<p>The invention is about a crosswalk rotator circuit breaker. In particular, the invention does not directly connect the barrier body and the rotating motor but indirectly connect to have the blocking barrier to rotate by the frictional force through the pressuring part. Thus, a crosswalk rotator circuit breaker can prevent the rotating motor or blocking barrier, even when a pedestrian puts external force to forcefully rotate the blocking barrier. For this purpose, the crosswalk rotator circuit breaker includes: a blocking barrier that opens and closes the pedestrian passage according to the rotation of barrier bars; a rotation motor rotating located on the outer surface of the above blocking barrier to rotate the blocking barrier; a friction plate that allows the blocking barrier to rotate by the friction force when the rotation motior rotates, which is located on either inner or outer space of the blocking barrier; a pressuring part that pressures the above friction plate to increase the friction force, located either between the above rotation motor and the friction plate or between the friction plate and blocking barrier.</p> |
