Further, since the distance between the rotary sleeve 17 and the first guide member 41 is narrow, when the electric wire cord 29 hits the upper end of the first guide member 41, the electric wire cord 29 may bend outward at a small angle. However, since the recess 42 is formed at the upper end of the first guide member 41, it is possible to avoid the possibility that the electric wire cord 29 bends at a small angle.

The present embodiment works as follows.
When assembling the faucet 11, before assembling the spout main body 16 to the body 12, the hose guide 31 is passed through the spout main body 16 from the tip opening or the base end opening of the spout main body 16 and the spout main body 16 is assembled. The electric wire cord 29 and the flexible hose 24 are passed through the spout main body 16 from the tip opening of the water outlet. The sensor unit 26 and the water discharge head 21 are previously attached to the electric wire cord 29 and the flexible hose 24, respectively.

At this time, the flexible hose 24 is inserted inside the holding member 38 near the base end side of the spout main body 16, the electric wire cord 29 is gripped by the grip portion 39 of the holding member 38, and the lock member 40 is held. It is located at the upper end of the member 38. Along with this, the connectors 35 and 36 of the electric wire cord 29 are positioned in the space 37 on the right side of the outer circumference of the hose guide 31 so that the hose guide 31 is positioned in a predetermined direction of the spout main body 16. At the same time, the sensor unit 26 is fitted into the through hole 25 of the spout main body 16.

Then, with the electric wire cord 29 located on the left side of the spout main body 16, the holding member 38 is inserted into the base end portion of the spout main body 16. The electric wire cord 29 is maintained in a slackened state between the sensor unit 26 and the holding member 38 by engaging the holding member 38 and the lock member 40. In this way, as described above, the electric wire cord 29 is located on the right side of the connectors 35 and 36, and the water spout main body 16 circulates around the outer circumference of the hose guide 31 from the positions of the connectors 35 and 36. It is pulled out from the left side of. The electric wire cord 29 is passed through the first to fourth guide members 41, 45 to 47. Therefore, the electric wire cord 29 passes through the first to fourth guide members 41, 45 to 47 on the left side avoiding the lever handle 14 and the valve mechanism operated by the lever handle 14, and is located below them. Connected to the valve and AC adapter.

Then, in this state, the spout main body 16 is assembled to the body 12.
When the water spout 15 is rotated left and right to change its left-right direction, the holding member 38 rotates slightly following the water spout 15, but rotates relative to the water spout 15 to hold a substantially fixed position. Further, at this time, since the electric wire cord 29 is provided with a slack, an unreasonable pulling force does not act on the electric wire cord 29. Since the electric wire cord 29 is gripped by the grip portion 39 of the holding member 38 on the rotary sleeve 17, it is held at the position on the left side of the rotary sleeve 17 without being disturbed. That is, the electric wire cord 29 is held at a fixed position on the left side even when the spout 15 is rotated.

Further, the electric wire cord 29 is prevented from moving downward by engaging with the lock member 40 located directly above the holding member 38.
A hose guide 31 exists between the flexible hose 24 and the wire cord 29. Therefore, when the water discharge head 21 is removed from the tip of the water discharge port main body 16 and pulled out together with the flexible hose 24, or when the drawn water discharge head 21 is fitted into the water discharge port main body 16, the electric wire cord 29 is flexible. The sex hose 24 is not scratched, and the electric wire cord 29 is prevented from being damaged.

In this embodiment, the following effects are obtained.
(1) When assembling the faucet 11, the holding member 38 can hold the electric wire cord 29 on the left side opposite to the lever handle 14 on the right side. Therefore, even if the electric wire cord 29 in the spout main body 16 cannot be seen, the electric wire cord 29 is not twisted or an unreasonable pulling force acts on the cord 29, and the electric wire cord 29 is spouted. It can be wired to a predetermined position inside the main body 16 and connected to the solenoid valve and the AC adapter below the body 12. Since the electric wire cord 29 can be wired without being twisted in this way, deformation of the hose guide 31 due to twisting of the electric wire cord 29 or the like can be suppressed, and the flexible hose 24 can be smoothly taken in and out. Therefore, when assembling the faucet 11, it is not necessary to hold the electric wire cord 29 by hand and assemble the faucet 11, and the faucet 11 can be easily assembled.

(2) Since the electric wire cord 29 can be wired to the left side at the portion of the rotary sleeve 17, an unreasonable force, for example, pulling on the electric wire cord 29 between the first to fourth guide members 41, 45 to 47 on the left side of the body 12 No force acts. That is, the electric wire cord 29 can be held on the left side of the body 12 by the holding member 38 and the first to fourth guide members 41, 45 to 47. Therefore, even if the spout 15 is rotated left and right, the electric wire cord 29 holds the position on the left side, and the electric wire cord 29 is provided with a slack between the holding member 38 and the sensor unit 26. It is possible to prevent a large bending stress from repeatedly acting on the electric wire cord 29, and it is possible to effectively avoid damage to the electric wire cord 29.

(3) In maintenance of the solenoid valve and the AC adapter, the lock member 40 hits the upper end of the holding member 38 even if a pulling force acts on the electric wire cord 29 at the body 12 or a position below the body 12. For this reason, the pull-down movement of the electric wire cord 29 is prevented, and an excessive pulling force is prevented from acting on the connection portion between the electric wire cord 29 and the sensor unit 26 and the connectors 35 and 36, and the connectors 35 and 36 are disconnected. Can be prevented from doing so.

(4) Since the overlapping portion 311 of the hose guide 31 is located on the outer diameter side of the curved region of the hose guide 31, the slit 32 of the hose guide 31 is located on the inner diameter side of the curved region, and the slit 32 is located. The opening width of the hose becomes narrower. Therefore, when the flexible hose 24 is inserted into the hose guide 31, the flexible hose 24 is less likely to be caught in the edge of the slit 32, and the insertion work of the flexible hose 24 becomes easy. ..

(5) Since the connectors 35 and 36 are located on the right side of the hose guide 31 in the space 37 formed by the width end surface 312 of the hose guide 31, the hose guide 31 is pushed and deformed by the connectors 35 and 36. However, the amount of deformation is small. Therefore, the work of inserting the flexible hose 24 into the hose guide 31 can be smoothly performed. On the other hand, when the connectors 35 and 36 are located on the outer diameter side of the curvature region of the hose guide 31 like the sensor unit 26, the connectors 35 and 36 are located at the portion where the radius of curvature of the hose guide 31 is large. To do. Then, in this portion, a force in the direction of swelling toward the inner surface on the outer diameter side of the spout 15 acts on the hose guide 31, and the hose guide 31 is located at the thick and highly rigid overlapping portion 311. A large force is applied to the hose guide 31 in the crushing direction by the 36. Therefore, the hose guide 31 is greatly deformed by the connectors 35 and 36, and it becomes difficult to insert and remove the flexible hose 24.

(6) Even if the rotary sleeve 17 has a small diameter, since the narrow portion 34 is formed at the end of the hose guide 31, the electric wire cord 29 passes through the outside of the narrow portion 34 and the flexible hose 24 It can be passed without difficulty without contacting with. Therefore, it is possible to prevent the electric wire cord 29 from being damaged by the movement of the flexible hose 24 in and out. Further, since it is not necessary to use a thick rotating sleeve 17, it is possible to realize a slim and highly designed faucet 11. Further, since the narrow portion 34 is formed in the hose guide 31, the narrow portion 34 can be easily inserted into the rotary sleeve 17 when assembling the hose guide 31, and the assembly can be easily performed. it can.
