<p>PROBLEM TO BE SOLVED: To provide a vehicular electric circuit breaker device in which terminals to load power thereto can be prevented from being exposed during both breaking and connecting operations, and further, power can be connected/disconnected only by a rotating operation.SOLUTION: The vehicular electric circuit breaker device includes: a jack housing 7 disposed in an accommodation space 3 inside of a vehicle-side pedestal 2 for accommodating a first terminal couple 4; a second terminal 5 provided within the jack housing 7 oppositely to the first terminal couple 4 so as to be in contact with or separated from the first terminal couple 4; and a tubular operation cylinder 6 disposed so as to concentrically surround the jack housing 7. The second terminal 5 is supported via a guide groove 8 that is formed in an axial direction on a peripheral wall surface of the operation cylinder 6 and by rotating the operation cylinder 6, the second terminal 5 is in contact with or separated from the first terminal couple 4, such that breaking and connection of an electric circuit of a vehicle can be switched via the first terminal couple 4.</p> |
