SCAFFOLD MEMBER
To provide a scaffold member capable of improving an operation of an operator when a wedge part is changed from a locked state to a stable unlocked state preventing the wedge part from naturally falling down to an insertion part.SOLUTION: A shank 29 is fixed to a wedge side face part 28. A guide hole 27 is provided at a removal prevention body 24. The guide hole 27 is in a slide contact with the shank 29 on the condition that an arc convex surface 25a and a wedge intermediate surface part 30 are in the slide contact during a transition of the removal prevention body 24 by an upward movement from a locked state to an unlocked state. The guide hole 27 includes an inclination acceleration part for increasing an inclination of the removal prevention body 24 moving upwardly and accelerating a transverse orientation by increasing and guiding the inclination of the removal prevention body 24 toward a horizontal member 12.SELECTED DRAWING: Figure 5
【課題】楔部をロック状態から挿通部に自然落下しない安定したアンロック状態へ遷移する場合の作業者の作業を改善できる足場部材を提供する。【解決手段】楔側面部２８には軸部２９が固定されている。抜け止め体２４にはガイド孔２７が設けられている。ガイド孔２７は、抜け止め体２４のロック状態からアンロック状態への上動による遷移の際に、円弧凸面２５ａと楔中間面部３０との摺接した状態を前提として、軸部２９と摺接する。ガイド孔２７は、抜け止め体２４の傾斜を横架材１２に向かって増加させてガイドすることにより、上動する抜け止め体２４の傾斜を増加させて横向きを促進させる傾斜促進部を含む。【選択図】図５
