To make a washer light in weight, portable and improved in convenience by opening one end of a pressurizing pipe part at an upper part inside a water tank part and forcedly blowing from another and to the one manually.
A pressurized rubber ball 40 is compressed in the state of closing opening/closing valves 24 and 34 of a jetting pipe part 20 and a pressurizing pipe part 30, ait is passed through a check valve 38 and stored in a receiver tank 50. When the pressurized rubber ball 40 tries to return to original shape with its own elasticity, external air is sucked from a rubber valve 42. Each time the pressurized rubber ball 40 is repeatedly compressed and recovered, much pressure energy is stored in the receiver tank 50. When performing washing, the opening/closing valve 34 of the pressurizing pipe part 30 is opened. The pressurized air stored in the receiver tank 50 is sent through a constant flow valve 36 and the opening/closing valve 34 into a water tank 10. The pressurized air pushes up the water level of washing water W and the washing water W is sent out to the jetting pipe part 20. When the opening/closing valve 34 is opened, the washing water is jetted from a jetting nozzle and a target local part can be washed.
