This research deals with analysis and design of nozzle driving mechanism for chair-type water jet massage machine intended to give massage function by water jet that moves around the back of users. First the kinematic structure of nozzle moving mechanism is developed to allow 2 degree of freedom motion, and then the hydraulic components for pressure generation including pump, hose, nozzle, connectors are chosen, and the pressure distribution by the nozzle is experimentally measured as functions of distance and nozzle shape. The prototype of the water pressure massage machine is developed to demonstrate the validity of the completely new type of machine.
