Description

  The present invention relates to a joint device for a connecting passage that connects left and right buildings provided via joint portions.

  Conventionally, this type of joint device for a crossing passage uses a pair of slide side walls that are slidably movable in the left-right direction on the outer wall in which the opening for the crossing passage is formed. It is comprised so that a clearance gap may not be made between the crossing passage and the opening part for crossing passages (patent documents 1 and 2).

  However, if such a slide side wall is not dimensioned enough on both sides of the opening for the crossing passage (there is no clearance for the swing motion width), the building or the slide side wall itself may be damaged when it is shaken by an earthquake. There is a drawback that it cannot be installed in such a place.
