The front and rear end portions 12a and 12b are engaged with holes 45 formed in the downward inclined portions 7b and 8b of the link members. As shown in FIGS. 10 and 14, the torsion spring 12 is attached between the downward inclined portions 7 b and 8 b in a state where the lower link 6 is most contracted, and in a direction in which the lower link 6 is contracted as the lower link 6 extends. The urging force 50 works. As shown in FIG. 9, when the gate is in a half-open state, the expansion gate tends to extend without permission due to the weight of the cap lumber 1 a and the upper link 3, but in the direction in which the lower link 6 is contracted as described above. When the urging force 50 of the torsion spring 12 is applied, the vertical rails 2 and the door rods 15 can be stopped at arbitrary positions in the left-right direction, and the half-open state can be maintained. Moreover, the urging | biasing force 50 of the torsion spring 12 is working in the direction which shrinks the lower link 6 in that way, Therefore The operating force at the time of shrinking a gate can be reduced.

  The intermediate vertical beam 13 is inserted through the upper end of a shaft 26 that connects the ends of the first upper link member 4 and the second upper link member 5, and the first lower link member 7 and the second lower link member 8.

By providing the intermediate vertical rail 13 in this way, the movement of the upper link 3 and the lower link 6 when the gate extends and contracts, and the upper link 3 and the lower link 6 do not move separately. Then it will expand and contract. The vertical rail 2 does not tilt in the left-right direction when the gate extends or retracts or is in a half-open state. In addition, the robustness and durability of the entire gate can be improved.

  As shown in FIGS. 1 and 2, two casters 14 are attached to the lower end of the first to fourth vertical bars 2 from the left with two gaps in the expected direction. The mounting intervals p1, p2 of the casters 14 are alternately changed between the crosspieces 2, 2,. The caster 14 uses a free caster that rotates around a vertical axis 14a. As shown in FIG. 11, when the gates are contracted, the casters 14 are prevented from interfering with each other, as shown in FIG. There is an advantage that the folding width L can be reduced.
