摘要

To make it possible to perform height control with a smaller force without changing a shape of an adjusting screw.SOLUTION: An adjusting screw 27 for height control, which is provided at a lower part of a refrigerator 1, comprises a groove 31a, in which a minus driver enters, at an upper end thereof. A controlling tool 41 for height control comprises three engaging parts 45 on an inner peripheral side of an annular body part 43, and comprises one holding part 47 on an outer peripheral part of the body part 43. In the state that one of three engaging parts 45 is so made as to enter in the groove 31a, tips of two remaining engaging parts 45 contact an outer peripheral part of the adjusting screw 27. The adjusting 27 is rotated by rotating the controlling tool 41 in this state, whereby a height of the refrigerator 1 can be adjusted.SELECTED DRAWING: Figure 8
