The raised height is formed to change. That is, referring to FIG. 1, since the separation distance d1 between the laundry access hole 11 and the tub body 21 is gradually increased toward the upper side of the tub 20, the tub inlet 22 is increased. Is formed so that the protrusion height gradually increases toward the upper side of the tub.

Therefore, since the height of the protrusion is gradually increased toward the tub inlet 22 toward the upper side of the tub 20, the separation distance d2 between the front of the tub inlet 22 and the laundry access hole 11. Becomes the same. In addition, the tub opening hole 22a formed in front of the tub inlet portion 22 is formed to be parallel to the laundry access hole 11, and the tub opening hole 22a and the laundry access hole 11 are formed. The virtual center line c is formed to be positioned substantially in a straight line.

A drum opening hole 30a is formed at the front of the drum 30 to face the laundry access hole 11, and the motor 14 is connected to the rear of the drum 30 by a rotation shaft 15. .
