摘要： PROBLEM TO BE SOLVED: To provide a compact, low-vibration, and low-noise drum washing machine.
SOLUTION: A damper for supporting a water tub in a washing machine casing from below includes: a cylinder; oil in a space provided in the cylinder; a piston which is provided at the end of a rod, moves in the cylinder where the oil is sealed in and has a plurality of small holes; a flange provided at the rod and leaving a downward distance with respect to the piston; and a valve movable between the piston and the flange. The piston has at least one hole to pass the oil even if the valve contacts the piston and a notch provided in the radial direction and at the lower part of the piston and at the position of the hole. When the damper extends/contracts a length larger than a predetermined length by the vibration of the water tub in a resonance range during dehydration, damping characteristics are switched so that the damping force increases only when the water tub is moving upward.
