PROBLEM TO BE SOLVED: To provide an electrically openable gate which can charge electric power from a power source on a stopper support side to a motor driving power source without through an electrically connecting means. SOLUTION: The electrically openable gate is comprised of a door body, a motor 40, a rechargeable battery 39, and the power source. The door body has a wheel apparatus and is movable along a rail over a predetermined frontage, from the stopper support side on one end of the gate to the hanging support side on the other end, or vice versa. The motor 40 is arranged in the gate body for driving the wheel apparatus. The rechargeable battery 39 is arranged in the door body for supplying driving power to the motor 40. The power source is arranged on the stopper support side and supplies charging electric power to the rechargeable battery 39 during closing operation of the gate, i.e., when the one end of the door body abuts on the stopper support. According to the electrically openable gate, electric power from the power source on the stopper support side is fed to the rechargeable battery 39 on the gate side via non- contact type feeder devices 11 and 12 which have functions of electromagnetic induction. |
