PROBLEM TO BE SOLVED: To provide a height adjustment tool of a device for lifting a heavy object, to be used for safely lifting and moving heavy objects such as furniture with legs, a care bed with fixed legs, and the like.SOLUTION: A height adjustment tool 2 is used for adjusting the installation height of a device 90 for lifting a heavy object W by leverage, including: an action part 93 for touching and lifting the heavy object W; a lever 94 to which force is applied; a rotation shaft 95 as a fulcrum; and a wheel 92 for movement. The height adjustment tool 2 having a predetermined height Ha, includes: a wheel holding part 5 formed on a top face 3, for fixing the wheel 92; and inclined surfaces 7 formed at edge parts of the top face 3, for widening the range of the swing of the action part 93 around the fulcrum as the center. Using the height adjustment tool 2 on the top face 3 of which the device 90 for lifting a heavy object is placed to thereby adjust the installation height makes the action part 93 of the device 90 for lifting a heavy object reach a bottom surface Wb, thus making it possible to lift the heavy object W.

    【課題】脚付き家具や固定脚介護ベッド等の重量物を安全に持ち上げ移動させるために使用する重量物持ち上げ装置の高さ調整具を提供する。【解決手段】重量物Wに接触し持ち上げる作用部93と、力を加えるレバー94と、支点としての回動軸95と、移動用の車輪92とを備え、てこの原理で重量物Wを持ち上げる装置90の、設置高さを調整する高さ調整具2であって、所定の高さHaを有し、上面3に形成された、前記車輪92を固定する車輪留め部5と、上面3の縁部に形成された、前記作用部93の前記支点を中心とした揺動の範囲を広げるための傾斜面7とを有し、前記重量物持ち上げ装置90を上面3に載置し設置高さを調整する高さ調整具2を使用することで、重量物持ち上げ装置90の作用部93が底面Wbに到達し、重量物Wを持ち上げることができるようにした。【選択図】図1
