When the doorway 2 is opened and closed by the telescopic gate, the handle 20 of the locking frame 17 is gripped and the telescopic gate body 6 is extended and contracted in the longitudinal direction of the gate. At this time, since the vertical rail 13 and the horizontal rails 7 to 10 are rotatable at the part where the rivet 34 is fixed, the four sets of connecting bodies 22 to 25 are zigzag in a horizontal plane by relative rotation at this part. The telescopic gate body 6 expands and contracts.
