<p><P>PROBLEM TO BE SOLVED: To provide an airtight sliding door device capable of reducing a vertical dimension. <P>SOLUTION: A roller 25 as an engaging member movably engaged with a guide rail 20 as a guide member rolls with respect to the guide rail 20, so that a door body 1 for opening/closing an opening can be moved for opening/closing. The door body 1 is provided with a door body thickness-direction moving means which moves the door body 1 in the thickness direction of the door body, so that a section between one thickness-direction side of the door body 1 on an arrival in a full-closing position and an immovable member can be put into an airtight state by an airtight member arranged in the immovable member. The door body thickness-direction moving means comprises a door body free-movement and return means 64 for enabling the door body 1 to move freely in the thickness direction of the door body with respect to the roller 25 and return to an original position, and a pushing means 70 which is arranged in the immovable member via the guide rail 20 and a bracket 71 for the pushing member, so as to push the door body 1, moving for closing toward the full closing position, to the side of the airtight member in the thickness direction of the door body 1. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
