Here, adjusting pin (8a, 8b) respectively is equipped with in the lower end of regulating leg (6a, 6b), in order to absorb impulsive force and to reduce vibration, regulates pin (8a, 8b) and makes with elastomeric material.

In addition, be equipped with on the position above the wire (5) of the mid portion of the gathering sill (4a, 4b) on outer cage (1) rear wall on the rear wall that an end is fixed on outer cage (1), the other end is connected on the wire (5), can go up the effect of passing through recuperability under the situation that does not have to bear a heavy burden at above-mentioned left and right sides adjusting leg (6a, 6b) wire (5) is upwards spurred, thus the spring (9) that washing machine can not be sunk.

Effect of the present invention with this structure is as described below.

At first, shown in Fig. 2 a, when the rear of washing machine was placed on the ground of level, left side fixed block (7a) is regulated the upper end of leg (6a) to the left side distance was in identical state with right side fixed block (7b) is regulated the upper end of leg (6b) to the right side distance.

And in contrast, when the rear of washing machine was placed on not too on the flat ground surface, automatic horizontal was regulated the effect of just having played.

Promptly shown in Fig. 2 b, if because the ground of the left part among the figure is more higher relatively than the ground of right side part, thereby the adjusting pin (8a) that makes the left side regulate the end of leg (6a) touches ground earlier, and the left side is regulated leg (6a) and can be moved up along left side guide slot (4a) under the effect of the reaction force on the ground that the weight because of washing machine produces so.

And this moment is because leg (6b) is regulated on the interlock effect right side of wire (5) can move down along right side guide slot (4b).

Therefore when washing machine is installed, even the ground on right side is lower than the ground in left side, the adjusting pin (8b) that leg (6b) is regulated on the right side also can touch ground, thus make the left and right sides at the rear of washing machine can not be subjected to ground the left and right sides difference in height influence and be adjusted to horizontal state automatically.

Be that the interlock effect that device of the present invention is regulated leg (6a, 6b) by wire (5), left and right sides fixed block (7a, 7b) and left and right sides has compensated the difference in height on ground, thereby play the effect of the left and right sides, the rear maintenance level that always can make machine when washing machine is installed.

Therefore user or maintenance personal need not to take great energy the level of considering rear washer, and only need the integral body of washing machine is up to the standard, thereby make the installation of machine become very easy by the height of regulating than the adjusting leg (omitting among the figure) of the front of the washing machine that is easier to touch.

On the other hand, because the left and right horizontal that the present invention can regulate rear washer exactly automatically, thereby can realize the integral level of washing machine exactly, and the noise that can reduce the vibration of washing machine thus and produce because of vibration, thus reliability of products improved.

Making under the fitting operation situation of difficult because of the volume of machine is big, weight is heavier particularly, or be not easy because of the space of installing is little to touch under the situation at rear portion of washing machine that effect of the present invention is more obvious.
