PROBLEM TO BE SOLVED: To provide a liquid jetting device capable of shifting a jetting pattern while securing the function of high pressure jetting. SOLUTION: The liquid jetting device includes a body 1 having a pump 2 sucking, pressurizing and pressure-sending the content of a container 20 and is attached to a container port section 21, a connecting member 4 that has an opening A<SB>1</SB>connected to the pump and is fixed to the tip of the body 1, a regulating valve 5 that controls the content from the connecting member 4, and a nozzle 6 that has the opening 6a jetting the content from the regulating valve 5 and is supported by the connecting member 4, wherein the accommodating space S of the regulating valve 5 is formed between the nozzle 6 and connecting member 4 and an intermediate member 7 that is fixed to the connecting member 4 is provided, a projection 7p that is fitted into and is supported by a recess 6n provided on the back side of the nozzle 6 is provided on the intermediate member 7, a plurality of recessed trenches 7g<SB>1</SB>, 7g<SB>2</SB>whose cross-sections are different and which are connected to the space S are formed at intervals in the circumferential direction on the outer peripheral surface of the projection 7p, a plurality of recessed trenches 6g<SB>1</SB>that are connected to the opening 6a are formed on the recess 6n of the nozzle 6, and the nozzle 6 is rotatably supported around the connecting member 4 so as to allow the recess 6g<SB>1</SB>to be communicated with the recessed trenches 7g<SB>1</SB>(7g<SB>2</SB>).
