Next, a method for assembling the shower head 11 configured as described above will be described.
As apparent from FIGS. 2 and 10, when assembling the shower head 11, the partition member 18 is inserted into the head portion 22 from the opening 23, and the connecting tube 49 is inserted into the grip portion 19. At this time, as shown in FIG. 10, the partition member 18 is displaced downward from the original built-in fixed position in the head portion 22 and is positioned in the enlarged diameter portion 26 of the opening 23, as shown in FIG. 7. The stopper 50 is spaced downward from the outer peripheral surface of the female screw cylinder 25A indicated by a two-dot chain line. Further, as shown in FIG. 10, the flat surface 62 of the inner pipe 21 is separated from the flat surface 59 of the grip portion 19 to the lower side outside the grip portion 19 at this displacement position.

  On the other hand, the inner pipe 21 is inserted from the lower end opening of the grip portion 19, and the upper male screw 54 is screwed into the female screw 55 of the connecting pipe 49 of the partition member 18. At this time, since the partition member 18 is displaced downward from the built-in fixed position in the opening 23, the flange 61 of the inner pipe 21 is exposed to the outside below the grip portion 19. Therefore, in this state, the inner pipe 21 can be connected to the connecting pipe 49 by screwing the male screw 54 of the inner pipe 21 into the female screw 55 of the connecting pipe 49 until the projections 56 and 57 come into contact with each other. In this way, the flat surface 62 at the lower end of the inner pipe 21 is vertically opposed to the flat surface 59 at the lower end of the grip portion 19 below.

  Next, the partition member 18 connected to the inner pipe 21 is moved upward in the opening 23, and as shown in FIG. 7, the stopper 50 is brought into contact with the lower part of the outer peripheral surface of the female screw cylinder 25B indicated by the solid line.

  In the shower head 11 configured as described above, water or hot water from the water supply hose 12 reaches the discharge chamber 20 through the inner pipe 21 and is discharged from the discharge holes 15 and 16 as a shower. Therefore, water or hot water does not pass through the plated housing 14, and even if the plating is peeled off, the peeling plating does not clog the discharge holes 15 and 16.

Therefore, this embodiment has the following effects.
(1) The flow path member is divided into the partition member 18 and the inner pipe 21, and the grip portion 19 and the inner pipe 21 are formed with a rotation preventing portion and a positioning portion made of flat surfaces 59 and 62 that are in contact with each other. The holding part 19 and the inner pipe 21 can be fixed in a positioned state, and it is not necessary to use separate parts such as pins and clips in their assembly. Therefore, the number of parts can be reduced.

  (2) Since pins, clips, and the like are not used, there is no need to provide a hole for attaching them outside the grip portion 19. For this reason, the appearance of the shower head 11 is improved, and a member for concealing pins, clips and the like is also unnecessary.

  (3) Since it is not necessary to secure a mounting space for pins, clips, etc., the shower head 11 is not formed with a bulging portion for mounting pins, clips, etc., and the design of the shower head 11 Can be prevented from decreasing.

(4) Since the rotation preventing portion of the inner pipe 21 is the flat surfaces 59 and 62 formed on both the inner pipe 21 and the grip portion 19, the configuration is simple.
(5) The partition member 18 constituting the flow path member is movable from the built-in fixed position to the displacement position, and the plane 62 of the inner pipe 21 connected to the partition member 18 at the displacement position is the plane of the grip portion 19. 59. Therefore, the inner pipe 21 can be rotated, and the inner pipe 21 can be connected to the partition member 18 without hindrance.

  (6) When the inner pipe 21 reaches a predetermined assembly position with respect to the partition member 18 in a state where the lower end of the inner pipe 21 is displaced downward from the lower end of the grip portion 19, the partition member 18 and the inner pipe 21 The protrusions 56 and 57 come into contact with each other to define the positional relationship between the partition member 18 and the inner pipe 21, and the plane 62 of the inner pipe 21 is disposed at a position corresponding to the plane 59 of the grip portion 19. Therefore, in this state, if the partition member 18 and the inner pipe 21 are moved upward from the displacement position, the flat surfaces 59 and 62 come into contact with each other, and the inner pipe 21 and the partition member 18 are positioned at the built-in fixed position. Therefore, the partition member 18 and the inner pipe 21 can be easily positioned and fixed at the fixed positions.

  (7) Around the screw insertion hole 45 of the partition member 18, there is provided a stopper 50 capable of contacting the outer periphery of the female screw cylinder 25 of the head portion 22, and the partition member 18 is moved from the downward displacement position to the upper fixed position. When moved, the stopper 50 is regulated in position by the female screw cylinder 25. Therefore, the partition member 18 can be easily assembled to the head portion 22 with the screw 46 at this position.
