ABSTRACT:
In a bus bar connector, a ball bearing (20) having an inner wheel (21), an outer wheel (22) and plural balls (23) is provided between a guide rod (7) and a guide hole (3b) of the bus bar (3). When the center of gravity of the bus bar (3) is moved by electromagnetic force due to accidental overcurrent, a torque generated by friction force acting between the guide rod (7) and the inner wheel (22) rotates only the inner wheel (22) and is not conveyed to the bus bar (3).
