PROBLEM TO BE SOLVED: To efficiently carry out the lifting operation of an opening/closing device building material.SOLUTION: This lifting device is provided with: a body member 10 that is formed so as to be positioned at one end side inside a building opening x and at the other end side outside the building opening x intersecting the building opening x; and a weight member 20 that is positioned on the other end side of the body member 10. The body member 10 has a mounted part 10a for mounting a building material b to a corresponding position in the building opening x, and a lifted part 10b that enables lifting and holding at a corresponding position outside the building opening x. The weight member 20 is positioned closer to the other end side than the lifted part 10b, and provided so as to be able to adjust moment in which a distance from the lifted part 10b is set as an arm length L.SELECTED DRAWING: Figure 1
【課題】 開閉装置用建材の吊上げ作業を効率的に行う。【解決手段】建物開口部xに交差してその一端側が建物開口部x内に位置するとともに他端側が建物開口部x外に位置するように形成された本体部材10と、この本体部材10の前記他端側に位置するウェイト部材20とを備え、本体部材10は、建物開口部x内に対応する位置に建材bを載置するための被載置部10aを有するとともに、建物開口部x外に対応する位置には吊持されることを可能にする被吊持部10bを有し、ウェイト部材20は、被吊持部10bよりも前記他端側に位置するとともに被吊持部10bからの距離を腕の長さLとしたモーメントの調整が可能に設けられている。【選択図】 図1
