Abstract: An inner peripheral water entry reducing portion and an outer peripheral water entry reducing portion are provided. The inner peripheral water entry reducing portion includes an inner peripheral wall portion surrounding an output shaft. The outer peripheral water entry reducing portion includes an outer peripheral wall portion surrounding the inner peripheral wall portion. At least one inner peripheral opening of the inner peripheral water entry reducing portion and at least one outer peripheral opening of the outer peripheral water entry reducing portion are prevented from overlapping with each other in a circumferential direction of the output shaft.

Abstract: A drain hose (1) includes a drain hose body (10) and a hard member (20). The hard member (20) includes a notch (22) and hooks (21). The drain hose body (10) includes a protruding portion (14) provided to a part, of an outer periphery of the drain hose body (10), to which the hard member (20) is attached. The protruding portion (14) protrudes to be positioned in the notch (22), and, when force is applied to the drain hose body (10) in a direction to pull the drain hose body (10) from a through hole (P1), depresses edge portions (22a) of the notch (22) in a direction to expand the hard member (20) in diameter.

Abstract: In a casing 11, a rear guide 23 is formed above a cylindrical impeller 13 and a stabilizer 24 is formed below the impeller. A minimum gap dimension between the cylindrical impeller 13 and the stabilizer 24 on the outlet port 17 side has a value of 14% to 24% of the outer diameter of the cylindrical impeller 13. An angle between a straight line connecting the center of rotation of the cylindrical impeller 13 and a minimum gap position on the outlet port 17 side of the stabilizer 24 and the horizontal plane has a value of 38° to 43°. A minimum gap dimension between the cylindrical impeller 13 and the stabilizer 24 on the inlet port 16 side has a value of not smaller than 7% of the outer diameter of the cylindrical impeller 13. An angle between a straight line connecting the center of rotation of the cylindrical impeller 13 and a minimum gap position on the inlet port 16 side of the stabilizer 24 and the vertical plane has a value of 11° to 15°.
