That is, in FIGS. 16A and 16B, 38 is a mesh, 52 is a cylindrical member, 54 is an operation ring, 56 is a shaft portion, 58 is a snap ring, and 88 is a spacer member.
- the method of using the water discharging device 28 is the same as that of the above-described embodiment.
- Figs. 19 to 22 show a sixth embodiment of the present invention.
- the water spouting device 28C also has a configuration similar to that of the water spouting device 28 in Fig. 112, and members having the same configuration are denoted by the same reference numerals, and the configuration is slightly different. Members having the same function are denoted by reference numerals with "C" attached. [0118] In this water discharging device 28C, the lever 400 is attached to the operation ring 54C.
- the lever 400 includes an annular base ring 401 that is fitted coaxially to the operation ring 54C, a fixing ring 402 that fixes the base ring 401 to the operation ring 54C, and a side from the base ring 401. And a lever body 403 extending in the radial direction.
- a serration 404 is formed on the inner peripheral surface of the base ring 401.
- a plurality of protrusions 405 engaging with the serrations 404 are provided at intervals in the circumferential direction.
- a protruding step 406 projecting inside the base ring 401 is formed on the upper end side of the serration 404.
- a female screw 407 is formed on the inner peripheral surface on the lower end side of the base ring 401.
- a male screw 408 (Fig. 21) screwed to the female screw 407 is provided on the outer peripheral surface of the fixing ring 402.
- the diameter of the hole inside the fixing ring 402 is slightly larger than the outside diameter of the cylindrical member 52C inside the operation ring 54C.
- the lever main body 403 is a substantially semicircular flat plate, but the shape of the lever main body is not limited to this.
- the lever body may be, for example, a rod-shaped ring.
- the base ring 401 is externally fitted to the operation ring 54C by an upward force while the ridge 405 is engaged with the serration 404. Thereafter, the fixing ring 402 is screwed into the female screw 407. At this time, the convex step portion 406 comes into contact with the upper end surface of the convex ridge 405 from above, and the fixing ring 402 overlaps the lower end surface of the operation ring 54C from below. As a result, the base ring 401 is fixed to the operation ring 54C, and the lever 400 and the operation ring 54C are integrated.
- the inverted tapered portion 82 inside the lower end of the cylindrical member 52C has the outer peripheral portion of the water spray plate 60.
- the lower end surface 410 is configured to be located above the lower surface of the sprinkling plate 60. That is, at the time of shower water discharge, the tubular member 52C retreats from the periphery of the water spray plate 60, and the lower portion of the water spray plate 60 projects downward from the lower end surface 410 of the tubular member 52C.
- the water discharging device 28C is connected to the opening (water discharging port) 30C of the hand-held (grip-type) water discharging head 26C via the cylindrical joint 420.
- a female screw is provided on the lower inner peripheral surface of the tubular joint 420.
- a male screw on the upper outer peripheral surface of the joint body 32 is screwed into the female screw.
- An outwardly facing flange 421 protrudes radially from the outer peripheral surface of the lower part of the tubular joint 420.
- an inward flange portion 84 on the upper end side of the operation ring 54C is rotatably held between the flange portion 421 and an outward flange portion 86 in the middle of the joint body 32. I have.
- a ring 422 is mounted on the upper outer peripheral surface of the tubular joint 420. Further, a step is formed at the upper inner peripheral edge of the tubular joint 420, and the mesh 38 is provided so as to be locked to the step.
- a concave portion 423 is provided on the outer peripheral surface at an intermediate portion of the tubular joint 420 to which a lock screw 26a for fixing the tubular joint 420 to the water discharge head 26C is engaged.
- a female screw hole 26b into which the lock screw 26a is screwed is provided on a side surface of the water discharge head 26C.
- the female screw hole 26b penetrates the side surface of the water discharge head 26C and communicates with the inside of the opening 30C.
- the lever 400 is provided on the operation ring 54C, so that a finger or a hand is put on the lever 400 to push or pull the lever 400 back and forth.
- the operation ring 54C can be easily rotated with relatively little effort.
- the tubular member 52C retreats from the periphery of the sprinkling plate 60, and the lower part of the sprinkling plate 60 moves downward from the lower end surface 410 of the tubular member 52C. Since it protrudes, the water discharged from the water sprinkling holes 62 on the lower surface of the water sprinkling plate 60 is prevented from hitting the cylindrical member 52C and the like and diverging around.
