PROBLEM TO BE SOLVED: To reduce opening-closing incompletion due to ice when a gate device of a type in which an end part of a door of a closing state abuts on an abutting object member, is used in a cold district.SOLUTION: A flow passage 123 for moving air is formed inside a door 12 of a gate device 1. A part of the flow passage 123 passes through the inside of an end part 122 being a part abutting on a protective barrier 9L in a closed state of the door 12. A flow passage 115 for moving the air is formed inside a casing 111 of the gate device 1. The air flowing through the flow passage 115 is heated by a heater 117. When the door 12 is in the closed state, the flow passage 123 and the flow passage 115 communicate with each other, and form a circulation flow passage of the air. The air heated by the heater 117 circulates in the circulation flow passage by an air blower 116. Since the end part 122 is warmed up by the circulating heated air, even when the gate device 1 is used in a cold district, the door 12 is not fixed to the protective barrier 9L by ice, and opening-closing incompletion is not caused.SELECTED DRAWING: Figure 7 |
