A washing machine not only may properly suppress vibration of an outer drum, but also may be easier to assemble due to a simple structure, thereby realizing reduction of the manufacturing cost. A washing machine including elastic supporting units (5) for elastically supporting the outer drum (3) to a main body (2) includes: a plurality of extension springs (6) to (6) arranged between the outer drum (3) and the main body (2) and capable of applying a counteracting force to the outer drum (3) to enable the outer drum (3) to return to an original position when a displacement of the outer drum (3) is transmitted to the extension springs; and a displacement transmission unit (8) capable of transmitting the displacement of the outer drum (3) to the extension springs (6) to (6) only when the displacement of the outer drum (3) is larger than a specified value. The extension springs (6) have a preset initial tension (Fp).
