PROBLEM TO BE SOLVED: To put the lower limit of a controllable range in the delivery pressure of a high-pressure water at a lower setting.SOLUTION: This high-pressure washer 10 includes: a washer body 11 that generates a high-pressure water by driving a pump 41 by a driving source 32 and pressurizing a supplied water by pump 41; a delivery apparatus 21 that is connected through the washer body 11 and a hose and delivers the high-pressure water sent from the washer body 11; a setting section 15 that sets a revolution speed of the driving source 32; and controlling sections 35, 36 that perform drive-control on the driving source 32 to aim at the revolution speed set by the setting section 15. Then, the controlling sections 35, 36 obtain the revolution speeds at a detecting section 35 of revolution speed that detects the revolution speed of the driving source 32 and the revolution speed of the driving source 32 detected by the detecting section 35 of revolution speed, and has a control circuit 36 that transmits a drive controlling signal to the driving source 32 to allow the driving source 32 to keep the revolution speed set by the setting section 15. |
