PROBLEM TO BE SOLVED: To reduce noise in a liquid type massage in which liquid for jetting inside a main body housing has a free surface. SOLUTION: A user M is supported on a supporting sheet 2 covering the upper opening 1a of the main body housing 1. Inside the main body housing 1, the liquid for jetting is stored at a liquid level having the free surface. By a pump 14, the liquid for jetting is jetted from a jetting nozzle 12A and made to collide with the supporting sheet 2 and massage is performed. The jetting nozzle 12A is provided with a center nozzle 18A for jetting the liquid for jetting to produce high speed jetted liquid for massage and a plurality of peripheral nozzles 19A disposed around the center nozzle 18A and functioning for noise reduction by jetting the liquid for jetting at low speed. A plurality of jetting ports of the peripheral nozzles can be positioned at roughly equal intervals around the center nozzle (Figure 9 and Figure 14) or can be set in an annular shape continuously extended over the entire length in a peripheral direction of the center nozzle (Figure 13).
