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. |
