Description

Aspects of the present invention generally relate to a water supply unit.

As a mounting structure for the wall member in the water supply unit, a structure in which the wall member is inserted and arranged in a wall mounting recess provided on the outer edge of the floor member is known. In such a configuration, a caulking material is applied to the boundary between the floor member and the wall member in order to prevent the water in the water supply unit from leaking to the outside of the water supply unit (patented). Document 1).

However, since the application work of the caulking material is performed after assembling the wall member to the floor member, the accuracy is left to the construction technique of the on-site builder. That is, if the construction technique of the on-site builder is not sufficient, there is a risk that the caulking material may be forgotten to be applied or the caulking material may not be applied correctly, and watertightness may not be ensured. Therefore, there is a problem that the watertightness in the water supply unit cannot be guaranteed on the manufacturer side of the floor member or the wall member.

Here, a configuration in which a seal member is provided between the bottom surface of the wall member and the inner bottom surface of the wall mounting recess is also conceivable. However, the amount of gap between the wall member and the floor member varies due to the influence of the product error of each member, the inclined state of the floor member, and the like. In this case, in a place where the amount of gap between the bottom surface of the wall member and the inner bottom surface of the wall mounting recess is large, sufficient pressure may not be applied to the sealing member, and the sealing property may be insufficient. Further, in order to ensure the sealing property, it is conceivable to form a large height of the sealing member in consideration of a large gap amount. However, since the wall member is inserted into the wall mounting recess from the inside of the water supply unit, the seal member may fall from the inside to the outside of the water supply unit, and the arrangement of the wall member may become unstable.

Japanese Unexamined Patent Publication No. 2019-52509

The present invention has been made based on the recognition of such a problem, and an object of the present invention is to provide a water supply unit capable of suppressing water from leaking from the inside of the unit to the outside of the unit.

The first invention is a floor member having a floor portion and a wall-mounting recess provided along the outer edge of the floor portion, a wall member inserted into the wall-mounting recess, the wall-mounting recess, and the wall-mounting recess. A seal member that watertightly closes the space between the wall member and the wall member is provided, and the wall-mounted recess has an inner bottom surface that is recessed below the upper surface of the floor portion and an inner surface surface that extends upward from the inner bottom surface. The seal member has a deformable material having one side provided on the inner side surface, the other side extending toward the inside of the wall-mounted recess, and being pressed by the wall member to be deformable, and the deformable material. It is a water supply unit characterized by having an adhesive material provided on the upper surface of the above surface and having adhesiveness.

According to this water supply unit, when the wall member is installed on the floor member, the wall member is inserted in a state of being inclined with respect to the wall mounting recess due to the inclined state of the floor member and the manufacturing tolerance of the wall member. However, it is possible to absorb the fluctuation amount of the gap due to the inclination of the wall member due to the deformation of the deformable material. As a result, the wall member can be accurately attached to the wall mounting recess.

Further, the adhesive material provided on the upper surface of the deformable material can effectively seal between the wall member and the wall-mounted recess. In this case, even in a place where the amount of gap between the wall member and the wall-mounted recess is large, the amount of deformation of the deformable material changes, so that the sealing property can be firmly maintained. In addition, the sealing member extends from the inner surface of the wall mounting recess. Therefore, even in various wall-mounted recesses having different depth dimensions, the same sealing member can be used only by adjusting the mounting height of the sealing member. Therefore, since the thickness dimension of the seal member can be reduced, the stability is excellent, and watertightness can be ensured even if the gap amount between the wall member and the wall mounting recess changes.

The second invention is a floor member having a floor portion and a wall-mounting recess provided along the outer edge of the floor portion, a wall-supporting member provided in the wall-mounting recess, and the wall-supporting member. A wall member inserted into the wall-mounting recess via the wall member and a seal member that watertightly closes between the wall receiving member and the wall member, and the wall-mounting recess is formed from the upper surface of the floor portion. Also has an inner bottom surface recessed downward and an inner side surface extending upward from the inner bottom surface, and the wall receiving member has a bottom surface portion in contact with the inner bottom surface portion of the wall mounting recess and the bottom surface portion. The seal member has a side surface portion extending upward from the wall and facing the inner side surface of the wall-mounting recess, and the seal member is provided on one side of the side surface portion and extends toward the inside of the wall receiving member on the other side. The water supply unit is characterized by having a deformable material that can be deformed by being pressed by the wall member, and an adhesive material that is provided on the upper surface of the deformable material and has adhesiveness.

According to this water supply unit, when the wall member is installed on the floor member, the wall member is inserted in a tilted state with respect to the wall receiving member due to the tilted state of the floor member, the manufacturing tolerance of the wall member, and the like. However, it is possible to absorb the fluctuation amount of the gap due to the inclination of the wall member due to the deformation of the deformable material. As a result, the wall member can be attached to the wall receiving member with high accuracy.

Further, the adhesive material provided on the upper surface of the deformable material can effectively seal between the wall member and the wall receiving member. In this case, since the amount of deformation of the deformable material changes even in a place where the amount of gap between the wall member and the wall receiving member is large, the sealing property can be firmly maintained. In addition, the seal member extends from the side surface portion of the wall receiving member. Therefore, even in various wall-mounted recesses having different depth dimensions, the same sealing member can be used only by adjusting the mounting position of the side surface portion. Therefore, since the thickness dimension of the seal member can be reduced, the stability is excellent, and watertightness can be ensured even if the gap amount between the wall member and the wall receiving member changes.

According to a third aspect of the invention, in the first or second invention, the deformable material can be elastically deformed in the vertical direction by having one side having a fixed end and the other side having a free end, and the deformable material can be elastically deformed vertically. The water peripheral unit is characterized in that the thickness dimension in the direction is smaller than the thickness dimension in the vertical direction of the adhesive material.

According to this water supply unit, the crimping force between the wall member and the adhesive material can be adjusted by elastic deformation of the deformable material. As a result, the adhesive strength of the adhesive material can satisfy the balance between the water stoppage and the removal of the wall member. Therefore, since the adhesive material of the seal member is excellent in peelability from the wall member, the workability of the wall member attachment / detachment work can be improved.

A fourth invention is a water supply unit according to any one of the first to third aspects, wherein the upper surface of the deformable material is formed in an uneven shape.

According to this water supply unit, the contact surface (adhesive surface) between the deformable material and the adhesive material can be enlarged. Therefore, it is possible to prevent the adhesive material from peeling off from the deformed material when the wall member is removed. Further, when the adhesive material is pressed against the wall member, it is possible to prevent the adhesive material from sliding in the horizontal direction with respect to the deformed material. As a result, it is possible to prevent the adhesive material from peeling off from the deformed material.

A fifth aspect of the invention is characterized in that, in any one of the first to fourth inventions, the deformable material has an upwardly inclined portion in which the other side is inclined upward toward the opening side of the wall-mounted recess. It is a water supply unit.

According to this water supply unit, even if the adhesive force of the adhesive material is weakened in order to improve the peelability between the wall member and the adhesive material when the wall member is removed, the deformable material is inclined upward when the wall member is attached. Since the urging force of the portion is increased, it is possible to prevent the adhesive material from peeling from the deformed material. Further, when the wall member is installed on the floor member, the mounting work is usually performed from the inside of the water supply unit, so that the wall member is inserted into the wall mounting recess with the upper side inclined toward the inside of the water supply unit. To. Therefore, when the adhesive material is pressed against the wall member, it is possible to prevent the adhesive material from sliding in the horizontal direction with respect to the deformed material. As a result, it is possible to prevent the adhesive material from peeling off from the deformed material.

According to a sixth aspect of the present invention, in the fifth aspect of the present invention, the deformable material has a downwardly inclined portion having one side as a fixed end and inclined downward, and the other side having a free end which is inclined upward from the tip of the downwardly inclined portion. It is a water supply unit characterized by having the above-mentioned upwardly inclined portion.

According to this water supply unit, when the downward inclined portion is pressed against the wall member, the stress applied to the fixed end can be reduced, so that the life of the deformable material can be improved. On the other hand, the upwardly inclined portion can prevent the adhesive material pressed against the wall member from peeling off from the deformed material when the wall member is attached to the floor member.

A seventh aspect of the present invention is the water supply unit according to the first aspect, wherein the deformable material is integrally formed on the inner side surface of the wall-mounted recess.

According to this water supply unit, since the deformable material is integrated with the wall-mounted recess, the strength of the deformable material on the fixed end side can be improved.

An eighth invention is a water supply unit according to the second invention, wherein the deforming material is integrally formed on the side surface portion of the wall receiving member.

According to this water supply unit, since the deformable material is integrated with the wall receiving member, the strength of the deformable material on the fixed end side can be improved.

According to a ninth aspect of the invention, in the second or eighth invention, the side surface portion of the wall receiving member has a first side surface portion located on the floor portion side and a second side surface portion facing the first side surface portion. The first side surface portion has a rising portion that rises upward from the bottom surface portion, and a protruding portion that protrudes from the upper end of the rising portion toward the second side surface portion. The deformable material extends from the rising portion toward the second side surface portion, and the adhesive material has a gap between the deforming material and the rising portion in a state where the wall member is not inserted into the wall mounting recess. It is a water supply unit characterized by being provided on the deformable material.

According to this water supply unit, since the adhesive material can be inserted into the space between the wall member and the rising portion, the wall member can be arranged at a predetermined position of the wall mounting recess. Further, since the adhesive material closes the space between the wall member and the rising portion, watertightness can be effectively ensured.

According to the aspect of the present invention, there is provided a water supply unit capable of suppressing water from leaking from the inside of the unit to the outside of the unit.

It is sectional drawing which shows the seal member by the 3rd modification.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, similar components are designated by the same reference numerals and detailed description thereof will be omitted as appropriate.
FIG. 1 is a perspective view schematically showing a water supply unit according to the first embodiment.

The water supply unit 100 shown in FIG. 1 includes a floor member 10, a wall member 20, and a seal member 30. Further, the water supply unit 100 has a mounting structure 1 for the wall member 20.

In the example shown in FIG. 1, the water supply unit 100 is a bathroom. Therefore, the water supply unit 100 further has a bathtub 200. The bathtub 200 is installed on the bathroom installation surface F via the support legs 110. The water supply unit 100 is, for example, a household unit bath (system bath). The floor member 10 is, for example, a washing floor. The water supply unit 100 may be, for example, a unit bath for a hotel in which a toilet bowl, a vanity, or the like is mounted on the floor member 10. The floor member 10 may be the floor of a hotel bathroom or the like. The specific configuration of the water supply unit 100 is not limited to the example of FIG. 1, and can be changed as appropriate. For example, the water supply unit 100 may be a shower room or the like that does not have a bathtub 200.

The floor member 10 constitutes the floor surface of the water supply unit 100. The floor member 10 is formed in a shallow-bottomed vessel-like shape (pan shape) with its peripheral edge bent upward, and has waterproof property that prevents hot water from leaking to the outside of the unit. The floor member 10 is installed on the bathroom installation surface F via the support legs 110 having a structure whose height can be adjusted by rotating the bolt portion. The floor member 10 has a floor portion 11 and a wall mounting recess 12 provided on the outer peripheral side of the floor portion 11 on which the wall member 20 is placed.

The wall member 20 is inserted into the wall-mounted recess 12 of the floor member 10 and extends upward from the floor member 10. The wall member 20 is, for example, a door support frame 21 that supports a door that serves as an entrance / exit of the water supply unit 100. Further, the wall member 20 is, for example, a first surface portion 22 facing the door support frame 21. Further, the wall member 20 is, for example, a second surface portion 23 facing the bathtub 200. Further, the wall member 20 is, for example, a panel 24 located between the door support frame 21 and the bathtub 200 or between the first surface portion 22 and the bathtub 200. That is, the wall member 20 is a side wall of the water supply unit 100 that rises from the outer edge of the floor member 10. The wall member 20 has a steel plate 20a exposed inside the water supply unit 100 and a base material 20b (for example, gypsum board) fixed to the back surface side of the steel plate 20a.

FIG. 2 is a cross-sectional view of the floor member and the wall member in FIG. 1 as viewed from the direction of arrow AA.
FIG. 3 is a cross-sectional view showing a state when the wall member is inserted into the wall-mounted recess.

The floor member 10 has a floor portion 11 and a wall-mounted recess 12 provided along the outer edge of the floor portion 11. The floor portion 11 has a floor surface portion 11b on the upper surface 11a side. The floor surface portion 11b is a portion that is exposed inside the water supply unit 100 and is actually used as a washing place by the user.

The wall-mounted recess 12 is provided at the peripheral end of the floor portion 11 and is formed in a concave shape with an upper opening. The wall-mounted recess 12 is provided, for example, along the entire three sides (outer edges) of the floor portion 11 that are not adjacent to the bathtub 200. The wall-mounted recess 12 has an inner bottom surface 13 recessed below the upper surface 11a of the floor portion 11, and an inner side surface 14 extending upward from the inner bottom surface 13.

The inner bottom surface 13 extends along the outer edge of the floor portion 11 at a position one step lower than the upper surface 11a of the floor portion 11. The inner bottom surface 13 is a stepped surface having a step in the vertical direction by the regulating portion 15. The regulation unit 15 is provided on the side of the seal member 30 described later. The regulation unit 15 regulates the subduction of the wall member 20 by coming into contact with the wall member 20. The restricting portions 15 may be provided along the seal member 30, or may be provided in plurality at predetermined intervals in the length direction of the wall-mounted recesses 12. Further, the regulating portion 15 may be provided integrally with the wall-mounted recess 12 or may be provided separately. Further, the regulating portion 15 may protrude from the inner side surface 14 of the wall-mounted recess 12. That is, the regulating portion 15 may be provided at any position in the wall mounting recess 12 as long as the sinking of the wall member 20 can be regulated and does not interfere with the sealing member 30.

When the wall member 20 is installed in the wall mounting recess 12, the regulation unit 15 causes a part of the wall member 20 to be more than expected in the wall mounting recess 12 due to the inclination state of the floor member 10 and the manufacturing tolerance of the wall member 20. Even if it sinks, it regulates the sinking of the wall member 20. Therefore, the regulating unit 15 can prevent the deforming material 31 of the seal member 30, which will be described later, from being deformed beyond the allowable deformation amount.

The inner side surface 14 has a first inner side surface 14a located on the floor portion 11 side and a second inner side surface 14b facing the first inner side surface 14a. The first inner side surface 14a rises from the end of the inner bottom surface 13 on the floor portion 11 side toward the upper surface 11a of the floor portion 11. On the other hand, the second inner side surface 14b rises from the end portion of the inner bottom surface 13 opposite to the floor portion 11. The wall-mounted recess 12 has a dimension between the first inner side surface 14a and the second inner side surface 14b set corresponding to the thickness dimension of the wall member 20. Further, the wall mounting recess 12 is set to have a depth dimension from the upper surface 11a to the inner bottom surface 13 of the floor portion 11 so that the wall member 20 can be stably erected from the floor member 10.

Next, the seal member 30 will be described.

The seal member 30 is provided inside the wall-mounted recess 12. The seal member 30 extends continuously in the length direction of the wall-mounted recess 12. The seal member 30 is sandwiched between the wall-mounted recess 12 and the wall member 20, and watertightly closes the space between the wall-mounted recess 12 and the wall member 20. That is, the seal member 30 suppresses (seals) water from leaking from the inside of the water supply unit 100 to the outside through the wall-mounted recess 12. The seal member 30 has a deformable material 31 and an adhesive material 35.

The deformable material 31 is provided along the inner side surface 14 of the wall-mounted recess 12. That is, the deformable material 31 is provided so as to extend in the length direction of the inner side surface 14. The deformable material 31 is made of a resin material such as plastic or elastomer, and can be deformed by being pressed by the wall member 20. Deformability in this case includes both plastic deformation and elastic deformation. Further, the deformation of the deformable material 31 includes both a case where the deformable material 31 is deformed as a whole and a case where the material itself of the deformable material 31 is deformed. The deformable material 31 of the present embodiment is elastically deformable.

The deformable material 31 is formed of, for example, a thin plate material, and is provided at a position having a height dimension L from the inner bottom surface 13 of the wall-mounted recess 12. The height dimension L is preferably set above, for example, the height of the regulating portion 15. That is, since the deformable material 31 is pressed from above by the wall member 20, it is preferable that the deformable material 31 is provided above the regulating portion 15 (on the opening side of the wall-mounted recess 12). If the upper surface of the adhesive material 35, which will be described later, is located above the regulating portion 15, the deformable material 31 is pressed via the adhesive material 35. In other words, the height dimension L of the deformable material 31 is set to a height that is pressed by the wall member 20 and elastically deforms downward.

The deformable material 31 has one side 31a provided on the inner side surface 14 and the other side 31b extending toward the inside of the wall-mounted recess 12. Specifically, the deformable material 31 extends in a straight line from the first inner side surface 14a toward the second inner side surface 14b. In this case, the deformable material 31 has a fixed end on one side 31a (first inner side surface 14a side) and a free end on the other side 31b (second inner side surface 14b side).

As a result, the deformable material 31 can be elastically deformed in the vertical direction. As shown in FIG. 3, the deformable material 31 is pressed by the wall member 20 and elastically deforms so as to apply an upward urging force. Therefore, when the wall member 20 is inserted into the wall-mounted recess 12, the sealing member 30 is pressed toward the inner bottom surface 13 on the other side 31b (free end side) of the deformable member 31. Further, when the wall member 20 is removed from the wall-mounted recess 12, the deformable material 31 is restored to the original state (the state shown in FIG. 3) by an urging force. In this case, the deformable material 31 is integrally formed on the inner side surface 14 (first inner side surface 14a) of the wall-mounted recess 12. As a result, since the deformable material 31 is integrated with the wall-mounted recess 12, the strength of one side 31a (fixed end side) of the deformable material 31 is improved. The deformable material 31 may be adhered to the inner side surface 14 of the wall-mounted recess 12.

The upper surface 31c of the deformable material 31 is formed in an uneven shape. In this case, the entire upper surface 31c of the deformable material 31 may be formed in an uneven shape, or a part of the upper surface 31c may be formed in an uneven shape. The adhesive material 35 is fixed to the uneven upper surface 31c. As a result, the contact surface (adhesive surface) between the upper surface 31c of the deformable material 31 and the adhesive material 35 can be enlarged. Therefore, when the wall member 20 is removed from the wall-mounted recess 12, the adhesive material 35 can be prevented from peeling from the deformed material 31. Further, when the wall member 20 is inserted into the wall mounting recess 12 and the adhesive material 35 is pressed against the wall member 20, it is possible to prevent the adhesive material 35 from sliding in the horizontal direction with respect to the deformed material 31. As a result, it is possible to prevent the adhesive material 35 from peeling off from the deformable material 31. In the example shown in FIG. 3, the upper surface 31c of the deformable material 31 is formed in a curved shape, but the present invention is not limited to this, and for example, the upper surface 31c of the deformable material 31 may have a hole recessed downward. Good.

The adhesive material 35 is provided on the upper surface 31c of the deformable material 31. The pressure-sensitive adhesive 35 has adhesiveness and elasticity. The pressure-sensitive adhesive 35 is formed of, for example, a pressure-sensitive adhesive. The adhesive material 35 does not completely dry even after a lapse of time, and is always a material having adhesiveness. Therefore, it is completely different from the so-called adhesive, which dries completely over time and loses its adhesiveness (adhesiveness approaches zero infinitely).

Further, since the adhesive material 35 has elasticity, even if the wall member 20 is removed from the wall-mounted recess 12, the adhesive material 35 is restored to its original shape by this elasticity. Therefore, the wall member 20 can be attached to the adhesive material 35 again. That is, the adhesive material 35 can be detachably adhered to the wall member 20. The adhesive material 35 may be, for example, a gel (gel-like substance) having adhesiveness and elasticity.

As described above, the seal member 30 has a two-layer structure of the deformable material 31 and the adhesive material 35. In this case, as shown in FIG. 3, the vertical thickness dimension H1 of the deformable material 31 is smaller than the vertical thickness dimension H2 of the adhesive material 35 (H1 <H2). The thickness dimension H1 of the deformable material 31 and the thickness dimension H2 of the adhesive material 35 are subjected to experiments and simulations based on the depth dimension of the wall-mounted recess 12, the specifications of the wall member 20, the strength of the deformable material 31, the amount of elastic deformation, and the like. Is set by. Thereby, the crimping force between the wall member 20 and the adhesive material 35 can be adjusted by the elastic deformation of the deformable material 31. Therefore, the adhesive strength of the adhesive material 35 can satisfy the balance between the water stoppage and the removal of the wall member 20. As a result, the adhesive material 35 of the seal member 30 is excellent in peelability from the wall member 20, so that the workability of the attachment / detachment work of the wall member 20 can be improved.

The caulking material 40 is provided at a corner portion (boundary portion) between the floor portion 11 and the wall member 20. The caulking material 40 is applied on-site after the wall member 20 is inserted into the wall-mounted recess 12. The caulking material 40 is made of, for example, silicone, and prevents water from entering the wall-mounted recess 12 from the floor portion 11.

The wall member mounting structure 1 according to the present embodiment has the above-described configuration, and next, the work of assembling the wall member 20 into the wall-mounted recess 12 will be described.

First, as shown in FIG. 3, the wall member 20 is inserted into the wall-mounted recess 12 of the floor member 10 from the room of the water supply unit 100. After that, the caulking material 40 is applied to the corner portion between the floor portion 11 and the wall member 20.

Here, since the coating work of the caulking material 40 is performed after the wall member 20 is assembled to the floor member 10, the accuracy thereof is left to the construction technique of the on-site builder. That is, if the construction technique of the on-site builder is not sufficient, there is a risk that the caulking material 40 may be forgotten to be applied or the caulking material 40 may not be applied correctly, and watertightness may not be ensured. ..

Therefore, a configuration is conceivable in which a seal member is provided between the wall member 20 and the wall mounting recess 12. However, the amount of gap between the wall member 20 and the wall-mounted recess 12 varies due to the influence of product errors of each member, the tilted state of the floor member 10, and the like. In this case, in a place where the amount of gap between the wall member 20 and the wall mounting recess 12 is large, sufficient pressure may not be applied to the sealing member, and the sealing property may be insufficient. Further, in order to ensure the sealing property, it is conceivable to form a large height of the sealing member in consideration of a large gap amount. However, since the wall member 20 is inserted into the wall mounting recess 12 from the inside of the water supply unit 100, the seal member may fall outward, and the arrangement of the wall member 20 may become unstable.

Therefore, in the present embodiment, the seal member 30 having the deformable material 31 and the adhesive material 35 is provided in the wall-mounted recess 12 of the floor member 10. The seal member 30 is provided in the wall-mounted recess 12 at the factory. As a result, when the wall member 20 is inserted into the wall-mounted recess 12, watertightness can inevitably be obtained between the wall member 20 and the wall-mounted recess 12. Therefore, even if there is a defect in the application work of the caulking material 40 at the site, the sealing member 30 can prevent water from leaking from the room to the outside of the water supply unit 100.

The seal member 30 has a two-layer structure consisting of a deformable material 31 and an adhesive material 35. The deformable material 31 is elastically deformed downward by being pressed by the wall member 20, and can absorb the amount of gap between the wall-mounted recess 12 and the wall member 20. Therefore, the adhesive material 35 can obtain an appropriate compressive force from the wall member 20 regardless of the size of the gap amount.

Further, the adhesive material 35 provided on the upper surface 31c of the deformable material 31 can effectively seal between the wall member 20 and the wall-mounted recess 12. In this case, even in a place where the gap amount between the wall member 20 and the wall mounting recess 12 is large, the deformation amount of the deformable material 31 changes, so that the sealing property can be firmly maintained. In addition, the seal member 30 extends from the inner surface 14 of the wall-mounted recess 12. Therefore, even in various wall-mounted recesses 12 having different depth dimensions, the same sealing member 30 can be used only by adjusting the mounting height of the sealing member 30. Therefore, since the thickness dimension of the seal member 30 can be reduced, the seal member 30 is excellent in stability, and even if the gap amount between the wall member 20 and the wall mounting recess 12 changes, watertightness is ensured. Can be done.

Further, the deformable material 31 can be elastically deformed in the vertical direction by having one side 31a as a fixed end and the other side 31b as a free end, and the vertical thickness dimension H1 of the deformable material 31 is the adhesive material 35. It is smaller than the vertical thickness dimension H2 (H1 <H2). In this case, the crimping force between the wall member 20 and the adhesive material 35 can be adjusted by the elastic deformation of the deformable material 31. As a result, the adhesive strength of the adhesive material 35 can satisfy the balance between the water stoppage and the removal of the wall member 20. Therefore, since the adhesive material 35 of the seal member 30 is excellent in peelability from the wall member 20, the workability of the wall member 20 attachment / detachment work can be improved.

Further, the upper surface 31c of the deformable material 31 is formed in an uneven shape. As a result, the contact surface (adhesive surface) between the deformable material 31 and the adhesive material 35 can be enlarged. Further, as shown in FIG. 3, the wall member 20 is inserted obliquely into the wall-mounted recess 12 from the indoor side of the water supply unit 100. Therefore, the adhesive material 35 is pressed horizontally from the wall member 20 toward the second inner side surface 14b side. Since the uneven upper surface 31c of the deformable material 31 can suppress the pressing force in the horizontal direction, it is possible to prevent the adhesive material 35 from sliding in the horizontal direction with respect to the deformable material 31. As a result, it is possible to prevent the adhesive material 35 from peeling off from the deformable material 31.

Further, a regulating portion 15 is further provided on the side of the seal member 30. The regulation unit 15 regulates the subduction of the wall member 20 by coming into contact with the wall member 20. As a result, even when a part of the wall member 20 tries to sink into the wall mounting recess 12 more than expected due to the inclination state of the floor member 10 or the manufacturing tolerance of the wall member 20, the regulating portion 15 of the wall member 20 Regulate subduction. Therefore, it is possible to prevent an excessive load from being applied to the deformable material 31. In other words, it is possible to prevent the deformable material 31 from being deformed beyond the allowable deformation amount.
