The hydraulic cylinder 17 serving as a shock absorber has a base end between the upper and lower link rods 15 and 16 at a wall 13.
The upper end of the upper link 15 or the folded portion 11 (or the U-shaped steel 14) is pivotally attached at its distal end to the substantially central portion of the U-shaped steel 12 fixed to the U-shaped steel. In addition to the hydraulic cylinder 17, an air cylinder, a compression coil spring, or the like can be used as the shock absorber, and the shock absorber functions as a damper that relaxes and smoothes the elevating operation of the cabinet elevating device.
Note that a configuration is also conceivable in which the spring action of the shock absorber is strengthened to urge the vertically supporting cabinet supporting device to move upward, and the cabinet can be lightened when the cabinet is lifted and moved upward.

As shown in an enlarged view of a main portion of FIG. 1B, a U-shaped steel 12 fixed to a wall 13 is provided with a mounting member 18 made of a material such as plastic or hard rubber.
