STORE FIXTURE LEG

To provide a leg capable of changing a longitudinal size, dispensing with preparation of a tool, while suppressing the number of components, and suppressing occurrence of a trouble such as loss of a component such as a bolt constituting a fixing mechanism.SOLUTION: A leg 4 has a constitution including an outer cylinder 41, an inner cylinder 42 fitted into the outer cylinder 41 relatively movably, a positioning member 43 arranged in the inner cylinder 42 for positioning moderately the outer cylinder 41 and the inner cylinder 42, and a stationary member 44 for keeping or releasing a positioning state by restricting or releasing the movement of the positioning member 43.SELECTED DRAWING: Figure 7 【課題】工具を別途準備の必要がなく、部品数を抑制しつつ、また、固定機構を構成するボルト等の部品を紛失する不具合の発生を抑制しつつ、長手寸法を変更可能な脚柱を実現する。【解決手段】外筒４１と、この外筒４１に相対移動可能に嵌入される内筒４２と、この内筒４２内に配され外筒４１と当該内筒４２との位置決めを節度的に行う位置決め部材４３と、この位置決め部材４３の動きを制限又は解放して位置決め状態を保持又は解除する固定部材４４とを具備する脚柱４の構成を採用する。【選択図】図７
