Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power sprayer enabling a pump to certainly sucking water when the pump is actuated again by engaging a tension clutch after disengaging the tension clutch and stopping actuation of the pump, in the power sprayer provided with the tension clutch transmitting power to the pump. SOLUTION: This power sprayer comprises a prime mover installed in a body frame 12, and a pump 22. The power of the prime mover is transmitted to the pump 22 by a belt, and power transmission is switched on/off by the tension clutches K, K1, K2. A bypass passage 212 communicating a discharge side of the pump 22 to the atmospheric air, and an opening/closing valve 214 opening/closing the bypass passage 212 are provided. An electric cylinder 108 is provided, which opens the opening/closing valve 214 when the tension clutches K, K1, K2 are disengaged and closes the opening/closing valve 214 when the tension clutches K, K1, K2 are engaged.
