[Scope of utility model registration request]

A plurality of diagonal bars 5 are arranged between a plurality of vertical bars 4, 4 so as to be inclined in mutually opposite directions, and support shafts 8, 10 are provided at intersections formed by these bars 4, 5, respectively.
In the telescopic gate door equipped with a telescopic mechanism which is rotatably supported on each other by the diagonal bars 5, the diagonal bar 5b inclined in at least one direction among the diagonal bars 5 is constituted by a main bar 5b1 and an auxiliary bar 5b2. The telescopic gate is characterized in that these crosspieces 5b1 and 5b2 are fitted and connected so that they can slide relative to each other.
