To arbitrarily provide damper force for reducing vibrations at the time of resonant point passage in the case of starting a machine and to make the machine compact at low cost concerning a vibration proofing device for washing and dehydrating machine for elasticity supporting an outer tub for receiving water at the time of dehydration.

An outer tub 15 for receiving water at the time of dehydration while being positioned outside the washing and dehydrating machine is elasticity supported from four corners of a main body 20 of washing machine by suspensions 21. Concerning the suspension 21, a spring supporting plate 24 having a frictional member 26 at the outer periphery is fitted to the lower part of a hanging bar 22, the spring supporting plate 24 is covered with a cylindrical spring presser 23 inserted through this hanging bar 22, both the ends of a loop- shaped wire having elasticity are bent inside, and a loop-shaped spring 28 overlapping these bent parts is fitted to the inner periphery of the spring supporting plate 24.
