The box 11 is equipped with a connector relay board 141 to connect an external power cable 13 connected to a floor power source (not illustrated in the figure). A fixed cable 192 in the box 11 is connected to the relay board 141 and the beginning end part of a movable cable 191 is connected to the terminating end part thereof through a circuit breaker 171.
