A device that can be formed is realized, and the configuration of the opening / closing drive means for forming such an opening for getting on and off can be simplified. Therefore, the configuration of the entire platform protection fence device can be simplified, and the occurrence of failure can be reduced.

According to the third aspect of the present invention, the opening / closing drive means controls the power supply to each coil by the switch, and can selectively supply the alternating current and the direct current to each coil. By selectively supplying an alternating current from a driver to each coil unit, each fence body can be selectively moved. By selectively supplying a DC current from the driver to each coil unit, each fence body can be moved. Can be selectively fixed to prevent movement. In this way, a direct current is selectively supplied to each coil portion, and the fence body on the downstream side in the moving direction for opening from the predetermined getting on / off position is moved to form an opening and opened from the getting on / off position. The movement of the remaining fences arranged on the upstream side in the moving direction can be prevented. As a result, even if an external force acts on the remaining fences, such as when a passenger presses them manually, the remaining fences do not move. Therefore, the opening for getting on and off can be reliably formed at the position corresponding to the position of the getting on and off opening, and safety can be enhanced.
