A drum type washing machine having a suspension supporting a water tub in a vibration isolated manner and including a cylinder, a magnetic field generator fixed in the cylinder, a pair of magnetic members located at both axial sides of the field generator respectively, a smart fluid including a magneto-rheological fluid retained on an inner surface of the generator, a sealing member which is fixed in the cylinder so as to be located below the generator to prevent leakage of the smart fluid so that the smart fluid is retained, and a shaft which is supported so as to be axially reciprocable relatively along the generator, magnetic members, smart fluid, and sealing member such that reciprocation of the shaft does not substantially displace the smart fluid. The generator generates a magnetic circuit including the cylinder and the shaft. |
