to make a fitting force act between the first fitting wall 4 and the second fitting wall 22. In the base housing 2 and the lever housing 20, restriction ribs 10 and 30 that are mutually locked between the lever fitting start position and a lever fitting completion position to guide fitting between the first fitting wall 4 and the second fitting wall 22 and that restrict inclination in a rotation direction L of the operation lever 40, are provided.
