PROBLEM TO BE SOLVED: To provide a workpiece hoisting tool capable of surely holding a workpiece by a simple structure and operation and preventing the workpiece from being damaged even when it is rotated around an axis while hoisting the workpiece.SOLUTION: A workpiece hoisting tool 1 for hoisting a workpiece W in which hoisting tool insertion holes H are respectively formed in both end parts in the longitudinal direction, includes a main body part 2 having a longitudinal dimension approximately equal to a longitudinal dimension of the workpiece W, a pair of turning parts 3 rotatably supported respectively by both end parts in the longitudinal direction of the main body part 2, and a pair of workpiece sliding parts 5 attached to each of the pair of turning parts 3 and having sliding surfaces with an approximately arc-shaped cross section. The workpiece sliding parts 5 are inserted in the hoisting tool insertion holes H of the workpiece W or pulled out from the hoisting tool insertion holes H in accordance with the rotation of the turning parts 3. When the workpiece W is rotated around the axis while being suspended, an inner peripheral surface Hs of the hoisting tool insertion holes H of the workpiece W slides with a sliding surface of the workpiece sliding parts 5.SELECTED DRAWING: Figure 4
【課題】簡略な構成及び操作によってワークを確実に保持することができると共に、ワークを吊り上げた状態で軸回りに回転させてもワークが損傷することのないワーク吊り具を提供する。【解決手段】長手方向両端部に吊り具挿入用穴Hがそれぞれ形成されたワークWを吊り上げるためのワーク吊り具1であって、ワークWの長手方向寸法と略等しい長手方向寸法を有する本体部2と、本体部2の長手方向両端部に回動可能にそれぞれ支持された一対の回動部3と、一対の回動部3にそれぞれ取り付けられて、断面略円弧形状の摺動面を有する一対のワーク摺動部5とを備え、回動部3の回動に伴って、ワーク摺動部5がワークWの吊り具挿入用穴Hに挿入されまたは吊り具挿入用穴Hから引き出され、ワークWを吊り上げた状態でその軸回りに回転させた時に、ワークWの吊り具挿入用穴Hの内周面Hsがワーク摺動部5の摺動面と摺動する。【選択図】図4
