PURPOSE:To make it possible to selectively drive a blower and a water feed pump with a simple mechanism, by coupling a blower fan with a reversible motor, and by coupling the same with the water feed pump through the intermediary of an one-way clutch. CONSTITUTION:A motor 1 is coupled at its one output shaft end 3 with a water feed pump 8 through the intermediary of an one-way clutch 11 and at its the other output shaft end 2 with a blower fan 4. Since this motor 1 is reversible, a control device 12 may select the rotating direction of the motor 1 so that not only both water feed pump 8 and blower fan 4 may be simultaneously driven but also the blower fan 4 be alone driven. Further, when both pump 8 and fan 4 are simultaneously driven, the wind direction of the blower fan 4 is reversed, and therefore, substantially no drive force of the blower fan 4 is required, thereby it is possible to decrease the output power of the motor 1 to a value with which the motor 1 may drive either the pump or the fan alone.
