[0015] The grip shaft 1 includes a nozzle portion 2 and a handle portion 7 made of synthetic resin.

[0016] As shown in FIG. 1, the nozzle part 2 has a thin shaft part concentrically connected to the apex of a conical part. It is an integrally molded product with the tip of the thin shaft portion bent at an approximately semi-right angle.

[0017] As shown in Fig. 1, a water channel 3 is provided at the axial center position of the nozzle part 2, and an outlet of the water channel 3 is provided. The mouth is opened on the tip surface of the thin shaft part of the nozzle part 2, and the jet water is applied to the tip of the nozzle part 2. It forms a nozzle 4 from which a stream is ejected. The entrance to waterway 3 is as shown in Figures 1 and 2. In addition, an opening is formed at the end face of a small connecting shaft 5 that protrudes concentrically from the bottom of the conical part of the nozzle part 2. A water supply port 6 communicating with the nozzle 4 is formed at the end of the nozzle portion 2.

[0018] As shown in FIGS. 1, 2, and 3, the handle portion 7 is a cylindrical body, and the tip of the cylindrical body is open. Fit the mouth into the bottom of the conical part of the nozzle part 2, and place the nozzle part 2 concentrically with the tip of the cylindrical body. The housing hole 8 is formed inside the cylindrical body.
