To securely fix the turning of a caster about a vertical axis.SOLUTION: A turning and fixing apparatus of a caster has a pair of engaging portions 2 separated from each other, and an intermediate portion 3 between the pair of engaging portions 2. While the pair of engaging portions 2 engage with struts 81 of a movable scaffold 8 to be laid between a pair of casters 9, the intermediate portion 3 holds a wheel 93 of the caster 9 and engages with a brake operation lever 96 of a holder 92 freely turning about a vertical axis, thereby receiving movement in which the brake operation lever 96 tries to turn around the vertical axis.SELECTED DRAWING: Figure 1
【課題】キャスタの鉛直方向軸回りの転回を強固に固定する。【解決手段】相互に離間する一対の係合部2と、一対の係合部2の間の中間部3と、を有し、一対の係合部2それぞれが移動式足場8の支柱81と係合して一対のキャスタ9の間に掛け渡された状態で、中間部3が、キャスタ9の車輪93を保持するとともに鉛直方向軸回りに転回自在なホルダ92のブレーキ操作レバー96と係合し、ブレーキ操作レバー96が鉛直方向軸回りに転回しようとする動きを受け止める。【選択図】図1
