And a ring-shaped flange 14 formed between the large-diameter portion 12 and the small-diameter portion 13 so as to have a larger diameter than the large-diameter portion 12, and the flange 14 is a wall of the shower head 1. 8 has a larger diameter than the insertion hole 9 formed in the hole 8, and thus cannot be inserted through the insertion hole 9. However, since the small-diameter portion 13 is formed to have a smaller diameter than the insertion hole 9, the insertion hole 9 is inserted through the insertion hole 9. Can face the flow path 2. A locking groove 13a and an annular groove 13b are formed in an annular shape on the outer peripheral surface of the substantially distal end of the small diameter portion 13 from the distal end, and a sealing material 13c for preventing water leakage is attached to the annular groove 13b. A ring 16 (to be described later) can be engaged with the locking groove 13 a facing the flow path 2 from the opening 3 of the shower head 1.
[0010]
The ring 16 is formed of an elastic material and bent into a substantially U shape, and has an outer diameter larger than the insertion hole 9 formed in the wall 8 of the shower head 1 as shown in FIG. If the ring 16 is engaged with the locking groove 13 a of the connecting member 10, the connecting member 10 is connected to the shower head 1, and the hose 17 does not come out of the shower head 1.
[0011]
The hose 17 is sandwiched between an inner synthetic resin hose 17a and a metal hose 17b which covers the synthetic resin hose 17a and has a large number of spiral concave and convex grooves 17c formed on the outer peripheral surface at regular intervals. A groove 18 a is formed in the outer peripheral surface of the fixed cylinder 18, and a retaining ring 19 in which a notch is formed is elastically attached to the groove 18 a so as to protrude from the outer peripheral surface of the fixed cylinder 18. Since the connecting member 10 has a groove 15 in which the retaining ring 19 is elastically mounted on the inner peripheral surface of the passage 11 formed on the inner periphery of the large-diameter portion 12, the tip of the hose 17 is When inserted into the passage 11 of the connecting member 10, the retaining ring 19 is elastically mounted in the groove 15, so that the connecting member 10 is rotatable with respect to the hose 17 and is not easily detached.
[0012]
In order to connect the hose 17 having the connecting member 10 connected to the tip to the shower head 1, the connecting member 10 is first inserted into the connecting hole 6 of the shower head 1 as shown in FIG. 2. Then, the flange portion 14 of the connection member 10 contacts the cylindrical member 7, and the small diameter portion 13 passes through the insertion hole 9 of the wall 8 and faces the flow path 2.
[0013]
Next, when the ring 16 is inserted from the opening 3 of the shower head 1 toward the flow path 2 and is elastically engaged with the locking groove 13 a of the connection member 10, the connection member 10 is connected to the shower head 1. .
