PURPOSE:To ensure airtightness by constituting a plug door device so that the first and second interlocking bodies are interlocked with the second guide sections in a door front side end of the lower part of a door and that a rail body is interlocked with a holding member in the tail of the door when the door is completely shut. CONSTITUTION:When a door 3 is moved in a shut direction (b) by operation of a going in and out cylinder and an opening and shutting cylinder, the first interlocking body is fitted between a regulatory face 33a of a stopper member 33 and the first guide member 27. When the door 3 is completely shut, the first interlocking body 31 and the regulatory face 33a are closely connected to each other. The first interlocking body 31 and second interlocking body 32 are respectively interlocked with the first guide member 27 and second guide member 28 in a door front side end of the door 3, and a rail body 35 is interlocked with a holding member 34 in the tail of the door. |
