PROBLEM TO BE SOLVED: To absorb swing energy by kinetic energy by rolling rollers fitted in the guide grooves of the upper and lower bases relatively back and forth and laterally against the load of housed utensils or the like and repeating the rising motion, when the lower base installed on a floor face swings in the two- dimentional direction of the fore and aft and right and left sides. SOLUTION: When a lateral swing occurs, a lower base frame 3 and a transfer frame body swing together with a floor face. But in an upper base frame 3, rollers 6 fitted to guide grooves 8 transfer in the right and left direction to repeat the rising motion. In this time, the kinetic energy moving up the a show case 1 absorbs the swing energy. When a before and behind swing occurs, the lower side tease frame 3 swings together with the floor face. But respective rollers 6 fitted in the guide grooves 9 rolls back and forth and repeats a rising motion. Thereby, the transfer frame body, the upper side base frame 3, and the show case 1 as well repeat the rising motion. The swing energy is absorbed by the kinetic energy generated in this time.
