A drum-type washing machine includes left and right side plates (8) formed of steel plates, the side plates (8) defining side surfaces of an outer case (1), a front cover (5) provided with an openable and closable door (4), the front cover (5) defining a front surface of the outer case (1), an upper cover (2) defining an upper surface of the outer case (1), a water tank (12) oscillatably arranged in the outer case (1), and a rotary drum (11) axially supported in the water tank (12), wherein a plurality of concave portions (9) are formed on the left and right side plates (8), and the concave portion (9) closer to the front surface of the outer case (1) as a door side has an arc shape with a larger curvature. Thus, rigidity of the side plates (8) in the up and down direction and the left and right direction is increased, so that vibration at the time of spin-drying is reduced. |
