When hot water is supplied to the rear of each stroke chamber 24, 25 through the pipes 31, 32, the water pressure causes each nozzle body 16, 17 to slide forward against the spring force of the coil springs 44, 45. The tips of the nozzle bodies 16 and 17 protrude to the front of the cylinder case 15, and hot water is jetted out from each of the jet holes 34 and 35 (see chain lines in FIG. 4). It retreats into the cylinder case 15 due to the spring force. If the nozzle bodies 16 and 17 are housed in the cylinder case 15 and the jetting part 9 is assembled in this way, the jetting part 9 can be made into a compact unit, easy to handle, and has a solid structure. Further, as described above, when the nozzle bodies 16, 17 are projected, if the coil springs 44, 45 are compressed and housed in the tube bodies 42, 43 of the same length, both coil springs 44, 45 can be placed in the same length. By using springs with the same spring properties and free lengths, both nozzle bodies 16 and 17 can have the same water pressure resistance during hot water supply, and both nozzle bodies 16 and 17 can be stably projected and submerged in the same way. can.
