<p>PROBLEM TO BE SOLVED: To provide a high pressure washer which prevents a user and a periphery wider than expected from getting wet even when the user releases connection between a water source side joint and a water absorption joint without conducting a predetermined procedure.SOLUTION: A high pressure washer includes: a pump mechanism 21; a water absorption joint 16 which may connect with a water source side joint connected with an external water source; and a water absorption path connecting the water absorption joint 16 with the pump mechanism 21. A back flow buffer device 70 which weakens water flow flowing from the pump mechanism 21 to the water absorption joint 16 is disposed at the water absorption joint 16 side of the water absorption path.</p> |
