PROBLEM TO BE SOLVED: To provide a tool for attaching/detaching a heavy component capable of attaching/detaching the heavy component to/from an attachment part without generating an interference with insertion holes formed in the heavy component.SOLUTION: A tool 10 for attaching/detaching a heavy component 5 is used for attaching/detaching the heavy component 5 to be fixed on a wall face 1, and includes a screw part 11 for being screw-fitted with a screw hole 2 of the wall face 1, and a barrel 12 continuously arranged to the screw part 11. Diameters of the screw part 11 and the barrel 12 are smaller than that of insertion holes 3 of the heavy component 5, and the whole of the tool is formed into a rod-like shape. The tool is provided with: a tapered part, such as a truncated conical part 13, which is arranged at an end opposite to the screw part 11, has an outer shape smaller than a diameter of the insertion holes 3, and is formed so as to be tapered as it gets away from the barrel 12; and a groove 14 which is arranged between the barrel 12 and the truncated conical part 13, and in which an edge part of the insertion holes 3 of the heavy component 5 can fall.SELECTED DRAWING: Figure 2
【課題】取り付け部に対して重量部品を脱着させる際に、重量部品に形成された挿通穴との干渉を生じさせずに脱着させることができる重量部品の脱着治具の提供。【解決手段】本発明は、壁面1に固定される重量部品5の脱着に際して用いられ、壁面1のねじ穴2に螺合するねじ部11と、このねじ部11に連設される胴部12とを有し、ねじ部11と胴部12を重量部品5の挿通穴3の径寸法よりも小さな径寸法に設定し、全体が棒状に形成された重量部品5の脱着治具10において、ねじ部11とは反対側の他端に設けられ、挿通穴3の径寸法よりも小さな外形に形成され、胴部12から離れるに従って先細となるように形成された先細部、例えば截頭円錐部13と、胴部12と截頭円錐部13との間に設けられ、重量部品5の挿通穴3の縁部の落ち込みが可能な溝14とを備えている。【選択図】図2
