However, when a tubular member such as a pipe is used as the main body, it is difficult to provide the water intrusion prevention structure integrally with the main body.

One aspect of the embodiment is made in view of the above, and provides a faucet device capable of preventing water from entering below an installation surface while using a tubular main body. With the goal.

A faucet device according to an aspect of the embodiment, a tubular body portion, a water discharge portion that discharges water, an operation rod that is inserted into the body portion and that operates a drain plug, and a peripheral surface of the body portion. An opening provided to allow the operating portion of the operating rod to project to the outside of the main body portion, and a base portion inserted into the main body portion and having an outer peripheral surface along the inner peripheral surface of the main body portion below the opening portion. The water intrusion prevention member has and a peripheral surface sealing member provided on the outer peripheral surface of the base portion.

This makes it possible to easily form the water intrusion prevention structure inside the main body while using the tubular main body, and prevent water from dripping below the installation surface.

In addition, the water entry prevention member is a through hole that penetrates the rod portion of the operation rod in the axial direction of the main body portion, and a wall that faces the opening portion with the through hole interposed therebetween and that rises upward from the base portion. And the upper end of the wall is higher than the upper end of the opening.

If water enters through the opening and enters the area surrounded by the wall, the water may travel down the water supply hose or the hot water supply hose and may drip below the installation surface. In the faucet device according to one aspect of the embodiment, since the upper end of the wall portion is configured to be higher than the upper end of the opening portion, even if water enters from the opening portion, it falls within the region surrounded by the wall portion. It is possible to prevent water from entering and to prevent the water from dripping below the installation surface.

Further, an end face seal member is provided on the lower end face of the water intrusion prevention member so as to surround the through hole. Accordingly, it is possible to prevent the water that has entered from the opening from leaking between the water entry prevention member and the member provided below the water entry prevention member through the through hole.

Further, the end face seal member has a larger amount of elastic deformation than the peripheral face seal member. The elastic deformation amount refers to the amount of deformation of the elastic body when a constant force is applied. That is, when a constant force is applied to the end face seal member and the peripheral face seal member, the end face seal member is elastically deformed more than the peripheral face seal member. Therefore, compared with the case where the material used for the peripheral surface seal member seals between the water intrusion prevention member and the fixed rod receiving portion, the water intrusion prevention member and the fixed rod receiving portion are fixed to the water intrusion prevention member due to the tolerance. Even if a gap is formed between the rod receiving portion and the rod receiving portion, the water intrusion prevention member and the fixed rod receiving portion can be appropriately sealed regardless of the size of the gap.

The water intrusion prevention member has a convex portion on the outer peripheral surface of the base portion, and the main body portion has a concave portion on the inner peripheral surface corresponding to the convex portion. For this reason, when the water intrusion prevention member is inserted into the main body, the convex portion of the water intrusion prevention member fits into the concave portion of the main body to prevent the water intrusion prevention member 22 from rotating with respect to the main body 2. You can

According to one aspect of the embodiment, it is possible to provide a faucet device that can prevent water from entering below an installation surface while using a tubular main body.

The operating rod 10 includes a rod portion 110 extending in the vertical direction and an operating portion 112 extending in the horizontal direction from an upper portion of the rod portion 110. The operating portion 112 is provided on the peripheral surface of the main body portion 2 from the main body portion 2. A vertically extending opening 202 (see FIGS. 2 and 3) is provided to be projected. The user can move the operation rod 10 in the vertical direction by operating the operation unit 112.

Next, the internal configuration of the water faucet device 1 according to the embodiment will be described with reference to FIG. FIG. 2 is a cross-sectional view of the water faucet device 1 according to the embodiment.

The faucet device 1 includes a valve mechanism 14 that adjusts the temperature and flow rate of wash water, a water passage member 16, a valve seat 18, a valve seat support member 20 that supports the valve seat 18 from below, and a water intrusion prevention member. And 22.

The valve mechanism 14 is inserted into the inside of the main body 2 from the opening on the upper end side of the main body 2, and is connected to the valve seat 18 via the water passage member 16. The valve mechanism 14 is a so-called single-lever cartridge, and includes a casing member 140 having openings above and below, a fixed valve body 142, and a fixed valve body 142 fixed to the lower end of the casing member 140 from below. A fixed valve body holding member 144 to be fixed, a movable valve body 146 slidably and rotatably arranged on the upper side of the fixed valve body 142, and a valve body operating shaft 148 for operating the movement of the movable valve body 146. Prepare The casing 140 accommodates the fixed valve body 142 and the movable valve body 146, and is arranged so that the valve body operating shaft 148 projects from the upper opening of the casing 140.

The fixed valve body 142 includes a water inlet, a hot water inlet, and a hot and cold water mixture outlet, which are not shown. The water inlet communicates with a first water passage (not shown) provided in the water passage member 16. The hot water inlet communicates with a first hot water passage (not shown) provided in the water passage member 16. The hot and cold water mixture outlet communicates with the water discharger 4. The movable valve body 146 is a member slidably arranged on the fixed valve body 142, and a valve body recess 147 is provided on the upper surface of the movable valve body 146.

The valve body operating shaft 148 is a rod-shaped member, the lower end is rotatably fitted in the valve body recess 147, and the upper end is connected to the lever 6. Therefore, the valve body operating shaft 148 is rotated in the vertical direction and the left-right direction by operating the lever 6.

In the water-stopped state, the movable valve body 146 is arranged so as to close the water inlet and the hot water inlet of the fixed valve body 142. When the lever 6 is rotated about the horizontal axis, the movable valve body 146 translates on the fixed valve body 142, and the water inlet and the hot water inlet of the fixed valve body 142 are opened. As a result, the water and the hot water supplied from the water supply hose 32 and the hot water supply hose 34 respectively flow into the valve mechanism 14 through the water inlet and the hot water inlet, and the mixed hot and cold water is mixed in the fixed valve body 142. It flows out from the hot and cold water mixture outlet. The hot and cold water mixture flowing out from the hot and cold water mixture outlet passes through the water discharge pipe 42 and is discharged from the water discharge port 40.

Further, when the lever 6 is rotated about the horizontal axis and the movable valve body 146 moves in translation, the opening degrees of the water inlet and the hot water inlet of the fixed valve body 142 change, and the moving amount of the movable valve body 146 changes. Accordingly, the flow rate of the hot and cold water mixture flowing out from the valve mechanism 14 changes. Further, when the lever 6 is rotated about the vertical axis, the movable valve body 146 rotates on the fixed valve body 142, and the ratio of the opening degrees of the water inlet and the hot water inlet of the fixed valve body 142 changes. Then, the temperature of the hot and cold water mixture flowing out from the valve mechanism 14 changes.

The water passage member 16 supplies the water flowing in from the valve seat 18 to the water inlet of the valve mechanism 14, and the first water passage supplying the hot water flowing from the valve seat 18 to the water inlet of the valve mechanism 14. 1 hot water passage.

The valve seat 18 is a cylindrical member having a second water passage 186 and a second hot water passage 188 described later (see FIG. 5 ). The second water passage 186 is connected to the water supply hose 32 (see FIG. 1) that supplies water from the water supply source, and communicates with the first water passage of the water passage member 16. The second hot water passage 188 is connected to a hot water supply hose 34 (see FIG. 1) that supplies hot water from a hot water supply source, and communicates with the first hot water passage of the water passage member 16.

The valve seat support member 20 can support the valve seat 18 from below. Therefore, even if the tubular main body 2 is used, the valve mechanism 14 and the valve seat 18 can be supported inside the main body 2. Further, the valve seat support member 20 is provided with an outer edge along the inner peripheral surface of the main body 2. The outer edge of the valve seat support member 20 is welded to the inner peripheral surface of the main body 2. As a result, the valve seat support member 20 is supported by the main body 2. Therefore, as compared with the case where the outer edge of the valve seat support member 20 is not welded to the inner peripheral surface of the main body portion 2, the valve seat support member 20 according to the embodiment more reliably secures the valve mechanism 14 and the valve seat 18. Can be supported by.

The water intrusion prevention member 22 is provided on the base 220 along the inner peripheral surface of the main body 2, the wall 222 rising upward from the base 220, and the base 220, and penetrates the operation rod 10 in the axial direction of the main body 2. A through hole 224, a peripheral surface sealing member 226, and an end surface sealing member 228 are provided.

An outer peripheral surface along the inner peripheral surface of the main body 2 is formed on the base 220 arranged inside the main body 2, and the outer peripheral surface is located below the opening 202. A peripheral surface seal member 226 is provided on the outer peripheral surface of the base 220. Therefore, even if water enters from the opening 202, it is possible to prevent the water from dripping downward from between the outer peripheral surface of the base 220 and the inner peripheral surface of the main body 2.

The wall 222 rises upward from the base 220 and faces the opening 202. The wall 222 is arranged at a position sandwiching the through hole 224, in other words, at a position farther from the opening 202 than the through hole 224. The water supply hose 32 and the hot water supply hose 34 pass through an area 227 surrounded by the wall 222.

If water enters through the opening 202 and enters the area 227 surrounded by the wall 222, the water may travel down the water supply hose 32 or the hot water supply hose 34 and may drip down to the lower part of the counter 12. .. The upper end of the wall portion 222 according to the embodiment is configured to be higher than the upper end of the opening portion 202 by a height A. Therefore, even if water enters from the opening 202, it is possible to prevent the water from entering the region 227 surrounded by the wall 222 and prevent the counter 12 from dripping down.

The end face seal member 228 is provided on the lower end face of the water intrusion prevention member 22 so as to surround the through hole 224. If water enters through the opening 202, the water may pass through the through hole 224, leak out between the water intrusion prevention member 22 and a fixed rod receiving portion 24, which will be described later, and may drip below the counter 12. There is.

In the water faucet device 1 according to the embodiment, even if water enters from the opening 202, the end face seal member 228 seals between the water intrusion prevention member 22 and the fixed rod receiving portion 24, so that the water is water. It is possible to prevent leakage from between the intrusion prevention member 22 and the fixed rod receiving portion 24.

Further, the end face seal member 228 is formed of a member having a larger elastic deformation amount than the peripheral face seal member 226. Here, the amount of elastic deformation refers to the amount of deformation of the elastic body when a constant force is applied. That is, when a constant force is applied to the end face seal member 228 and the peripheral face seal member 226, the end face seal member 228 is elastically deformed more than the peripheral face seal member 226. Therefore, compared with the case where the material used for the peripheral surface seal member 226 is used to seal between the water intrusion prevention member 22 and the fixed rod receiving portion 24, the water intrusion prevention member 22 and the fixed rod receiving portion 24 have a tolerance difference. Even if a gap is formed between the intrusion prevention member 22 and the fixed rod receiving portion 24, the water intrusion prevention member 22 and the fixed rod receiving portion 24 can be appropriately sealed regardless of the size of the gap. it can.

The faucet device 1 further includes a fixed rod receiving portion 24, a fixed rod 26, a movable portion 28, and a seat packing 30.

The fixed rod receiving portion 24 is inserted into the inside of the main body portion 2 through an opening on the side facing the counter 12 in which the faucet device 1 is installed, that is, an opening on the lower end side of the main body portion 2, and the main body portion 8 is inserted by the base portion 8. It is a cylindrical member that is confined inside 2.

The fixing rod 26 is, for example, a headless bolt and has a thread groove on its peripheral surface. The fixed rod 26 passes through the pedestal portion 8, the upper end is fixed to the fixed rod receiving portion 24 above the counter 12, and the lower end projects from the end surface of the main body 2. A movable portion 28 is attached to the fixed rod 26 below the counter 12. In other words, the movable portion 28 is arranged at a position sandwiching the pedestal portion 8 with the fixed rod receiving portion 24. The thickness of the fixed rod 26 in the vertical direction is substantially constant, and the movable portion 28 can change the distance along the fixed rod 26 to the fixed rod receiving portion 24.

The movable portion 28 includes a nut 280 and a contact member 282. When the nut 280 is rotated through the fixed rod 26, the nut 280 moves vertically along the fixed rod 26. The contact member 282 is a horseshoe-shaped member that surrounds the fixed rod 26, the water supply hose 32, and the hot water supply hose 34. The movable portion 28 is not limited to the nut 280 and the contact member 282 according to the embodiment, and may be any member that can change the distance between the fixed rod receiving portion 24 and the fixed rod 26.

When the nut 280 is moved upward with respect to the fixed rod 26, the contact member 282 is sandwiched between the nut 280 and the counter 12. When the nut 280 is further rotated, the contact member 282 is pressed against the lower surface of the counter 12, and accordingly, the fixed rod 26 and the fixed rod receiving portion 24 fixed to the fixed rod 26 are pulled downward. Then, the fixed rod receiving portion 24 contacts the pedestal portion 8, and the pedestal portion 8 is pressed against the upper surface of the counter 12. As a result, the main body 2 fastened to the pedestal 8 is easily fixed to the counter 12.

Further, the contact member 282 has a larger end surface area than the nut 280, and a larger contact area with the counter 12. Therefore, as compared with the case where the nut 280 is pressed against the lower surface of the counter 12, it is possible to more stably fix the main body 2 to the counter 12 when the contact member 282 is pressed against the lower surface of the counter 12. it can.

The seat packing 30 is arranged between the pedestal portion 8 and the counter 12. The seat packing 30 is an annular member made of an elastic material and is arranged so as to surround the mounting hole 120 provided in the counter 12. By arranging the seat packing 30, even if water flows over the counter 12, the water will flow through the gap between the lower end surface of the pedestal portion 8 and the counter 12 and hang down from the mounting hole 120 to the lower side of the counter 12. Can be prevented.

Next, the internal configuration of the main body 2 according to the embodiment will be described more specifically with reference to FIG. FIG. 3 is a cross-sectional view of the main body portion 2 according to the embodiment.

As shown in FIG. 3, the main body 2 is a cylindrical member having openings at the upper end and the lower end, and an opening 202 for allowing the operating portion 112 to project from the outer peripheral surface of the main body 2, and a valve on the inner peripheral surface. A first step portion 200 that supports the valve seat support member 20 by coming into contact with the lower end surface of the seat support member 20, a second step portion 212, a recess 210 provided in the second step portion 212, and a water discharge portion 4. A water passage 214 communicating therewith is provided. A process for fastening the pedestal 8, for example, a thread cutting process for screwing the pedestal 8 is applied to the lower end of the main body 2.

The upper portion of the first step portion 200 has an inner diameter larger than the outer diameter of the valve seat support member 20, and the lower portion of the first step portion 200 has an inner diameter smaller than the outer diameter of the valve seat support member 20. Therefore, the valve seat support member 20 is inserted from the opening on the upper end side of the main body 2 and supported by the first step portion 200. When the valve seat support member 20 is welded to the inner peripheral surface of the main body portion 2, the valve seat support member 20 can be welded while being supported by the first step portion 200, so that the valve seat support member 20 is placed at a predetermined position. Easy to weld.

A second step portion 212 is provided on the lower end side of the first step portion 200, and a recess 210 is provided in the second step portion 212. The upper portion of the second step portion 212 has an inner diameter smaller than the outer diameter of the fixed rod receiving portion 24, and the lower portion of the second step portion 212 has an inner diameter larger than the outer diameter of the fixed rod receiving portion 24. Therefore, the fixed rod receiving portion 24 is inserted from the opening on the lower end side of the main body portion 2 and is restricted from moving above the second step portion 212. The water passage 214 is provided on the upper end side of the first step portion 200. The hot and cold water mixture supplied from the hot and cold water mixture outlet of the fixed valve body 142 passes through the water passage port 214 and flows out to the water discharge part 4.

Next, the valve seat support member 20 according to the embodiment will be described with reference to FIGS. FIG. 4 is a perspective view of the valve seat support member 20 according to the embodiment. FIG. 5 is a perspective view of the valve seat support member 20 supporting the valve seat 18 as seen from the bottom side. FIG. 6 is a bottom view of the valve seat support member 20.

As shown in FIG. 4, the valve seat support member 20 is an annular member and includes a valve seat support member opening 204 that is asymmetric with respect to the central axis of the valve seat support member 20. The valve seat support member opening 204 has a first region 206 and a second region 208. The first region 206 is a region where the shaft portion 183 of the screw 180 provided on the valve seat 18 is inserted, and the second region 208 is a region where the water supply hose 32 and the hot water supply hose 34 are inserted. The shape of the valve seat support member opening 204 is shorter than the portion from the center of the valve seat support member 20 to the outer end of the shaft portion 183 and shorter than the portion from the center of the valve seat support member 20 to the outer end of the shaft portion 183. It suffices to have a portion and may have, for example, an elliptical shape.

Since the water supply hose 32 and the hot water supply hose 34 are connected to the valve seat 18, if the valve seat 18 rotates with respect to the valve seat support member 20, the water supply hose 32 and the hot water supply hose 34 are twisted in the main body 2. There is a risk that In the water faucet device 1 according to the embodiment, as shown in FIG. 5, the valve seat 18 includes a screw 180 that faces the valve seat support member opening 204. Then, when the valve seat 18 is supported by the valve seat support member 20, the screw 180 provided on the valve seat 18 is inserted into the first region 206 of the valve seat support member opening 204. Therefore, even if the force for rotating the valve seat 18 acts on the valve seat 18, the shaft portion 183 of the screw 180 extends from the center of the valve seat support member 20 provided in the first region 206 to the outer end of the shaft portion 183. Since it also abuts the short portion, rotation of the valve seat 18 with respect to the valve seat support member 20 can be suppressed. Therefore, it is possible to prevent the water supply hose 32 and the hot water supply hose 34 from twisting in the main body 2. Further, by using the screw 180, a convex portion can be easily provided on the valve seat 18.

Further, as shown in FIG. 6, the screw 180 includes a head portion 182 that projects below the first region 206. The head portion 182 overlaps at least a part of the end surface of the valve seat supporting member 20 when viewed in the direction along the central axis of the valve seat supporting member 20. Therefore, when the valve seat 18 moves upward, the head 182 comes into contact with the lower end surface of the valve seat support member 20, so that the upward movement of the valve seat 18 is restricted.

As described above, in the water faucet device 1 according to the embodiment, the movable valve body 146 and the fixed valve body 142 slide in order to control the flow rate and temperature of the wash water. 14 will wear out. Since the worn valve mechanism 14 needs to be replaced, the valve mechanism 14 is taken out from the opening on the upper end side of the main body 2. However, when the valve mechanism 14 is taken out from the opening on the upper end side of the main body portion 2, the reaction force of the water supply hose 32 and the hot water supply hose 34 may cause the valve seat 18 to move above the valve seat support member 20. In the water faucet device 1 according to the embodiment, it is possible to prevent the screw 180 attached to the valve seat 18 from contacting the lower end surface of the valve seat support member 20 and moving the valve seat 18 upward. It is easy to replace the valve mechanism 14.

Next, the water intrusion prevention member 22 according to the embodiment will be described with reference to FIGS. 7 and 8. FIG. 7 is a perspective view of the water intrusion prevention member 22. FIG. 8 is a bottom view of the water intrusion prevention member 22.

As shown in FIG. 7, the water intrusion prevention member 22 includes a protrusion 229 on the outer peripheral surface of the base 220 in addition to the above-described configuration. The convex portion 229 is formed in a position and size corresponding to the concave portion 210 (see FIG. 3) provided on the inner peripheral surface of the main body 2. When the water intrusion prevention member 22 is inserted into the main body portion 2, the convex portion 229 fits into the concave portion 210, so that rotation of the water intrusion prevention member 22 with respect to the main body portion 2 is restricted.

Then, the water intrusion prevention member 22 rotates with respect to the main body portion 2 and interferes with the rod portion 110 inserted into the water intrusion prevention member 22, thereby hindering the vertical movement of the operation rod 10. Can be prevented.

Further, as shown in FIG. 8, a plurality of protrusions 229 (here, three) are provided on the outer peripheral surface of the base 220 of the water intrusion prevention member 22, but the three protrusions 229 are the outer periphery of the base 220. It is arranged at unequal intervals with respect to the surface, not at equal intervals. Similarly, the three concave portions 210 corresponding to the three convex portions 229 are also arranged not at equal intervals but at unequal intervals with respect to the inner peripheral surface of the main body 2. Therefore, by inserting the water intrusion prevention member 22 into the main body portion 2 so that the convex portion 229 fits into the concave portion 210, the direction of the water intrusion prevention member 22 with respect to the main body portion 2 is correctly determined, and the water intrusion portion is inserted in the wrong direction. It is possible to prevent the prevention member 22 from being inserted into the main body 2.

Next, the fixed rod receiving portion 24 according to the embodiment will be described with reference to FIGS. 9 and 10. FIG. 9 is a perspective view of the fixed rod receiving portion 24 as seen from the upper surface side. FIG. 10 is a plan view of the fixed rod receiving portion 24.

As shown in FIG. 9, the fixed rod receiving portion 24 includes a fixed rod receiving portion screw 240, a water supply hose through hole 244 into which the water supply hose 32 is inserted, a hot water supply hose through hole 246 into which the hot water supply hose 34 is inserted, An operation rod through hole 248 into which the operation rod 10 is inserted and a fixed rod holding hole 249 are provided.

Further, as shown in FIG. 10, the fixed rod receiving portion 24 includes a plurality of fixed rod receiving portion screws 240 (here, two), and each fixed rod receiving portion screw 240 has a fixed rod receiving portion screw head 242. Prepare The fixed rod receiving portion screw head 242 is provided on the end surface of the fixed rod receiving portion 24 along the outer periphery of the fixed rod receiving portion 24. Further, the fixing rod receiving portion screw head 242 is formed in a position and size corresponding to the recess 210 (see FIG. 3) provided in the inner peripheral surface of the main body 2.

If the fixed rod receiving part screw head is provided on the peripheral surface of the fixed rod receiving part, the fixed rod receiving part screw head protrudes outside the outer periphery of the fixed rod receiving part. It is necessary to increase the size of the main body portion having the concave portion corresponding to 1 in the outer peripheral direction. On the other hand, since the fixed rod receiving portion screw head 242 according to the embodiment is provided on the end surface of the fixed rod receiving portion 24 along the outer periphery of the fixed rod receiving portion 24, the main body portion 2 is enlarged in the outer peripheral direction. It is possible to provide the concave portion 210 corresponding to the fixed rod receiving portion screw head 242 without the need.

Further, by inserting the fixing rod receiving portion 24 into the main body portion 2 so that the fixing rod receiving portion screw heads 242 are fitted in the recesses 210 formed at unequal intervals, the orientation of the fixing rod receiving portion 24 with respect to the main body portion 2 is improved. Therefore, it is possible to prevent the fixed rod receiving portion 24 from being inserted into the main body portion 2 in the wrong direction.

Further, in the state where the fixed rod receiving portion screw head 242 is fitted in the recess 210, even if a force for rotating the fixed rod receiving portion 24 acts on the fixed rod receiving portion 24, the fixed rod receiving portion screw head 242 is not depressed. Since it abuts in the circumferential direction, the rotation of the fixed rod receiving portion 24 with respect to the main body portion 2 is restricted. Therefore, the fixed rod receiving portion 24 rotates with respect to the main body portion 2, the water supply hose 32 and the hot water supply hose 34 are twisted, and the water supply hose 32 and the hot water supply hose 34 are inserted into the water supply hose through hole 244 and the hot water supply hose through hole 246. It is possible to prevent them from coming into contact with each other and breaking down.

The faucet device 1 according to the embodiment has a simple structure in which the fixed rod receiving portion 24 is provided with the fixed rod receiving portion screw 240 and the main body portion 2 is provided with the concave portion 210. Since erroneous assembly and rotation can be prevented, the manufacturing cost can be suppressed.

Further, since the concave portion 210 is formed in a position and size corresponding to both the convex portion 229 provided with the water intrusion prevention member 22 and the fixed rod receiving portion screw head 242, the convex portion 229 and the fixed rod receiving portion screw head are formed. Compared with the case where separate recesses corresponding to the respective 242 are provided, the labor required for manufacturing can be reduced.

Next, the valve seat 18 according to the modification will be described. FIG. 11 is a perspective view of the valve seat support member 20 in a state of supporting the valve seat 18 according to the modification, as viewed from the bottom surface side.

A fixed rod receiving portion 24 inserted into the portion 2, a fixed rod 26 having one end fixed to the fixed rod receiving portion 24 and the other end protruding from an opening on the side facing the surface on which the faucet device 1 is installed; Along with the fixing rod 26, the fixing rod 26 is passed between the fixing rod receiving portion 24 and the pedestal portion 8 for confining the fixing rod receiving portion 24 and the fixing rod receiving portion 24. And a movable portion 28 whose distance from the fixed rod receiving portion 24 can be changed.

Therefore, the main body 2 can be easily fixed to the counter 12 as compared with the conventionally proposed faucet device.

Further, the faucet device 1 according to the embodiment includes a tubular main body portion 2, a water discharge portion 4 that discharges water, an operation rod 10 that is inserted into the main body portion 2 and that operates a drain plug, and a main body portion 2. An opening 202 provided on the peripheral surface for allowing the operating portion 112 of the operating rod 10 to project to the outside of the main body portion, and an outer peripheral surface on the inner peripheral surface of the main body portion 2 inserted below the opening portion 202 and below the opening portion 202. A water intrusion prevention member 22 having a base portion 220 along which the peripheral surface sealing member 226 is provided on the outer peripheral surface of the base portion 220.

Therefore, it is possible to prevent water from entering below the counter 12 while using the cylindrical main body 2.

Further, the faucet device 1 according to the embodiment includes a tubular main body portion 2, a water discharge portion 4 that discharges water, a valve seat support member 20 that is inserted into the main body portion 2 and is supported by the main body portion 2, and a main body. A valve seat 18 inserted into the portion 2 and supported by the valve seat support member 20 and a valve mechanism 14 inserted into the body portion 2 and connected to the valve seat 18 are provided.

Therefore, the valve mechanism 14 and the valve seat 18 can be supported inside the main body 2 while using the tubular main body 2.
