As shown in FIG. 2, the drain plug portion 12 includes a plug lid 20, a drain port member 22, an operation portion 24, and an attachment member 26. The plug lid 20 is attached to the drain outlet 102 of the bathtub 100 from above (inside the bathtub) and closes the drain outlet 102 from above. The plug lid 20 closes the drain port portion 102 by contacting the peripheral edge portion 102b of the drain port portion 102, for example.

  The plug lid 20 has a packing 21, for example. The packing 21 is provided in an annular shape on the outer edge of the stopper lid 20. For the packing 21, for example, an elastic material such as rubber is used. The plug lid 20 closes the drain port portion 102 by bringing the packing 21 into contact with the peripheral edge portion 102 b of the drain port portion 102. Thereby, the drain outlet 102 can be closed more reliably. The plug lid 20 may be in direct contact with the peripheral edge portion 102b of the drain port portion 102, or may be in indirect contact with the packing 21 or the like. Moreover, the position (position which touches) the drain port part 102 is not restricted to the peripheral part 102b, For example, the inner edge part of the drain port 102a, the upper end part of the drain port member 22, etc. may be sufficient.

  The shape of the drain outlet 102 viewed from above is substantially circular. The drain port 102a has, for example, a substantially circular through hole shape. The plug lid 20 is a plug having a substantially circular cross section corresponding to the shapes of the drain port 102 and the drain port 102a. The cross-sectional shape of the drain port 102 is not limited to a circle, and may be an arbitrary shape such as an ellipse or a polygon. The shape of the lid 20 may be any shape that can close the drain port 102 from above.

  The drain port member 22 is inserted into the drain port 102 a of the drain port portion 102 and the pipe 200, and connects the pipe 200 to the bathtub 100. The operation part 24 supports the plug lid 20 so as to be movable up and down. The attachment member 26 installs the operating part 24 at the drain outlet 102a. The attachment member 26 is attached, for example, in the pipe 200 and holds the operating unit 24. The operating unit 24 is attached to the drain port 102a via the attachment member 26, and opens and closes the drain port 102a by moving the plug lid 20 up and down. For example, the attachment member 26 may be attached to the drain port 102.

  The operating unit 24 includes a case 24a and a support shaft 24b. Case 24a is cylindrical. The case 24a is attached to the drain port 102a (the pipe 200) with its axis directed in the vertical direction. The support shaft 24b is inserted into the case 24a and is held by the case 24a so as to be movable along the axial direction of the case 24a. The support shaft 24b moves vertically when the case 24a is attached to the drain port 102a.

  The upper end of the support shaft 24b protrudes above the upper end of the case 24a. The plug lid 20 is attached to the upper end of the support shaft 24b. The operating unit 24 supports the plug lid 20 at the upper end of the support shaft 24b. In this manner, the support shaft 24 b is provided so that the stopper lid 20 is attached to the upper end and is movable up and down relative to the bathtub 100.

The through hole 202 is provided below the drain plug portion 12 in the pipe 200. The release wire 16 is inserted into the pipe 200 through the through hole 202 and connected to the operating unit 24. Further, the through hole 202 is closed by, for example, the hose 18 or the like. Thereby, water leakage from the through hole 202 is suppressed.

  When the movable portion 14b of the operation portion 14 is in the first position, the support shaft 24b is held at a position where the plug lid 20 blocks the drain port portion 102 as shown in FIG. When the movable part 14b of the operation part 14 moves from the first position to the second position, the inner wire of the release wire 16 is sent to the drain plug part 12 side according to the amount of movement of the movable part 14b. Therefore, when the movable portion 14b moves to the second position, the support shaft 24b of the operating portion 24 protrudes from the case 24a rather than the state shown in FIG. Thereby, when the movable part 14b of the operation part 14 exists in a 2nd position, the stopper lid 20 moves upward with the movement of the support shaft 24b, and the drain port part 102 is open | released.

  As described above, the operating unit 24 moves the support shaft 24b in accordance with the operation of the operation unit 14, so that the plug lid 20 closes the drain port portion 102 (the state illustrated in FIG. 2), and the plug lid The support shaft 24b is switched to a lifted state in which 20 is spaced upward from the drain port portion 102 and opens the drain port portion 102. In other words, the operation unit 14 switches the support shaft 24b between the lowered state and the raised state.

Fig.5 (a) and FIG.5 (b) are the perspective views showing the action | operation part and attachment member which concern on embodiment.
FIG. 6A and FIG. 6B are top views showing the operation unit and the attachment member according to the embodiment.
As shown in FIGS. 5A, 5B, 6A, and 6B, the attachment member 26 includes a holding portion 40, a connecting portion 42, a pedestal portion 44, Have

  The holding part 40 is cylindrical, and holds the operating part 24 by accommodating the operating part 24 in an internal space. In this example, the holding unit 40 holds the operating unit 24 directly. For example, the holding unit 40 may hold the operating unit 24 indirectly via another member.

  The connecting portion 42 extends outward from the holding portion 40. For example, the connecting portion 42 extends radially from the outer surface of the holding portion 40 toward the outside. The connecting portion 42 is integral with the holding portion 40. The attachment member 26 has, for example, a plurality of connecting portions 42. In this example, the attachment member 26 has the three connection parts 42 of the connection parts 42a-42c. The number of connecting portions 42 is not limited to three, but may be one or two, or four or more.

  The pedestal portion 44 is integral with the connecting portion 42. The pedestal portion 44 is integral with each of the plurality of connecting portions 42, for example. The pedestal portion 44 has a cylindrical shape provided so as to surround the holding portion 40. The pedestal portion 44 is attached to the pipe 200. Thereby, the base part 44 attaches the operation | movement part 24 hold | maintained at the holding | maintenance part 40 and the holding | maintenance part 40 to the drain port 102a. The pedestal 44 may be attached to the drain outlet 102a (drain outlet 102). That is, the pedestal portion 44 is attached to the drain port 102 a or the pipe 200.

  The pedestal portion 44 surrounds a part of the holding portion 40 when viewed from above (viewed from above). The pedestal portion 44 has a cylindrical shape having a width (diameter) larger than that of the holding portion 40. The pedestal part 44 is disposed substantially coaxially with the cylindrical holding part 40, for example. Thereby, a part of holding | maintenance part 40 can be enclosed by the base part 44 in the state seen from upper direction.

  In this example, the pedestal part 44 surrounds a part of the holding part 40 even when viewed from the side (side view). For example, the holding portion 40 may be disposed above the pedestal portion 44 in a state viewed from the side by increasing the length of the connecting portion 42 in the vertical direction. In the state seen from the side, the pedestal portion 44 does not necessarily surround a part of the holding portion 40. That is, the pedestal portion 44 is provided so as to surround the holding portion 40 at least when viewed from above.

  The pedestal 44 is attached below the drain port member 22 in the pipe 200 (see FIG. 2). The pedestal portion 44 is mounted in the pipe 200 by being placed on the placement portion 220.

Further, the pedestal portion 44 is restrained from moving upward by being pressed downward by the drain port member 22. In other words, the base portion 44 is sandwiched between the placement portion 220 and the drain port member 22 in the pipe 200.

  The pedestal portion 44 has a restriction portion 45. The pedestal part 44 restricts the rotation of the attachment member 26 in the pipe 200 in the horizontal direction by bringing the restriction part 45 into contact with the inner surface of the second pipe part 212 of the pipe 200 from the side (see FIG. 2).

  As described above, the attachment member 26 is placed on the placement portion 220 in the pedestal portion 44. The first storage space 221 of the pipe 200 stores the base portion 44 of the attachment member 26. The attachment member 26 is attached to the inside of the pipe 200 via the pedestal part 44, thereby arranging the operating part 24 and the holding part 40 at predetermined positions in the pipe 200.

  The holding part 40 includes a first main body part 51 and a first opening part 51a. The 1st main-body part 51 is cylindrical. The first opening 51 a is provided on the side of the first main body 51, and allows the operation unit 24 to be inserted into the first main body 51 in the horizontal direction from the side. The inner diameter of the first main body portion 51 is set to be substantially the same as or slightly smaller than the outer diameter of the operating portion 24. Thereby, the operation part 24 inserted into the first main body part 51 is fitted into the first main body part 51. The holding part 40 holds the operating part 24 by fitting the operating part 24 and the first main body part 51, for example.

  The pedestal 44 has a second main body 52 and a second opening 52a. The 2nd main-body part 52 is cylindrical. The second opening 52 a is provided on the side of the second main body 52, and allows the operation unit 24 to be inserted into the second main body 52 in the horizontal direction from the side.

  At least a part of the second opening 52a faces the same direction as at least a part of the first opening 51a in the horizontal direction. In this example, the entire first opening 51a faces the same direction as a part of the second opening 52a. When viewed from the side, the entire first opening 51a is exposed through the second opening 52a. The minimum lateral width W2 (opening width) of the second opening 52a is larger than the minimum lateral width W1 of the first opening 51a, and the second main body 52 does not overlap the first opening 51a in the horizontal direction. Thereby, when the operation part 24 is inserted / removed with respect to the 1st main-body part 51, it can suppress that the 2nd main-body part 52 becomes obstructive. The operation part 24 can be easily inserted into and removed from the first main body part 51. For example, a part of the second main body part 52 may overlap with a part of the first opening 51a in the horizontal direction as long as the insertion and removal of the operating part 24 is not significantly hindered. The first opening 51a may have a portion that faces a different direction from the second opening 52a.

  The minimum lateral width W2 of the second opening 52a is larger than the maximum lateral width Ws of the operating part 24. On the other hand, the minimum lateral width W1 of the first opening 51a is smaller than the maximum lateral width Ws of the operating unit 24. For the attachment member 26, for example, a resin material such as polypropylene is used. The attachment member 26 has elasticity. Thereby, in the holding | maintenance part 40, the 1st main-body part 51 can be temporarily deform | transformed so that the 1st opening part 51a may be expanded.

  At the lower end of the first main body 51, a pair of ribs 51r are provided so as to face each other with the opening 51a interposed therebetween. Each rib 51r protrudes inward of the first main body 51. A groove 24c is provided in the case 24a of the operating unit 24. The groove 24c is provided in the vicinity of the lower end of the case 24a, and is formed in a concave shape that is recessed inward from the side surface of the case 24a. The shape of the groove 24c corresponds to the shape of each rib 51r.

  When the operating unit 24 is held by the holding unit 40, the operating unit 24 is inserted into the second opening 52 a from the side, and then pressed against the first opening 51 a in the horizontal direction, so that the first main body 51 The first opening 51a is expanded by elastically deforming. And the action | operation part 24 is inserted into the 1st main-body part 51 from the side from the extended 1st opening part 51a. At this time, each rib 51r is fitted into the groove 24c. As a result, the operating part 24 is inserted into the first main body part 51, and the vertical movement of the operating part 24 is restricted by the engagement of each rib 51r and the groove 24c. In other words, the engagement of each rib 51r and the groove 24c suppresses the operating part 24 from coming off from both ends of the first main body part 51 in the axial direction. As a result, the operating unit 24 is held by the holding unit 40.

  A connecting portion 42 a that is one of the plurality of connecting portions 42 extends from one side end portion 51 b of the first main body portion 51 toward the pedestal portion 44. A connecting portion 42 b that is another one of the plurality of connecting portions 42 extends from the other side end portion 51 c of the first main body portion 51 toward the pedestal portion 44.

  Further, the connecting portion 42 a extends toward one side end portion 52 b of the second main body portion 52. The connecting portion 42 b extends toward the other side end portion 52 c of the second main body portion 52. That is, the connecting portion 42 a extends from the side end portion 51 b of the first main body portion 51 toward the side end portion 52 b of the second main body portion 52. The connecting portion 42 b extends from the side end portion 51 c of the first main body portion 51 toward the side end portion 52 c of the second main body portion 52.

  One side end 52b of the second main body 52 protrudes from the connecting portion 42a toward the second opening 52a. On the other hand, the other side end portion 52c of the second main body portion 52 is substantially flush with the side surface of the connecting portion 42b. In other words, the side end portion 52c does not protrude toward the second opening 52a side than the connecting portion 42b.

  On the contrary, the side end portion 52b may be substantially flush with the side surface of the connecting portion 42a, and the side end portion 52c may protrude from the connecting portion 42b to the second opening 52a side. Or you may make both the side edge parts 52b and 52c protrude from the connection part 42 to the 2nd opening part 52a side. That is, at least one of the side end portion 52b and the side end portion 52c may protrude from the connecting portion 42 to the second opening 52a side.

  The protruding amount of the side end portions 52b and 52c is, for example, 10 mm or less. The state in which the connecting portion 42a extends toward the side end portion 52b is, for example, a state in which the distance between the side end portion 52b and the connecting portion 42a is 10 mm or less. The state where the connecting portion 42b extends toward the side end portion 52c is, for example, a state where the distance between the side end portion 52c and the connecting portion 42b is 10 mm or less.

  The connecting portion 42c extends from the side of the first main body 51 opposite to the first opening 51a toward the pedestal 44 toward the opposite side of the first opening 51a.

  When attaching the drain plug portion 12 of the drain plug device 10 to the bathtub 100 and the pipe 200, first, the pipe 200 is installed at a predetermined position in the bathroom. The operating unit 24 is connected to one end of the release wire 16 in advance. Then, one end of the operating unit 24 and the release wire 16 is inserted into the pipe 200 through the through hole 202. After inserting the operation part 24, the support shaft 24b is exposed from the opening end 211a.

  After the operating part 24 is taken out above the pipe 200, the operating part 24 is inserted from the second opening 52a into the second main body 52 from the side, and the first opening 51a is inserted into the first main body 51. The operating unit 24 is inserted into the holding member 40 of the attachment member 26 by inserting the operating unit 24 from the side.

  Thereafter, the pedestal portion 44 of the attachment member 26 is inserted into the pipe 200. The pedestal part 44 is inserted into the pipe 200 until it is placed on the placement part 220. In other words, the pedestal portion 44 is inserted into the pipe 200 until it contacts the placement portion 220. Then, the pedestal portion 44 is installed in the pipe 200 by inserting the restriction portion 45 into the second pipe portion 212 of the pipe 200. Thereby, the operation part 24 is installed in the pipe 200.

  After the operation part 24 is installed in the pipe 200, the positions of the opening end 211 a and the drain port part 102 are aligned, and the bathtub 100 is installed on the pipe 200. In this case, the operating unit 24 is exposed upward through the drain port 102a.

  After installing the bathtub 100, the drain port member 22 is inserted through the drain port 102a and the pipe 200 from above. Then, the male screw portion 22c of the drain port member 22 is screwed into the female screw portion 214 of the pipe 200, and the bathtub 100 is sandwiched between the flange portion 22b and the pipe 200, whereby the bathtub 100 and the pipe are connected via the drain port member 22. 200 is connected. Further, the pedestal 44 is prevented from moving upward by sandwiching the pedestal 44 between the drain port member 22 and the mounting portion 220.

  Thereafter, the stopper lid 20 is attached to the upper end of the support shaft 24 b of the operating portion 24. Thus, the attachment of the drain plug portion 12 of the drain plug device 10 is completed. The operation unit 14 may be attached to the rim surface 104 of the bathtub 100 in advance before the drain plug portion 12 is attached, or after the drain plug portion 12 is attached. You may attach to.

  As described above, according to the drain plug device 10 according to the present embodiment, since the holding portion 40, the connecting portion 42, and the pedestal portion 44 of the attachment member 26 are respectively integrated, the holding portion 40 and the pedestal portion are included. Compared with the case where 44 is comprised separately, a structure can be simplified. Thereby, the assembling work can be simplified, the number of parts can be reduced, and the manufacturing cost can be reduced. In addition, since at least a part of the second opening 52a faces in the same direction as at least a part of the first opening 51a in the horizontal direction, the operating part 24 is located on the side of the pedestal 44 and the holding part 40. Can be inserted horizontally from one direction. Thereby, even when the holding part 40, the connection part 42, and the base part 44 are integrated, the operation part 24 can be easily attached to the holding part 40. Accordingly, it is possible to provide the drain plug device 10 that can be easily assembled with a simple configuration.

  In the drain plug device 10, the minimum lateral width W <b> 2 of the second opening 52 a is larger than the maximum lateral width Ws of the operating unit 24. Thereby, when inserting the action | operation part 24 into the base part 44 from a side, it is not necessary to spread the base part 44, and an assembly operation | work can be made easier.

  In the drain plug device 10, the connecting portion 42 a extends from the one side end portion 51 b of the first main body portion 51 toward the pedestal portion 44, and the connecting portion 42 b is the other side end portion of the first main body portion 51. 51c extends toward the pedestal 44. Thereby, after inserting the operation part 24 into the 2nd opening part 52a, when inserting in the 1st opening part 51a from a side, the operation part 24 is guided to the 1st opening part 51a by two connection parts 42a and 42b. can do. Thereby, position adjustment with respect to the 1st opening part 51a of the action | operation part 24 can be made easy, and it can make it easy to insert the action | operation part 24 in the 1st opening part 51a. Therefore, the assembling work can be simplified.

  In the drain plug device 10, the connecting portion 42 a extends toward one side end portion 52 b of the second main body portion 52, and the connecting portion 42 b extends toward the other side end portion 52 c of the second main body portion 52. Extend. Thereby, when removing the action | operation part 24 from the holding | maintenance part 40, the width of the 1st opening part 51a and the 2nd opening part 52a can be expanded by pushing the side surface of the two connection parts 42a and 42b outward. it can. Thereby, the action | operation part 24 can be made easy to remove from the holding | maintenance part 40, and the operation | work of removal can also be simplified.

  Further, in the drain plug device 10, one side end portion 52b of the second main body portion 52 protrudes from the connecting portion 42a to the second opening portion 52a side. Thereby, the width | variety of the 1st opening part 51a and the 2nd opening part 52a can be made easier to expand by putting a finger | toe on the part which the side edge part 52b protruded. Therefore, the operation of removing the operating portion 24 can be simplified.

  In the drain plug device 10, the connecting portion 42 c extends from the side of the first main body 51 opposite to the first opening 51 a toward the pedestal 44 toward the opposite side of the first opening 51 a. As a result, when the operating unit 24 is inserted into the holding unit 40 from the side, a force is applied to the holding unit 40 so that the holding unit 40 approaches the pedestal 44 positioned on the opposite side of the first opening 51a. Even if it is made, it can suppress that the base part 44 deform | transforms. When the pedestal portion 44 is deformed, the relative position between the holding portion 40 and the pedestal portion 44 is shifted, and the plug lid 20 cannot be disposed at a desired position, and the water tightness between the plug lid 20 and the drain port 102a is lowered. There is a possibility that it will end. In the drain plug device 10, since the connecting portion 42 c extends to the pedestal portion 44 toward the opposite side to the first opening 51 a, the connecting portion 42 c is connected even if the above force acts on the holding portion 40 and the pedestal portion 44. The relative positional relationship between the holding portion 40 and the pedestal portion 44 can be maintained by the portion 42c. Accordingly, it is possible to suppress a decrease in watertightness between the plug lid 20 and the drain port 102a.

Fig.7 (a) and FIG.7 (b) are the perspective views and top views showing the modification of the attachment member which concerns on embodiment.
As shown in FIGS. 7A and 7B, the pedestal portion 44 of the attachment member 26 a further includes a slit portion 54. Note that components that are substantially the same in function and configuration as those in the above embodiment are given the same reference numerals, and detailed descriptions thereof are omitted.

  The slit portion 54 divides the second main body portion 52 in the circumferential direction. The pedestal 44 has a plurality of slits 54, for example. In this example, the pedestal portion 44 has two slit portions 54, slit portions 54a and 54b. The second opening 52a is provided between the plurality of connecting portions 42a and 42b. The slit portion 54a is provided between a plurality of connecting portions 42a and 42c different from the second opening 52a. Similarly, the slit portion 54b is provided between a plurality of connecting portions 42b and 42c different from the second opening 52a.

  Thus, in this example, the base part 44 is divided | segmented into three parts in the circumferential direction by the two slit parts 54a and 54b. The number of slit portions 54 is not limited to two and may be one. For example, when the number of connecting portions 42 is four or more, three or more slit portions 54 may be provided. One slit portion 54 is provided between two adjacent connecting portions 42. Further, as described above, the second opening 52 a is provided between the two connecting portions 42. Therefore, when the number of connecting portions 42 is M, the maximum number of slit portions 54 is M−1.

  In the attachment member 26a, by dividing the second main body 52 in the circumferential direction by the slit portion 54, the first opening 51a and the second opening 52a can be more easily spread. Therefore, the operation of assembling and removing the operating unit 24 can be simplified.

FIG. 8A and FIG. 8B are a perspective view and a front view showing a modification of the attachment member according to the embodiment.
As shown in FIGS. 8A and 8B, in the attachment member 26b, the first opening 51a is continuous from the lower end to the upper end of the first main body 51, and the first region R1 and the second region Region R2. 1st area | region R1 is a part which enables the action | operation part 24 to be horizontally inserted in the 1st main-body part 51 from the side. The second region R2 is located on the first region R1. The lateral width WA2 of the second region R2 is narrower than the lateral width WA1 of the first region R1. As a result, the second region R <b> 2 suppresses detachment of the operating unit 24 inserted into the first main body 51 from the first main body 51 in the upper part of the first main body 51.

  For example, the plug lid 20 may be removed after the drain plug device 10 is attached to the bathtub 100 and the pipe 200 in order to clean the drain plug portion 12 and the drain port portion 102. The stopper lid 20 is removed from the operating portion 24 by pulling upward from the drain port portion 102 and pulling it out from the support shaft 24 b of the operating portion 24. At this time, a user who is unfamiliar with the removal operation may apply a force in the horizontal direction to the plug lid 20 and the support shaft 24b.

  For this reason, for example, when the lateral width of the first opening 51a is a substantially constant width from the lower end to the upper end as in the attachment member 26 of the above embodiment, when removing the plug lid 20, There is a possibility that a force is applied in a direction in which the operating part 24 is detached from the first main body part 51, and an upper part of the operating part 24 is detached from the first main body part 51.

  In a state after the drain plug device 10 is attached to the bathtub 100 and the pipe 200, it is difficult to insert the operating portion 24 into the first main body portion 51 again, which causes an extra effort on the user or the like. Further, for example, if the stopper lid 20 is forcibly attached in a state where the upper portion of the operating portion 24 is removed from the first main body portion 51, the stopper lid 20 cannot be disposed at a desired position, and the stopper lid 20 and the drain outlet 102a There is a possibility that the water tightness is lowered.

  On the other hand, in the attachment member 26b, the first opening 51a has the first region R1 and the second region R2, and the lateral width WA2 of the second region R2 located on the first region R1 is It becomes narrower than the lateral width WA1 of one region R1, and prevents the operating part 24 inserted into the first main body part 51 from being removed from the first main body part 51.

  Thereby, in the attachment member 26b, after attaching the drain plug device 10 to the bathtub 100 and the pipe 200, for example, when removing the plug lid 20, a force is applied in a direction in which the operation unit 24 comes out of the first main body 51. Even so, it is possible to prevent the upper portion of the operating portion 24 from coming off from the first main body portion 51. For example, it is possible to suppress the trouble of inserting the operating part 24 into the first main body part 51 again, and to improve the usability of the drain plug device 10.

FIG. 9A and FIG. 9B are perspective views showing a modification of the attachment member according to the embodiment.
9A and 9B, in the attachment member 26c, the upper end of the first opening 51a is positioned below the upper end of the first main body 51. That is, in the attachment member 26 c, the first opening 51 a does not extend to the upper end of the first main body 51. The first main body 51 has a continuous portion 51d that is continuous with the portions on both sides of the first opening 51a of the first main body 51 above the first opening 51a. The continuous part 51d suppresses the operating part 24 inserted into the first main body part 51 from coming off from the first main body part 51.

  Thereby, also in the attachment member 26c, like the above attachment member 26b, after the drain plug device 10 was attached to the bathtub 100 and the pipe 200, a force was applied in a direction in which the operating portion 24 was removed from the first main body portion 51. Even so, it is possible to prevent the upper portion of the operating portion 24 from coming off from the first main body portion 51. Usability of the drain plug device 10 can be improved.

  The first main body 51 further has a recess 51e. The recess 51e is provided at a position different from the first opening 51a in the circumferential direction. The recess 51e is provided on the opposite side to the first opening 51a, for example. The recess 51 e is recessed downward from the upper end of the first main body 51. The recess 51e extends, for example, to the vicinity of the upper end of the case 24a of the operating unit 24. When the lower end of the recess 51e is positioned above the upper end of the case 24a, the distance between the lower end of the recess 51e and the upper end of the case 24a is, for example, 2 mm or less. For example, it is preferable that the lower end of the recess 51e extends to the same height as the upper end of the case 24a or below the upper end of the case 24a.

  Thereby, also when the continuous part 51d is provided, it can suppress that water accumulates in the upper part (space enclosed by the action | operation part 24 and the 1st main-body part 51) of the action | operation part 24. FIG. For example, it is possible to suppress the occurrence of dirt or the like in the upper part of the operating unit 24.

Fig.10 (a) and FIG.10 (b) are the perspective views and top views showing the modification of the attachment member which concerns on embodiment.
As illustrated in FIG. 10A and FIG. 10B, the attachment member 26 d includes a holding portion 40 and a plurality of support portions 46. The plurality of support portions 46 are integral with the holding portion 40, extend outward from the holding portion 40, and support the holding portion 40 on the drain port 102 a or the pipe 200.

  In this example, the attachment member 26d has three support portions 46a to 46c. A support portion 46 a that is one of the plurality of support portions 46 extends outward from one side end portion 51 b of the first main body portion 51. A support portion 46 b that is another one of the plurality of support portions 46 extends outward from the other side end portion 51 c of the first main body portion 51. Thereby, when inserting the action | operation part 24 into the 1st opening part 51a from a side, the action | operation part 24 can be guided to the 1st opening part 51a by the two support parts 46a and 46b. Thereby, the position adjustment with respect to the 1st opening part 51a of the action | operation part 24 can be made easy, and it can make it easy to insert the action | operation part 24 into the 1st opening part 51a from a side. Therefore, the assembling work can be simplified.

  Further, the support portion 46c extends outward from the side opposite to the first opening 51a of the first main body 51 toward the side opposite to the first opening 51a. Hereinafter, since the structure of the some support part 46 is substantially the same as the structure of the some connection part 42 of said each embodiment, detailed description is abbreviate | omitted.

  As described above, the holding unit 40 may be attached to the drain port 102 a or the pipe 200 by the plurality of support units 46 without providing the pedestal unit 44. In this attachment member 26d as well, the drain plug device 10 that can be easily assembled with a simple configuration can be provided as in the above embodiments.

  A protruding portion 48 extending in the circumferential direction is provided at an end portion of the support portion 46 opposite to the holding portion 40. Thereby, for example, the contact area with the inner peripheral surface of the drain port 102a or the pipe 200 can be increased, and the attachment member 26d can be attached to the drain port 102a or the pipe 200 more stably.

  In the attachment member 26d, for example, the downward movement in the pipe 200 is restricted by placing the protruding portion 48 of each support portion 46 on the placement portion 220. Moreover, in the attachment member 26d, each protrusion 48 is pressed downward by the drain port member 22, whereby the upward movement is restricted. Each protrusion 48 is stored in the first storage space 221 in the pipe 200, for example, and is sandwiched between the mounting portion 220 and the drain port member 22. In other words, the configuration of the protruding portion 48 is a configuration in which the length in the circumferential direction of the portion divided by the slit portion 54 of the pedestal portion 44 is shortened.

  In each said embodiment, the bathtub 100 is shown as a water tank to which the drain plug apparatus 10 is attached. The water tank is not limited to the bathtub 100, and may be, for example, a wash basin (a wash bowl) of a bathroom vanity.
