The device (1) includes: a main body (12) mounted on an inner circumferential face (5E) of the washing tank (5); an intake port (13) provided at a lower end portion (12C) of the main body (12); a waterway (15); and an exhaust port (14) provided on a surface (12B) of an upper end portion (12D) of the main body (12). Water introduced by the intake port (13) into the washing tank (5) is guided through the waterway (15) so as to be exhausted from the exhaust port (14) and splashed onto laundry (S) in the washing tank (5). The exhaust port (14) is relatively long in a circumferential direction Y of the inner circumferential face (5E), a top-to-bottom width of the exhaust port (14) in the middle is narrower than that a
