Summary of the Invention

Problems to be Solved by the Invention

[0004] In the technology described in Patent Document 1 above, the shape of the joint portion of the water discharge pipe with respect to the faucet body is complicated, and it is necessary to perform cutting processing after molding by injection molding, and further structural changes are required to suppress the manufacturing cost.

[0005] In view of such problems, an object of the present invention is to provide a faucet with a low manufacturing cost structure in a faucet that discharges water laterally from the faucet body.

Means for Solving the Problems

[0006] The first invention of the present invention is a faucet that discharges water laterally from a faucet body. The faucet body includes a temperature control valve unit that is attached to an installation surface and mixes hot water and water supplied from below the installation surface and discharges them as discharged water, and a substantially cylindrical water discharge unit that discharges the discharged water supplied from the temperature control valve unit laterally of the temperature control valve unit. The temperature control valve unit has a partition wall portion that axially partitions an inner cylinder portion of a substantially cylindrical casing portion. A first mounting hole that penetrates between an outer cylinder surface and an inner cylinder surface through which the water discharge portion passes is provided in the casing portion below the partition wall portion. One end side of the water discharge portion is inserted into the first mounting hole and is connected by being fastened to the partition wall portion with bolts in a state where the axial directions thereof intersect with respect to the casing portion. The water discharge portion is formed by combining a first component on the axial tip side and a second component on the axial base side. A groove portion for arranging an O-ring for maintaining a watertight state between the outer peripheral surface of the water discharge portion and the inner peripheral edge portion of the first mounting hole of the casing portion is formed at the joint of the first component and the second component.

[0007] According to the first invention, since the casing portion of the temperature control valve unit and the water discharge portion of the faucet body are each formed in a substantially cylindrical shape, they can be manufactured by injection molding, cutting, etc. without using complicated processes such as casting. Further, the attachment of the water discharge portion to the temperature control valve unit is performed by inserting one end side of the water discharge portion into the first mounting hole and fastening a part thereof to the partition wall portion with bolts in a state where the axial directions thereof intersect with respect to the casing portion, so that a faucet with a low manufacturing cost structure can be provided. Further, since the groove for arranging the O-ring, which is complicated to process if the water discharge portion is formed of a single part, is configured to be formed at the joint of the first component and the second component when the second component is combined with the first component, the manufacture of the water discharge portion is easy. Here, the lateral side of the temperature control valve unit means the direction toward the radially outer side in the casing portion of the temperature control valve unit.

[0008] The second invention of the present invention is, in the above first invention, a reduced-diameter portion having an outer diameter set smaller than that of the general portion is formed on the one end side of the water discharge portion, and the reduced-diameter portion is inserted into the first mounting hole, and a vertical wall surface connecting the outer surface of the general portion and the outer surface of the reduced-diameter portion abuts against the outer cylindrical surface around the first mounting hole in the casing portion, and the water discharge portion is attached to the casing portion.

[0009] According to the second invention, since the water discharge portion is attached to the casing portion with the reduced-diameter portion inserted into the first mounting hole and the vertical wall surface abutting against the outer cylindrical surface around the first mounting hole in the casing portion, the water discharge portion is less likely to swing in a direction perpendicular to the axial direction with respect to the casing portion and is more firmly connected.

[0010] The third invention of the present invention is, in the above second invention, an auxiliary member having a substantially cylindrical shape and having an outer diameter surface and an inner diameter surface is inserted into the inner cylinder portion of the casing portion from below, and the partition portion is fixed and supported on the upper surface portion of the auxiliary member whose outer diameter surface is in sliding contact with the inner cylinder surface and is inserted, and a second mounting hole having the same axis and the same diameter as the first mounting hole is provided in the auxiliary member so as to penetrate between the outer diameter surface and the inner diameter surface, and a bolt hole for passing the bolt is provided in a part of the inner peripheral edge portion of the second mounting hole in the auxiliary member.

[0011] According to the third invention, in a state where the partition portion is supported by the auxiliary member, the water discharge portion having one end side inserted into the first mounting hole and the second mounting hole is fastened and fixed to the partition portion via the auxiliary member by a bolt, so that the water discharge portion is firmly attached to the temperature control valve portion.

[0012] The fourth invention of the present invention is, in the above third invention, a locked portion and a locking portion for preventing the second component from moving in the axial direction of the second component with respect to the auxiliary member when the auxiliary member and the second component are assembled are provided on the auxiliary member and the second component, respectively.

[0013] According to the fourth invention, since the second component is assembled in a state where it is suppressed from moving in the axial direction of the second component with respect to the temperature control valve unit, it is possible to suppress play when an axial force is applied to the water discharge unit.

[0014] A fifth invention of the present invention is characterized in that, in any one of the first invention to the fourth invention, the first component and the second component are each provided with an engaging portion and an engaged portion for preventing relative rotation in the circumferential direction when combined.

[0015] According to the fifth invention, since the first component and the second component are combined in a state where relative rotation in the circumferential direction is suppressed, it is possible to suppress play when a force perpendicular to the axial direction is applied to the water discharge unit.

[0017] The configuration of the faucet 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 9. In the following description, the description of directions is based on the up-down, front-back, left-right directions shown in each figure.

[0018] As shown in FIGS. 1 and 2, the faucet 1 according to the present embodiment is a hot and cold water mixing faucet installed on the top plate M of a sink or a washbasin. The faucet 1 has a faucet body 2 that mixes hot water and cold water supplied from below the top plate M and discharges the mixture forward, and a pull-out discharge pipe 3 that is detachably attached to the front of the faucet body 2 so as to be pulled forward. The pull-out discharge pipe 3 has a cylindrical shape, and discharges the hot and cold water, which is the discharged water supplied from the faucet body 2 through the flexible pipe 4c1, from the front discharge port 3a in a direction perpendicular to the axis of the cylinder. The flexible pipe 4c1 is a pipe that can be freely bent and stretched, and is connected to the pull-out discharge pipe 3 through a connection member 4c2 while maintaining a watertight state. Since the pull-out discharge pipe 3 is connected to the faucet body 2 and the flexible pipe 4c1, the discharge direction of the hot and cold water can be freely changed by holding and operating it by hand. Here, the top plate M corresponds to the "installation surface" in the claims.

[0019] As shown in FIGS. 1 to 4, the faucet body 2 has a temperature control valve unit 10 that mixes the supplied hot water and cold water to adjust the temperature of the discharged water and a function of adjusting the amount of the discharged water, and a discharge unit 20 that is connected to the front of the temperature control valve unit 10 and directs the flexible pipe 4c1 forward.

[0020] The temperature control valve unit 10 has a casing unit 11 having a substantially cylindrical shape, a partition unit 12 that axially partitions the inner cylinder unit of the casing unit 11, a cartridge 13 disposed above the partition unit 12, an operation handle 14 that operates the cartridge 13, and a substantially cylindrical auxiliary member 15 disposed below the inner cylinder unit of the casing unit 11.

[0021] As shown in FIGS. 2 to 6, the casing portion 11 is formed in a substantially cylindrical shape by injection molding of resin, and is formed so as to be fixed to the top plate M in a state where the axis A1 of the cylinder is perpendicular to the top plate M. Note that the casing portion 11 may be formed by machining a metal. The casing portion 11 has an outer cylindrical surface 11S1 and an inner cylindrical surface 11S2. The inner cylindrical surface 11S2 includes an upper inner cylindrical portion 11b formed from a slightly upper position in the central portion in the vertical direction of the casing portion 11 to the upper end surface portion, and an inner diameter smaller than that of the upper inner cylindrical portion 11b formed from the lower end portion of the upper inner cylindrical portion 11b to the lower end portion of the casing portion 11. A lower inner cylindrical portion 11c. The upper inner cylindrical portion 11b is formed to have an inner diameter capable of attaching a cover member 16 that covers the upper end surface portion of the casing portion 11. Specifically, the cover member 16 has a cover portion 16a on the upper end portion side and a cylindrical attachment portion 16b on the lower end portion side, and the inner diameter of the upper inner cylindrical portion 11b is slightly larger than the outer diameter of the attachment portion 16b. The inner diameter of the attachment portion 16b is slightly larger than the outer diameter of the cartridge 13. A female screw 16b1 is formed in the inner diameter portion on the lower end portion side of the attachment portion 16b. The lower inner cylindrical portion 11c is formed so that an auxiliary member 15 can be attached from below. Specifically, when the auxiliary member 15 is inserted into the lower inner cylindrical portion 11c of the casing portion 11 on the lower end portion side of the lower inner cylindrical portion 11c, it is provided at a position slightly below the central portion in the vertical direction of the auxiliary member 15 and has a diameter enlarged in two steps. A fitting portion 11c1 is provided that fits with the enlarged diameter portion 15c to stop the upward movement of the auxiliary member 15. On the upper front side of the lower inner cylindrical portion 11c in the casing portion 11, a water discharge portion attachment hole 11d that penetrates from the outer cylindrical surface 11S1 to the inner cylindrical surface 11S2 for attaching the water discharge portion 20 to the casing portion 11 is provided. The water discharge portion attachment hole 11d is a hole for inserting the cylindrical water discharge portion 20, and the water discharge portion 20 is formed in a shape such that the end portion on the side opposite to the casing portion 11 faces forward and upward, and the axis A2 of the water discharge portion 20 forms an angle of about 70 degrees with respect to the axis A1 of the casing portion 11. The casing portion 11 may be manufactured by machining or injection molding of resin. Here, the water discharge portion attachment hole 11d corresponds to the "first attachment hole" in the claims. Further, the upper inner cylindrical portion 11b and the lower inner cylindrical portion 11c correspond to the "inner cylindrical portion" in the claims.

[0022] As shown in FIGS. 2, 5, and 6, a partition wall portion 12 extending in the radial direction perpendicular to the axis A1 is disposed at an upper and lower position straddling the upper inner cylinder portion 11b and the lower inner cylinder portion 11c in the casing portion 11, and the inside of the casing portion 11 is divided into upper and lower parts. The partition wall portion 12 is substantially disc-shaped, and has a first through hole 12a1 for connecting the water supply pipe 4a in a watertight state, a second through hole 12a2 for connecting the hot water supply pipe 4b in a watertight state, and a third through hole 12a3 for connecting the hot and cold water discharge pipe 4c in a watertight state, which are respectively provided so as to penetrate in the vertical direction. Further, the partition wall portion 12 is provided with a bottomed screw hole 12a4 having an internal thread cut for tightening the large bolt 17 on the front side with the opening facing downward, and a pair of left and right screw holes (not shown) having internal threads cut for tightening the small bolt 18 on the rear side. The pair of bottomed holes 12a5 shown in FIG. 2 are for positioning to prevent relative rotation of the cartridge 13 with respect to the partition wall portion 12. The partition wall portion 12 is attached in a state of being in close contact with the upper surface portion 15a1 of the auxiliary member 15. The specific attachment method will be described later. An external thread 12b is cut on the upper outer peripheral portion of the partition wall portion 12. The external thread 12b is engaged with the internal thread 16b1 of the cover member 16.

[0023] As shown in FIGS. 2, 4 to 6, the cartridge 13 is a component that mixes the supplied hot water and water by relatively moving a movable disk (not shown) with respect to a fixed disk (not shown) disposed in a cylindrical casing 13a by operating an operation portion 13b, and functions to adjust the temperature of the discharged water and the amount of the discharged water. The cartridge 13 is disposed in a state where the lower surface of the casing 13a is in close contact with the upper surface of the partition wall portion 12, thereby connecting the first through hole 12a1 and the second through hole 12a2 to the third through hole 12a3 to perform its function.

[0024] As shown in FIGS. 1 and 2, the operation handle 14 has a columnar base portion 14a having the same diameter as the casing portion 11, and a plate-like grip portion 14b extending radially outward from the upper end portion of the base portion 14a. When the operation handle 14 is attached from above to the casing portion 11 to which the cover member 16 is attached, the lower end portion of the base portion 14a fits into the operation portion 13b of the cartridge 13. Then, by rotating the grip portion 14b left and right, the operation portion 13b is rotated left and right to change the mixing ratio of hot water and cold water, and by rotating the grip portion 14b up and down, the operation portion 13b is rotated up and down to adjust the amount of discharged water.

[0025] As shown in FIGS. 2 and 5 to 7, the water discharging portion 20 is formed by combining a substantially cylindrical main portion 21 and a sub-portion 22 attached to the rear side of the main portion 21. The main portion 21 and the sub-portion 22 are formed by injection molding of resin. The main portion 21 has, from the front end portion toward the rear, a front large-diameter portion 21a with a large outer diameter, a middle-diameter portion 21b with an outer diameter smaller than that of the large-diameter portion 21a, and a small-diameter portion 21c with an outer diameter smaller than that of the middle-diameter portion 21b, which are arranged in this order. The outer diameter of the middle-diameter portion 21b is set to be approximately equal to the average of the outer diameter of the large-diameter portion 21a and the outer diameter of the small-diameter portion 21c. The surface connecting the rear end portion of the outer surface of the large-diameter portion 21a and the front end portion of the outer surface of the middle-diameter portion 21b is the first connecting surface 21d, and the surface connecting the rear end portion of the outer surface of the middle-diameter portion 21b and the front end portion of the outer surface of the small-diameter portion 21c is the second connecting surface 21e. The outer diameter of the middle-diameter portion 21b is set to be slightly smaller than the inner diameter of the water discharging portion mounting hole 11d of the casing portion 11. When the rear end portion (the end portion on the side attached to the casing portion 11) of the water discharging portion 20 is inserted into the water discharging portion mounting hole 11d of the casing portion 11 and the water discharging portion mounting hole 15a2 of the auxiliary member 15 to attach the water discharging portion 20 to the casing portion 11, the first connecting surface 21d is formed to abut against the outer cylindrical surface 11S1 around the water discharging portion mounting hole 11d in the casing portion 11. On the upper side portion of the small-diameter portion 21c, a bolt hole 21c1 is provided through which a large bolt 17 passes in the vertical direction when the water discharging portion 20 is attached to the casing portion 11. Also, as shown in FIGS. 5 and 8, on the left and right end portions on the rear side of the small-diameter portion 21c, a pair of left and right engaging convex portions 21c2 are provided so as to project toward the rear in the direction of the axis A2. The inner diameter portion 21f of the main portion 21 has a substantially cylindrical side surface shape, but the upper side portion of the small-diameter portion 21c bulges inward in the radial direction to form a tightening seat 21c3 for the large bolt 17. The bolt hole 21c1 is provided in this tightening seat 21c3. Here, the main portion 21 and the sub-portion 22 correspond to the "first component" and the "second component" in the claims, respectively. Also, the water discharging portion mounting hole 11d and the water discharging portion mounting hole 15a2 correspond to the "first mounting hole" and the "second mounting hole" in the claims, respectively. Further, the first connecting surface 21d, the large bolt 17, and the engaging convex portion 21c2 correspond to the "standing wall surface", the "bolt", and the "engaging portion" in the claims, respectively. In addition, the large-diameter portion 21a corresponds to the "general portion" in the claims.

[0026] As shown in FIGS. 2 and 5 to 7, the sub - part 22 is substantially cylindrical and has an outer diameter part 22a and an inner diameter part 22b. The outer diameter of the outer diameter part 22a is set equal to the outer diameter of the middle diameter part 21b of the main part 21, and the inner diameter of the inner diameter part 22b is set slightly larger than the outer diameter of the small diameter part 21c of the main part 21. Thus, the sub - part 22 can be axially fitted to the small diameter part 21c of the main part 21, and when fitted, the front end face part 22c faces the second connection face 21e of the main part 21 at a distance in the direction of the axis A2. An O - ring (not shown) is arranged in the groove 23 that opens in the radial direction and is formed by the second connection face 21e of the main part 21, the outer diameter face of the small diameter part 21c, and the front end face part 22c. On the upper side part of the sub - part 22, when fitted to the main part 21, a coaxial and same - diameter bolt hole 22d that extends in line with the bolt hole 21c1 of the main part 21 is provided. Also, on the upper side part of the sub - part 22, an extension part 22e that extends rearward in the direction of the axis A2 is provided, and on the upper face part of the extension part 22e, a protrusion part 22e1 that protrudes in the radial direction and engages with a part of the auxiliary member 15 to act as an anti - detachment means when the water discharge part 20 is attached to the temperature control valve part 10 is provided. Further, on the left and right end parts at the rear side of the sub - part 22, when the sub - part 22 is fitted to the main part 21, engagement concave parts 22f for preventing relative circumferential rotation by engaging with the pair of left and right engagement convex parts 21c2 of the main part 21 are arranged. When the sub - part 22 is fitted to the main part 21, the outer diameter of the outer diameter part 22a of the sub - part 22 coincides with the outer diameter of the middle diameter part 21b of the main part 21. The part where the sub - part 22 is fitted to the middle diameter part 21b and the small diameter part 21c in the water discharge part 20 corresponds to the "diameter - reduced part" in the claims. Also, the groove 23 corresponds to the "groove part" in the claims. Further, the protrusion part 22e1 and the engagement concave part 22f respectively correspond to the "locking part" and the "engaged part" in the claims.

[0027] As shown in FIGS. 2 and 5 to 7, the auxiliary member 15 has a substantially cylindrical large-diameter portion 15a having an outer diameter slightly smaller than the inner diameter of the lower inner cylinder portion 11c of the casing portion 11 by injection molding of resin, a small-diameter portion 15b provided below the large-diameter portion 15a and having an outer diameter smaller than that of the large-diameter portion 15a, and a diameter-expanded portion 15c provided between the large-diameter portion 15a and the small-diameter portion 15b. The outer diameter of the diameter-expanded portion 15c is larger than that of the large-diameter portion 15a. The large-diameter portion 15a, the small-diameter portion 15b, and the diameter-expanded portion 15c are coaxial and coincide with the axis A1 when the auxiliary member 15 is attached to the casing portion 11. When the large-diameter portion 15a is inserted into the lower inner cylinder portion 11c of the casing portion 11 from below, the diameter-expanded portion 15c is fitted into the fitting portion 11c1 and upward movement is stopped. In this state, a coaxial and same-diameter water discharge portion mounting hole 15a2 extending in the direction of the axis A2 is provided on the front side of the large-diameter portion 15a so as to coincide with the water discharge portion mounting hole 11d of the casing portion 11. Further, a notch 15a3 having a substantially U shape with an opening facing upward when viewed from the rear is provided on the rear side of the large-diameter portion 15a. On the upper surface portion 15a1 of the large-diameter portion 15a, a front protruding portion 15a4 protruding radially inward is provided on the front side, and a pair of left and right rear protruding portions 15a5 protruding radially inward are provided on the rear side. The lower surface portion 15a6 of the front protruding portion 15a4 abuts on the upper surface of the outer diameter portion 22a of the sub-portion 22 when the water discharge portion 20 is attached to the temperature control valve portion 10, and the radially inner end portion of the lower surface portion 15a6 engages with the protruding portion 22e1. In the front protruding portion 15a4, a bolt hole 15a7 extending upward is provided so as to coincide with the bolt hole 21c1 and the bolt hole 22d of the water discharge portion 20 when the water discharge portion 20 is attached to the temperature control valve portion 10 and penetrates vertically. In each of the pair of left and right rear protruding portions 15a5, a bolt hole 15a8 extending in the vertical direction penetrates. A male screw 15b1 is provided on the small-diameter portion 15b. A plurality of meat-stealing holes 15d are provided in the auxiliary member 15 to reduce the weight. Here, the radially inner end portion of the lower surface portion 15a6 corresponds to the "locked portion" in the claims. Further, the bolt hole 15a7 corresponds to the "bolt hole" in the claims.

[0028] Referring to FIGS. 2 and 5 to 7, the procedure for assembling the faucet 1 and attaching it to the top plate M will be described. In advance, the upper end portions of the water supply pipe 4a, the hot water supply pipe 4b, and the hot and cold water discharge pipe 4c are attached to the lower side of the partition portion 12 while maintaining a watertight state. Specifically, the upper end portion side of the water supply pipe 4a is attached to the lower end portion side of the first through hole 12a1 by caulking while maintaining a watertight state. Also, the upper end portion side of the hot water supply pipe 4b is attached to the lower end portion side of the second through hole 12a2 by caulking while maintaining a watertight state. Further, the upper end portion side of the hot and cold water discharge pipe 4c is attached to the lower end portion side of the third through hole 12a3 by caulking while maintaining a watertight state. In this state, the auxiliary member 15 is lifted from below so that the water supply pipe 4a, the hot water supply pipe 4b, and the hot and cold water discharge pipe 4c pass through the inner cylinder portion, and the upper surface portion 15a1 is brought into contact with the lower side of the partition portion 12. Then, the screw hole 12a4 and the bolt hole 15a7, and the pair of left and right screw holes 12a5 and the pair of left and right bolt holes 15a8 are aligned respectively, and small bolts 18 are passed through the pair of left and right screw holes 12a5 and the pair of left and right bolt holes 15a8 respectively, and the pair of rear protruding portions 15a5 are tightened and fixed to the partition portion 12. The auxiliary member 15 to which the partition portion 12 is attached is inserted into the lower inner cylinder portion 11c of the casing portion 11 from below until the enlarged diameter portion 15c fits into the fitting portion 11c1 from the side of the partition portion 12. In this state, the water discharge portion 20 is inserted into the water discharge portion mounting hole 11d and the water discharge portion mounting hole 15a2 from the side of the sub-portion 22, the bolt hole 21c1 and the bolt hole 22d are aligned with the bolt hole 15a7 and the screw hole 12a4, and the protrusion 22e1 is engaged with the radially inner end portion of the lower surface portion 15a6 of the front protruding portion 15a4. In this state, a large bolt 17 is passed through the bolt hole 21c1, the bolt hole 22d, and the bolt hole 15a7 from below and tightened against the screw hole 12a4 of the partition portion 12. At this time, the water discharge portion 20 is previously fitted with the sub-portion 22 to the main portion 21, and an O-ring is arranged in the formed groove 23. Next, the cartridge 13 is inserted into the upper inner cylinder portion 11b of the casing portion 11, and the mounting portion 16b of the cover member 16 is inserted and fixed to the partition portion 12. Specifically, it is fixed by screwing the female screw 16b1 provided on the lower end portion side of the mounting portion 16b to the male screw 12b provided on the upper end portion side of the partition portion 12. Then, the lower end portion of the base portion 14a is fitted to the operation portion 13b of the cartridge 13, and the operation handle 14 is attached.One end of a flexible pipe 4c1 is connected to the lower end of the hot water discharge pipe 4c while maintaining a watertight state, and the other end is arranged to pass through the inner cylinder of the auxiliary member 15 and the inner cylinder of the water discharge part 20, and a connection member 4c2 is attached to the tip. The connection member 4c2 is connected to the inner cylinder of the extraction discharge pipe 3 while maintaining a watertight state, and is detachably supported by the inner diameter part 21f on the front end side of the water discharge part 20. Thus, the assembly of the faucet 1 is completed. The assembled faucet 1 has its small diameter part 15b inserted downward through a hole (not shown) in the top plate M having an inner diameter larger than the outer diameter of the small diameter part 15b provided on the top plate M and smaller than the outer diameter of the enlarged diameter part 15c, and the lower end part of the enlarged diameter part 15c is arranged to contact the upper surface of the top plate M. In this state, a nut (not shown) is tightened against the male thread 15b1 of the small diameter part 15b, and the lower end part of the enlarged diameter part 15c and the nut sandwich the top plate M to fix it to the top plate M. After that, the lower end of the water supply pipe 4a is connected to the water supply pipe, and the lower end of the hot water supply pipe 4b is connected to the hot water supply pipe.

[0029] The present embodiment configured as described above has the following effects. Since the casing part 11 of the temperature control valve part 10 and the water discharge part 20 of the faucet body 2 are each formed in a substantially cylindrical shape, they can be manufactured by injection molding or, for example, cutting without using complicated processes such as casting. Also, the attachment of the water discharge part 20 to the temperature control valve part 10 is performed by inserting one end side of the water discharge part 20 into the water discharge part attachment hole 11d and the water discharge part attachment hole 15a2 and arranging them so that the axial directions intersect with respect to the casing part 11, and then fastening the upper side part of the small diameter part 21c and the upper side part of the auxiliary part 22 to the partition wall part 12 with the large bolt 17. Therefore, a faucet 1 with a low manufacturing cost structure can be provided. Further, since the groove for arranging the O-ring, which is complicated to process when the water discharge part 20 is formed of a single part, is formed as a groove 23 that opens in the radial direction formed by the second connection surface 21e, the outer diameter surface of the small diameter part 21c, and the front end surface part 22c when the auxiliary part 22 is combined with the main part 21, the manufacturing of the water discharge part 20 is easy.

[0030] Further, with respect to the casing portion 11, the small-diameter portion 21c to which the middle-diameter portion 21b and the auxiliary portion 22 of the water discharge portion 20 are attached is inserted into the water discharge portion mounting hole 11d and the water discharge portion mounting hole 15a2, and the first connection surface 21d is mounted in a state of abutting against the outer cylindrical surface 11S1 around the water discharge portion mounting hole 11d in the casing portion 11. As a result, the water discharge portion 20 is less likely to swing in a direction perpendicular to the axis A2 direction with respect to the casing portion 11 and is more firmly connected.

[0031] Furthermore, with the partition wall portion 12 fastened and supported by the pair of left and right rear protruding portions 15a5 of the auxiliary member 15 with small bolts 18 respectively, the water discharge portion 20 with one end side inserted into the water discharge portion mounting hole 11d and the water discharge portion mounting hole 15a2 is fastened and fixed to the partition wall portion 12 via the front protruding portion 15a4 of the auxiliary member 15 by a large bolt 17. As a result, the water discharge portion 20 is firmly attached to the temperature control valve portion 10.

[0032] Furthermore, the water discharge portion 20 is attached to the temperature control valve portion 10 in a state where the protruding portion 22e1 is engaged with the radially inner end portion of the lower surface portion 15a6 of the front protruding portion 15a4 of the temperature control valve portion 10. As a result, the water discharge portion 20 is suppressed from moving in the axis A2 direction away from the temperature control valve portion 10, and play when a force in the axis A2 direction is applied to the water discharge portion 20 can be suppressed.

[0033] In addition, the main portion 21 and the auxiliary portion 22 are combined in a state where the pair of left and right engaging convex portions 21c2 of the main portion 21 are engaged with the pair of left and right engaging concave portions 22f of the auxiliary portion 22, so relative rotation about the axis A2 is suppressed, and play when a force is applied to the water discharge portion 20 in a direction perpendicular to the axis A2 direction can be suppressed.

[0034] As described above, specific embodiments have been described, but the present invention is not limited to their appearance and configuration, and various changes, additions, and deletions are possible without changing the gist of the present invention. For example, the following are examples.

[0035] 1. In the above embodiment, the partition wall portion 12 is configured to be supported by the auxiliary member 15 inserted into the lower inner cylinder portion 11c of the casing portion 11. However, it is not limited to this, and it can also be configured to be attached to the lower inner cylinder portion 11c of the casing portion 11 by screwing.

[0036] 2. In the above embodiment, a pair of left and right engaging convex portions 21c2 are provided on the main portion 21, and a pair of left and right engaging concave portions 22f are provided on the sub-portion 22. However, it is not limited to this, and a set of one engaging convex portion 21c2 and one engaging concave portion 22f may be sufficient. Further, an engaging concave portion may be provided on the main portion 21 and an engaging convex portion may be provided on the sub-portion 22. However, in that case, the protruding direction of the engaging convex portion is opposite to that of the above embodiment, and accordingly, the recessed direction of the engaging concave portion also needs to be changed.
