Abstract
The invention provides a drum-type washing machine having a mounting structure of a vibration isolation damper for improving vibration inhibiting effect. If a mounting angle of each of the isolation dampers (10) supporting a lower part of a water tub (3) is inclined so that an angle to a vertical direction is larger, it is possible to decrease vibration in right and left directions. However, the right and left width of a washing machine case (7) is limited. If each supporting member (13) is fixed to a base part (7a) in a position outside of each vibration isolation supporting leg (12), stability of the washing machine case (7) is decreased. Therefore, a shape and a mounting position of each supporting member (13) are defined so that an outside edge of a fixing face of each supporting member (13) is fixed inside of an outside edge of each vibration isolation supporting leg (12) when the supporting member (13) is fixed to the base part (7a). Thereby, each mounting angle of the vibration isolation damper (10) can be made larger.
