  In this way, when the convex portion formed on the back side of the peripheral wall member and the upper surface fixing portion of the connection fitting are fixed by the first connector extending in the direction intersecting the upper surface of the convex portion, the convex portion is formed on the upper surface fixing portion. If there is a gap between the inner surface of the first penetrating portion and the outer surface of the first connector passing through the first penetrating portion, the peripheral wall member can be relatively moved within the range of this gap. That is, the relative position of the peripheral wall member with respect to the waterproof pan (the relative position in the direction of the upper surface of the convex portion) can be finely adjusted and fixed. Further, the side surface of the waterproof pan or the lower member and the side surface fixing portion of the connecting fitting are fixed by a second connecting tool extending in a direction intersecting the side surface. In this configuration, if there is a gap between the inner surface of the second penetrating portion formed in the side surface fixing portion and the outer surface of the second connector passing through the second penetrating portion, the waterproof pan is relatively moved within this gap range. can do. That is, it becomes possible to fix the waterproof pan relative to the peripheral wall member while finely adjusting the relative position (the relative position in the side surface direction). Since the positional relationship between the peripheral wall member and the waterproof pan can be finely adjusted and fixed in the two plane directions in this manner, even if manufacturing variations such as warpage or twist occur in the waterproof pan or the peripheral wall member, fine adjustment is possible. By this, it becomes possible to fix them while suppressing their influence.

Further, the upper wall panel 120 whose lower end surface is adjacent to the adjacent portion 72 of the wall portion 60C is also formed in a plate shape and the plate surface is arranged parallel to the vertical direction. For example, the inner surface (plate surface) is the wall portion 60C. Is flush with the inner wall surface of the inner wall portion 62 of the bathtub.

  Next, a fixing structure for fixing the connecting member 60 to the peripheral portion of the bathtub 5 will be described. Although the fixing structure of the wall portion 60B and the peripheral portion 7B will be described below with reference to FIG. 8, the fixing structure of the wall portion 60A and the peripheral portion 7A and the fixing structure of the wall portion 60C and the peripheral portion 7C will also be described. It has the same structure as in FIG.

  As shown in FIG. 8, the wall portion 60B of the connecting member 60 is arranged so as to be placed on the peripheral edge portion 7B of the bathtub 5. The peripheral edge portion 7B of the bathtub 5 has a support portion 8A that supports the wall portion 60B while mounting it, and a rib-shaped rising wall 8B that rises upward from the support portion 8A. The support portion 8A has an upper surface of a predetermined width that is horizontal and flat, and such an upper surface continues in a shape extending in the left-right direction. Further, the peripheral wall 7B is formed with a falling wall 8C that extends downward from the support 8A.

  As shown in FIG. 8, a bent portion 63 is formed at the lower end of the bathtub-side inner wall portion 62 so as to be bent substantially at a right angle to the wall surface of the bathtub-side inner wall portion 62 and extends to the back surface side. A convex portion 64 that protrudes from the back surface of the bathtub-side inner wall portion 62 is formed at a position close to the upper portion of the bent portion 63. The convex portion 64 is, for example, a portion formed by bonding wood, a metal member, a resin member, or the like to the back surface of the bathtub-side inner wall portion 62 with an adhesive medium or the like.

  The peripheral edge portion 7B of the bathtub 5 is arranged below the convex portion 64 formed on the back surface portion of the bathtub-side inner wall portion 62. Then, the bent portion 63 of the wall portion 60B is placed on the upper surface of the support portion 8A, and in the gap between the lower surface of the bent portion 63 and the upper surface of the support portion 8A, a silicon seal for sealing this gap. The material 9 is filled. In such a mounted state, the bathtub 5 and the connecting member 60 are fixed in a form of being connected by a connecting fitting 76. The connection fitting 76 includes a contact portion 76A that contacts the end surface of the convex portion 64, a contact portion 76B that contacts the wall surface of the falling wall 8C, and a connection portion 76C that connects these contact portions 76A and 76B, The contact portions 76A and 76B are fixed to the convex portion 64 and the falling wall 8C by fasteners 78A and 78B such as screw members.

  As described above, the bathroom unit 1 of this configuration is configured as a separate member in which the waterproof pan 20 that forms the wash floor 22 and the waist high walls 40 and 41 that form the inner wall of the wash floor are divided. According to this configuration, the washing floor 22 and the waist high walls 40 and 41 can be configured by separate members, respectively, and the restrictions caused by integrally molding these are alleviated.

  In particular, the degree of freedom in selecting the materials and shapes of the wash floor 22 and the inner wall 42 of the wash floor is increased, and it is easy to increase the variation of the combination of the floor 22 of the wash floor and the inner wall 42 of the wash floor. In addition, since the wash floor 22 and the inner wall of the wash floor are divided, it is necessary to change the wash floor 22 and the inner wall at once when some design changes are required such as changing the position of the door. Instead, it becomes easier to deal with design changes in smaller parts. For example, when the design of the configuration of FIG. 1 is changed to the configuration shown in FIG. 9 described later (the configuration in which the position of the door is changed from FIG. 1), only a part of the design change is necessary, and it is easy to reduce the manufacturing cost. .

  Further, in this configuration, unlike the configuration in which the floor of the washing area and the peripheral wall are integrally molded, it is not necessary to provide a draft in the peripheral wall. That is, since there is no restriction (a restriction that the inner wall of the peripheral wall portion is inclined at a slight obtuse angle with respect to the floor portion) required for integral molding, the inner wall surface of the wash floor 22 is the same as the above-mentioned wash floor inner wall portion 42. It is also possible to form it substantially perpendicular to the plane. Further, the wall surfaces of the waist high walls 40 and 41 and the wall surface of the upper wall panel 120 can both be vertical planes and can be flush with each other. With such a configuration, designability can be improved.

  Further, the bathroom unit 1 is provided on the bathtub-side inner wall portion 62 that rises from the peripheral portion of the bathtub 5 that does not face the washing floor 22 side, and is provided on the upper end portion of the bathtub-side inner wall portion 62 and the upper wall panel is provided above. It has the connecting member 60 provided with the 2nd wall arrangement | positioning part 70 in which 120 is arrange | positioned. Then, the height of the upper end of the washroom inner wall portion 42 and the height of the upper end of the bathtub side inner wall portion 62 are aligned. According to this structure, even if the heights of the upper end of the inner wall 42 of the washroom and the upper surface of the bathtub 5 are different from each other, the upper end of the inner wall 42 of the washroom and the upper end of the inner wall 62 of the bathtub are aligned to have a uniform design. Can be In addition, the upper wall panel 120 on the washroom side and the upper wall panel 120 on the bathtub 5 side can be more easily matched in height with each other, so that the design can be further enhanced.

  In addition, the wall placement part 50 is formed along the upper edge of the inner wall part 42 of the washroom, and has an upper surface configured as an adjacent surface adjacent to the end surface of the upper wall panel, and a wall that rises upward from the adjacent part 52. And a standing wall portion 54 which is formed along the adjacent portion 52 and is arranged on the back surface side of the upper wall panel 120. According to this configuration, the position can be determined by a proximity structure in which the end surface of the upper wall panel 120 is adjacent to the upper surface (adjacent surface) of the adjacent portion 52 and the back surface of the upper wall panel 120 is adjacent to the standing wall portion 54. Then, in the vicinity of the boundary between the upper wall panel 120 and the waist high walls 40, 41, it becomes easier to prevent water from flowing around to the back surface side.

  In addition, the bathroom unit 1 has a plate-shaped upper surface fixing portion 81 having a first penetrating portion 82 formed therein and a side surface having a plate-like shape bent from the upper surface fixing portion 81 and having a second penetrating portion 86 formed therein. It has a connecting fitting 80 provided with a fixing portion 84. Then, a convex portion 44 is formed on the back surface of the inner wall portion 42 of the washing place, and the side surface portion of the waterproof pan 20 is arranged below the convex portion 44. Then, the upper surface fixing portion 81 is fixed to the upper surface of the convex portion 44 by the first connector 91 which is passed through the first penetrating portion 82 and extends in the direction intersecting the upper surface of the convex portion 44, and is passed through the second penetrating portion 86. Moreover, the side surface fixing portion 84 is fixed to the side surface of the lower member (annular frame 14C) arranged below the waterproof pan 20 by the second connector 92 extending in the direction intersecting the side surface of the waterproof pan 20.

  In this way, when the convex portion 44 formed on the back side of the waist high walls 40 and 41 and the upper surface fixing portion 81 of the connection fitting 80 are fixed by the first connector 91 extending in the direction intersecting the upper surface of the convex portion 44. If there is a gap between the inner surface of the first penetrating portion 82 formed on the upper surface fixing portion 81 and the outer surface of the first connector 91 that passes through the first penetrating portion 82, the waist high walls 40 and 41 are set in the range of this gap. Can move relatively. In other words, it is possible to fix the waist height walls 40, 41 relative to the waterproof pan 20 (relative position in the direction of the upper surface of the convex portion 44) while finely adjusting them. Further, the side surface of the lower member (annular frame 14C) and the side surface fixing portion 84 of the connecting fitting 80 are fixed by a second connecting member 92 extending in a direction intersecting the side surface. In this configuration, if there is a gap between the inner surface of the second penetrating portion 86 formed on the side surface fixing portion 84 and the outer surface of the second connecting member 92 that passes through the second penetrating portion 86, the waterproof pan 20 will fall within this gap. Can be moved relative to each other. That is, it is possible to finely adjust and fix the relative position (relative position in the side direction) of the waterproof pan 20 to the waist high walls 40 and 41. In this way, the positional relationship between the waist high walls 40 and 41 and the waterproof pan 20 can be fixed while finely adjusting in the two plane directions, so that the waterproof pan 20 and the waist high walls 40 and 41 can be manufactured with no warp or twist. Even if variations occur, it is possible to fix them in a form that suppresses their influence by fine adjustment.
