To provide a barricade device capable of minimizing a decrease in strength while maintaining a size satisfying a specification when in use, and capable of changing a width narrowly so as to be less than a specified size when not in use.SOLUTION: A barricade device comprises: a first leg rod 11 and a second leg rod 12 being spaced apart from each other, which can be opened and closed; and horizontal beam sections 13, 14 connecting the first leg rod and the second leg rod. The horizontal beam sections 13, 14 are configured by slidably connecting an end component tube 22 and a middle component tube 23. A stopper mechanism is provided which enters and fixes an overlapping part 25 where the end component tube 22 and the middle component tube 23 overlap with each other. Thus, it is possible to change between a first state which satisfies a specification relating to a prescribed length (1200 mm) and a second state which does not satisfy the specification by sliding and contracting the end component tube 22 and the middle component tube 23.SELECTED DRAWING: Figure 1
【課題】使用時には規定を満たす大きさを維持しながら強度の低下を最小限に抑え、非使用時には規定の大きさを下回るよう幅を狭く変化させることが可能なバリケード装置を提供する。【解決手段】互いに離間して配置され各々が開閉可能である第１脚杆１１及び第２脚杆１２と、第１脚杆及び第２脚杆を繋ぐ横梁部１３、１４と、を備えたバリケード装置であって、横梁部１３、１４は、端部構成管２２と中部構成管２３をスライド可能に繋げて構成され、端部構成管２２と中部構成管２３が重なり合った重合部分２５に入り込んで固定するストッパ機構部を有し、所定の長さ（１２００ｍｍ）に係る規定を満たす第１状態と、端部構成管２２と中部構成管２３をスライドさせて収縮し規定を満たさない第２状態とに変化可能である。【選択図】図１
