the rotation speed regardless of the rotation range moreover the leg pad of metal or plastic is liable to cause slipping of the washing machine because the metal or plastic has low friction with the floor on which the washing machine is installed in a case of the butyl rubber since the butyl rubber has a resonance range in a low rotation speed range of the washing machine it is required that the washing machine is controlled to pass the resonance range quickly and the leg pad of the butyl rubber is liable to cause walking of the washing machine in the low rotation speed range even though the walking is comparatively rare in a high rotation speed range as a result of study on the material of the leg pad for solving above problems the inventor finds out that use of a block copolymer of hard blocks and soft blocks is very effective as the material of the leg pad that is as illustrated in fig6 the inventor finds out that the leg pad is preferably formed of a copolymer in which the hard blocks hs and the soft blocks ss make a net form because the use of the leg pad of the copolymer of the hard blocks hs and.
