To provide a holding releasing device of a structure which can make the projection length of an expansion mechanism from a member shorter after a plurality of members are switched from a holding state where they are serially bound to a releasing state.SOLUTION: A holding releasing device 100 is for switching between a holding state where a plurality of members 10 are serially bound not to be displaced from each other and a releasing state where the members 10 can be displaced from each other. When a fixing releasing unit 40 is operated to switch from a fixed state to a released state, binding of a first member 11 and a second member 12 is released to enable mutual separation and displacement of the members 10. An expansion mechanism 30 is changed to be shortened by biasing of a biasing unit 50. The other end 30b of the expansion mechanism 30 is moved to a side opposite to one end 30a relative to the second member 12 to reduce the projection length L of the expansion mechanism 30 from the second member 12.SELECTED DRAWING: Figure 4

    【課題】複数の部材が直列状態で拘束された保持状態から解放状態に切り替わった後において、部材からの伸縮機構の突出長をより短くすることが可能な構造の保持解放装置を提供する。【解決手段】保持解放装置100は、複数の部材10が直列に並ぶ直列状態で拘束されて相互に変位不能となっている保持状態と、複数の部材10が相互に変位可能な解放状態と、に切り替える保持解放装置100である。固定解除部40が作動することにより固定状態から解除状態に切り替わると、第1部材11と第2部材12との拘束が解除されることで複数の部材10が相互に分離及び変位可能となるとともに、付勢部50による付勢に従って伸縮機構30が短縮状態に変化するとともに伸縮機構30の他端部30bが第2部材12に対して相対的に一端部30aの側とは反対側に移動して、第2部材12からの伸縮機構30の突出長Lが減少する。【選択図】図4
