Description

  The present invention relates to a drain plug device provided corresponding to a flow path of drainage from a tank body.

  Conventionally, as a drain plug device provided in a tank body (for example, a bathtub or a basin), a pipe that constitutes a flow path of drainage that flows down from a drain port, a plug lid for opening and closing the drain port, and a plug lid A support shaft mechanism that is supported in a vertically movable state and a support shaft mechanism disposed in the pipe and a driving force due to displacement of a predetermined operation member (for example, an operation button or an operation handle) is transmitted to the support shaft. There is known a device including a transmission member capable of reciprocating movement (for example, see Patent Document 1). In such a drain plug device, the transmission member reciprocates with the displacement of the operation member, whereby the support shaft and the plug lid move up and down, and as a result, the drain port is opened and closed.

And a method in which the stopper lid is supported by a support member has been proposed (see, for example, Patent Document 2). In this method, the support member moves up and down as the drive member rotates as the transmission member moves. Thereby, the stopper lid supported by the support member also moves up and down, and the drain port is opened and closed. Moreover, the drive member is accommodated in the external cylinder part (attachment pipe) which protrudes outside from piping. The drive member housing space is watertight except for an opening (pipe side opening) located on one end side and opening toward the internal space of the pipe and an opening (end opening) located on the other end side. Yes.

  By the way, the sealing part for storing sealing water may be provided with respect to piping. In the case where such a sealing portion is provided, when the sealing surface of the sealing portion is configured to be positioned below the opening on the pipe side, the pipe is enlarged along the vertical direction. Is configured to be positioned above the opening on the pipe side, the sealing portion can be brought close to the drain port, and the pipe can be made compact along the vertical direction. In view of the space below the tank body, therefore, when it is desired to make the piping compact along the vertical direction, the sealing portion should be configured so that the sealing surface is located above the entire opening on the piping side. Can be considered.

  However, in this case, a large amount of sealed water may flow into the accommodation space from the pipe side opening and may accumulate in the accommodation space. Therefore, in order to prevent the sealing water from flowing out from the end opening, the end opening is closed, or a predetermined tube member or the like is connected in a watertight manner to the other end of the outer cylinder. It is possible.

  However, if the closed state of the end opening is released or the tube member is removed from the external cylinder for maintenance such as parts replacement, a large amount of sealed water flows out from the end opening. There is a fear. It is not preferable that a large amount of sealed water flows out in this way in view of workability and hygiene related to maintenance and the like. Also, in the unlikely event that a minute breakage that could lead to water leakage occurs in the sealing member or tube member for closing the end opening, a large amount of sealed water is likely to leak out from the end opening. It is also possible that

  The present invention has been made in view of the above circumstances, and the object thereof is to more reliably prevent the outflow of a large amount of sealed water while reducing the size of the piping, thereby improving workability and improving the workability. An object of the present invention is to provide a drain plug device capable of ensuring high hygiene.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

The pipe has a sealed water part in which sealed water is stored,
The sealing portion is configured such that its sealing surface is located above the entire piping side opening,
At least a part of the end opening is configured to be positioned above the sealing surface.

  In addition, the external cylinder part is “substantially incapable of relative displacement with respect to the piping”, for example, the external cylinder part, which is formed of, for example, a relatively hard or semi-rigid resin or metal and does not deform greatly. This means that the tube is not relatively easily deformable. Further, the term “sealed surface” refers to the surface of the sealed water when the maximum amount of sealed water is stored in the sealed portion.

  According to the said means 1, the sealing part is comprised so that its own sealing surface may be located above the whole piping side opening. Accordingly, the sealed water portion can be brought close to the drain port, and the piping can be made compact along the vertical direction. Thereby, the improvement of workability | operativity regarding the improvement of the installation freedom of an apparatus, attachment of piping, etc. can be aimed at. It is also possible to increase the degree of design freedom in the tank body.

  On the other hand, when the sealing surface is located above the entire piping side opening, there is a concern that a large amount of sealing water will flow out from the end opening. At least a part of is configured to be positioned above the sealing surface in the sealing portion. Therefore, it can prevent more reliably that a lot of sealing water flows out from an edge part opening. As a result, it is possible to improve workability related to maintenance and ensure good hygiene.

  Moreover, since the external cylinder part which comprises an accommodating part cannot be displaced relatively with respect to a tank body, an external cylinder part does not deform | transform easily and the position of an edge part opening does not go down. Thereby, the outflow prevention of sealed water and the improvement of workability | operativity and hygiene can be aimed at more reliably.

  Mean 2. The drain plug apparatus according to means 1, wherein the end opening is configured to be located above the sealing surface.

  According to the said means 2, the whole edge part opening is comprised so that it may be located above the sealing surface in a sealing part. Therefore, the outflow of the sealing water from the end opening can be extremely effectively suppressed, and the outflow of the sealing water from the end opening can be normally reduced to zero. As a result, operational effects such as improvement of workability and securing of good hygiene can be exhibited more remarkably.

Means 3. The transmission member accommodating portion is configured to extend obliquely upward from the driving member accommodating portion,

  In addition, as a structure which can arrange | position and remove a transmission drive member with respect to an accommodation space only through an edge part opening, for example, a drive member and a transmission member are previously integrated (for example, the connected state), and it passes through an edge part opening. A configuration in which the transmission drive member can be inserted into the housing portion and the transmission drive member can be pulled out from the housing portion through the end opening can be given. In addition, as a configuration that enables the transmission drive member to be disposed and removed from the accommodation space through the pipe side opening and the end opening, for example, in a state where the drive member and the transmission member are separated from each other, A configuration in which the drive member can be inserted and extracted and the transmission member can be inserted and extracted from the accommodating portion through the end opening can be given. In this configuration, when the driving member and the transmission member are arranged in the accommodation space, for example, the driving member and the transmission member are connected so that the driving force can be transmitted from the transmission member to the driving member. It may be configured.

  According to the means 3, the end opening is opened upward or obliquely upward. Then, it is possible to perform maintenance such as attachment of the transmission drive member and replacement of the transmission drive member only through the end opening or through the pipe side opening and the end opening. That is, according to the means 3, since the end opening is arranged at a relatively high position and faces upward, it is easy to dispose and remove the transmission drive member through the end opening from above the end opening. It can be carried out. Therefore, the transmission drive member can be easily attached and maintained, and good workability can be obtained.

  Furthermore, since the outer cylinder part which comprises an accommodating part cannot be displaced relatively with respect to a tank body, in arrangement | positioning etc. of the transmission drive member with respect to accommodation space, the site | part (transmission member accommodating part) in the edge part opening side in an accommodating part There is no need to specifically support. Thereby, workability | operativity can be improved further.

Therefore, smoother movement in the transmission member can be achieved, and operability can be improved. Furthermore, the breakage of the transmission member can be prevented more reliably, and the life of the apparatus can be extended.

  The configuration of the means 3 is particularly effective when the tank body is a bathtub. When a tank body is a bathtub, an accommodating part is normally arrange | positioned in a low position. Therefore, it becomes difficult to reach the end opening, and when carrying out maintenance such as attachment of the transmission drive member to the housing portion or replacement of the transmission drive member, a great burden is imposed on the operator. There is a risk that. However, by adopting the above means 3, the hand can easily reach the end opening, and the workability can be greatly improved. Further, when the tank body is a bathtub, it is difficult to secure a large space below the bathtub, and therefore the configuration of the means 1 and the like is particularly effective.

  The transmission drive member may be inseparable at a part other than the node part, or may be separable at a part other than the node part, as will be described later. However, in the case where separation is possible at a portion other than the node portion, the connecting force (force for separation) between those connected at the portion other than the node portion is determined by the drive member and the transmission member at the node portion. By making it larger than the coupling force, when the transmission member is pulled from the end opening side, the drive member and the transmission member are configured to be separated earlier than those coupled at a portion other than the node portion. The In addition, “the central axis of the transmission member accommodating portion” is not a strict central axis, but extends along the direction in which the transmission member accommodating portion extends and passes through the substantially center inside the transmission member accommodating portion. It can be called a line.

Therefore, it is possible to easily perform maintenance of a portion located on the side opposite to the drive member with respect to the intervening node portion of the transmission member.

  The means 5 is more easily maintained (replaced or the like) than the other parts of the transmission drive member for the part of the transmission member that is located on the opposite side of the drive member with respect to the intervening node. This is particularly effective in the case where a part (for example, an outer tube or a tube member that may be extended by being pulled unintentionally) is provided.

Thereby, the transmission of the driving force via the transmission member can be performed more reliably and more stably. As a result, good operability can be obtained.

  On the other hand, if the linear moving part that moves along the linear path and the connected part of the drive member that moves along the circular path are simply connected, a load is applied to the linear moving part due to the difference in the moving direction, It is conceivable that the smooth movement of the moving part is hindered.

  In this regard, according to the means 8, it is possible to prevent the load due to the difference in the moving direction of the linear moving portion and the connected portion from being applied to the linear moving portion by the adjusting mechanism portion. Thereby, a linear movement part can be moved smoothly and favorable operativity can be obtained more reliably.

Thereby, it is possible to prevent an excessively large force from being applied to each member (drive member and transmission member) of the transmission drive member and members (accommodating portions) located around the transmission drive member. As a result, damage and deformation of the member can be prevented more reliably.

  By the way, when a shock absorber is provided in the pipe, there is a concern that the parts disposed in the pipe will be increased by the presence of the shock absorber and the drainage performance will be reduced. In addition, foreign matters and dirt are likely to adhere to parts arranged in the pipe, and sanitary and cleanability may be reduced.

  The guide cylinder portion 5211B has a cylindrical small-diameter portion extending from the center of the root portion while the root portion is formed with a large diameter, and guides the movement of the absorber moving unit 5212 by the small-diameter portion. In addition, an inner wire 524 is inserted through the small diameter portion of the guide cylinder portion 5211B, and the inner wire 524 can protrude from the end of the small diameter portion. Furthermore, the base portion of the guide tube portion 5211B is formed with a hollow portion for accommodating a bowl-shaped flare portion provided at one end portion of the outer tube 523.

  The fixing lid portion 5211C is for attaching one end portion of the outer tube 523 to the case portion 5211. In the present embodiment, after the flare portion of the outer tube 523 is arranged in the hollow portion of the guide tube portion 5211B, the fixing lid portion 5211C is attached to the guide tube portion 5211B by, for example, screwing, and the fixing lid portion One end portion of the outer tube 523 is attached to the case portion 5211 by sandwiching the flare portion by 5211C and the guide tube portion 5211B.

  The absorber moving part 5212 is built in the transmission mechanism 521, and is arranged on the outer periphery of the small diameter part of the guide cylinder part 5211B. And it is movable along the path | route along the direction where the said small diameter part of the guide cylinder part 5211B is extended, ie, a linear path | route. That is, the absorber moving unit 5212 in the present embodiment corresponds to a linear moving unit.

  The absorber moving part 5212 includes an inner cylinder part 5212A, an outer cylinder part 5212B, and a shock absorber spring 5212C.

  The inner cylindrical portion 5212A has a cylindrical shape with one end (the end on the rod-shaped portion 522 side) closed, and the end of the inner wire 524 protruding from the guide cylindrical portion 5211B is in contact with the closed one end. It is possible. The inner cylinder part 5212A is pressed by the end of the inner wire 524, whereby the absorber moving part 5212 moves toward the drive member 51 along the extending direction of the small diameter part of the guide cylinder part 5211B. The other end of the inner cylinder portion 5212A is provided with a hook-like portion protruding outward to support (clamp) the shock absorber spring 5212C.

  The outer cylinder part 5212B accommodates the inner cylinder part 5212A inside, and has a cylindrical shape with one end closed like the inner cylinder part 5212A. In addition, a step portion for supporting (pinch) the shock absorber spring 5212C is provided on the inner periphery of the one end side portion of the outer cylinder portion 5212B. On the other hand, on the other end side of the outer cylindrical portion 5212B, a bulging portion protruding outward is provided for supporting (pinching) the return spring 5213.

  Further, a connecting shaft portion 521A having an oval cross section is provided at one end portion of the outer cylinder portion 5212B. The connecting shaft portion 521A functions as a connecting (connecting) portion to the rod-like portion 522.

  The shock absorber spring 5212 </ b> C is configured by a spring member that can be expanded and contracted along its longitudinal direction. The shock absorber spring 5212C is disposed between the outer periphery of the inner tube portion 5212A and the inner periphery of the outer tube portion 5212B, and is sandwiched between the flange portion of the inner tube portion 5212A and the step portion of the outer tube portion 5212B. It is in a compressed state. The shock absorber spring 5212 </ b> C has an elastic repulsion force that hardly compresses and deforms during normal reciprocation of the transmission member 52. On the other hand, when an overload is applied to the transmission member 52 along the reciprocating direction, the shock absorber spring 5212C is compressed and deformed to absorb the applied overload. That is, the absorber moving unit 5212 serves as both a shock absorber and a linear moving unit, and the linear moving unit is a component of the shock absorber (in this embodiment, a component constituting all of the shock absorber).

  Further, the entire absorber moving unit 5212 (particularly, the entire shock absorber spring 5212C having a load absorbing function) is configured to be positioned above the sealing surface 24 (see FIG. 5).

  The return spring 5213 is used for the backward movement of the transmission member 52 that has moved forward to the drive member 51 side. The return spring 5213 is disposed in a compressed state between an inwardly extending portion provided at one end of the housing main body 5211A and the bulging portion of the outer cylindrical portion 5212B.

  In the present embodiment, the transmission mechanism 521 has a thickness capable of passing through the inside of the guide member 61 and the joint member 62 and the tube member 4 which will be described later.

  Further, the transmission mechanism 521 has a transmission member accommodating portion 82 via a cover member 53 that holds itself inside at least one of the transmission member accommodating portion 82 and the tube member 4 (both in the present embodiment). (See FIG. 5).

  More specifically, the cover member 53 is formed of a predetermined resin, and has a relatively wide slit extending in the axial direction of the cover member 53 as shown in FIGS. . The slit can be widened along with the elastic deformation of the cover member 53, and is used when the transmission mechanism 521 is accommodated in the cover member 53. The cover member 53 holds the transmission mechanism 521 in a state in which the cover member 53 cannot reciprocate. The cover member 53 includes a flange-shaped portion 531 protruding from the outside, and the flange-shaped portion 531 has a shape including a plurality of convex portions and concave portions alternately along the circumferential direction of the cover member 53. ing. Then, along the reciprocating direction of the transmission member 52, the hook-shaped portion 531 is sandwiched between the attachment member 42 (end connection portion 42A) and the transmission member accommodating portion 82, so that the transmission mechanism 521. Is fixed to the transmission member accommodating portion 82 via the cover member 53.

  In the present embodiment, only the convex portion of the hook-shaped portion 531 is sandwiched between the mounting member 42 and the transmission member accommodating portion 82. Thereby, water flows from the inside of the tube member 4 (attachment member 42) to the inside of the transmission member accommodating portion 82 through the concave portion of the bowl-shaped portion 531.

  Returning to FIG. 7, the rod-like portion 522 is provided at one end of the transmission member 52 and is accommodated in the transmission member accommodation portion 82. The rod-shaped part 522 is formed of a predetermined resin. Further, in the cross section orthogonal to the longitudinal direction of the rod-shaped portion 522, at least a part (in this embodiment, a sandwiching connection portion 522B described later) has a non-circular cross-section (for example, a cross-sectional rectangular shape, a cross-sectional elliptical shape, a cross-sectional length). It has a circular shape.

  As described above, at least a part of the inner side surface of the transmission member accommodating portion 82 is close to the outer surface of the rod-shaped portion 522 and has a non-circular cross-section that follows the cross-sectional shape of the rod-shaped portion 522. Reference numeral 522 denotes a state in which relative rotation with respect to the transmission member accommodating portion 82 is restricted. That is, in this embodiment, the rotation regulating means 14 that regulates the relative rotation of the rod-shaped portion 522 with respect to the transmission member accommodating portion 82 is configured by the outer surface of the rod-shaped portion 522 and the inner surface of the transmission member accommodating portion 82 ( (See FIG. 5).

  In addition, sandwiching connecting portions 522A and 522B having bifurcated arm portions are provided at both ends of the rod-like portion 522. And the drive member 51 and the transmission member 52 are connected in the accommodating space 8A by arranging the connected portion 513 between both arm portions of the sandwiching connection portion 522A provided at one end of the rod-like portion 522. It has become a state. In the present embodiment, a node portion 15A for connecting the drive member 51 and the transmission member 52 is configured by the connected portion 513 and the sandwiching connection portion 522A.

  In the state where the drive member 51 and the transmission member 52 are coupled, the disk portion provided at the tip of the connected portion 513 and the support protrusion 514 is directed toward the internal space side of the pipe 2. The connected portion 513 is prevented from coming off from the transmission member 52, and the drive member 51 is held at a fixed position along the direction of the rotation axis CL1.

  In addition, the gap between the both arm portions of the sandwiched connecting portion 522A is usually smaller than the outer diameter of the connected portion 513 (the width of the connected portion 513 when viewed from the side). However, since the rod-shaped portion 522 is made of resin, the gap can be made larger than the outer diameter of the connected portion 513 by elastically deforming both arm portions. In the present embodiment, the drive member 51 and the transmission are transmitted by pushing the rod-like portion 522 toward the connected portion 513 side in a state where the portion forming the gap of the sandwiched connecting portion 522A is in contact with the connected portion 513. The member 52 can be connected. On the other hand, the transmission member 52 (rod-like part 522) can be separated from the drive member 51 by the node part 15A by applying a force in the direction of separating the stick-like part 522 from the connected part 513.

  Furthermore, the connecting shaft portion 521A is disposed between the arm portions of the sandwiching connecting portion 522B provided at the other end of the rod-shaped portion 522, so that the rod-shaped portion 522 and the transmission mechanism 521 are accommodated in the accommodating space 8A. It is in a connected state. In the present embodiment, the connecting shaft portion 521A and the sandwiching connecting portion 522B constitute the interposition node portion 15B for connecting the rod-like portion 522 and the transmission mechanism 521, that is, for connecting the components of the transmission member 52 to each other. ing.

  Note that the gap between both arm portions of the sandwiched connecting portion 522B is normally smaller than the outer diameter of the connecting shaft portion 521A (the width of the connecting shaft portion 521A when viewed from the side). By elastically deforming 522B, the bar-like portion 522 and the transmission mechanism 521 can be connected and separated by the intervening node portion 15B.

  However, in this embodiment, by adjusting the outer diameters of the connected portion 513 and the connecting shaft portion 521A, the connecting force of the holding connecting portion 522A and the connected portion 513 (force for separating both) is held. The connecting force is smaller than that of the connecting portion 522B and the connecting shaft portion 521A. Therefore, when the transmission mechanism 521 is pulled in a direction away from the drive member 51 in a state where the drive member 51, the rod-shaped portion 522, and the transmission mechanism 521 are connected, the drive member is separated before the transmission mechanism 521 and the rod-shaped portion 522 are separated. 51 and the rod-shaped part 522 (transmission member 52) are separated.

  Further, the rod-shaped portion 522 is rotatable at a connecting portion (connecting portion) with the connected portion 513 with respect to the connected portion 513 on a rotating shaft parallel to the rotating shaft CL1. Further, the rod-like portion 522 is rotatable on a rotation axis parallel to the rotation axis CL1 with respect to the absorber movement portion 5212 at a connection portion (connection portion) with the absorber movement portion 5212. When the transmission member 52 moves, the rod-shaped portion 522 rotates at the connecting portion of the absorber moving portion 5212 and the connected portion 513, so that the moving direction of the absorber moving portion 5212 and the moving direction of the connected portion 513 are changed. It is possible to prevent a load due to the difference from being applied to the absorber moving unit 5212. In the present embodiment, the adjustment mechanism portion 16 is configured by the rod-shaped portion 522.

  The outer tube 523 is formed of a predetermined resin, rubber, or the like and has a long cylindrical shape. As described above, one end portion of the outer tube 523 is attached to the transmission mechanism 521 (case portion 5211), and the other end portion of the outer tube 523 is attached to the operation side mechanism portion 63 described later.

  The inner wire 524 has flexibility and is inserted into the outer tube 523 so as to be reciprocally movable. As the inner wire 524, for example, a core coil in which a flexible metal wire is spirally wound, a rod (bar-shaped member) formed of a flexible resin, and a plurality of metal wires are used. Lines can be used.

  Further, in the present embodiment, the transmission member 52 can be disposed in the transmission member accommodating portion 82 through the end opening 8C and can be detached from the transmission member accommodating portion 82 in a state separated from the driving member 51. ing. Therefore, as described above, since the drive member 51 can be arranged / removed from the drive member accommodating portion 81 through the pipe side opening 8B, the transmission drive member 5 in the present embodiment includes the end opening 8C and the pipe. It can be arranged in the accommodation space 8A through the side opening 8B and can be removed from the accommodation space 8A.

  Further, in a state in which the tube member 4 is removed from the transmission member accommodating portion 82, the transmission member 52 can be pulled from the end opening 8C side, and the transmission member 52 is pulled to be driven by the node portion 15A. The transmission member 52 can be separated from the member 51.

  On the other hand, in a state where the drive member 51 is disposed in the drive member accommodating portion 81, the transmission member 52 disposed in the transmission member accommodating portion 82 is pushed into the drive member 51 side, so that the node 15A in the accommodating space 8A The drive member 51 and the transmission member 52 can be connected.

  Returning to FIG. 2, the operating device 6 includes a cylindrical guide member 61 inserted into the mounting hole 105, a cylindrical joint member 62 screwed onto the outer periphery of the guide member 61, and the guide member 61. An operating-side mechanism 63 held by this is provided.

  The guide member 61 and the joint member 62 are screwed into a female screw provided on the inner periphery of the joint member 62 by screwing a male screw provided on the outer periphery of the guide member 61, and a hook shape provided on the end of the guide member 61. The flange portion 104 is sandwiched between the portion and the upper end portion of the joint member 62 so as to be attached to the bathtub 100. A seal member 65 formed of an elastically deformable material is disposed between the back surface of the flange portion 104 and the upper end surface of the joint member 62, thereby preventing water leakage between the flange portion 104 and the joint member 62. It has been.

  Further, the other end of the tube member 4 is connected to the end of the joint member 62 in a watertight manner. In the present embodiment, the internal space formed by the joint member 62, the tube member 4, and the housing portion 8 from the joint member 62 to the pipe side opening 8B is watertight. Thereby, when water infiltrates into the joint member 62, the water is guided to the internal space (drainage flow path) of the pipe 2 through the tube member 4 and the accommodating portion 8, and the pipe side opening 8B. It is designed not to leak from any other.

  The operation side mechanism unit 63 includes an operation member 64 that can be displaced relative to the bathtub 100 and a lock mechanism (not shown). The operation member 64 is located above the end opening 8C and includes an operation button 641 and a shaft portion 642.

  The operation button 641 has a disk shape and is disposed on the inner periphery of the guide member 61. The shaft portion 642 extends along the axial direction of the guide member 61 and can reciprocate along the axial direction. An operation button 641 is attached to the upper end portion of the shaft portion 642.

  Further, the lower end portion of the shaft portion 642 can contact the other end portion of the inner wire 524. Then, when the shaft portion 642 moves forward (downward) with the pressing of the operation button 641, that is, when the operation member 64 is displaced downward, the inner wire 524 pressed by the shaft portion 642 is moved to the outer side. The tube 523 moves forward (moves from the operating device 6 to the drive member 51 side). As a result, the absorber moving part 5212 pressed against one end of the inner wire 524 moves forward, and consequently the rod-shaped part 522 moves forward. As a result, the drive member 51 rotates to one side and the support member 512 is raised.

  Here, when the pressing of the operation button 641 is released in a state where the shaft portion 642 is moved downward from a predetermined position by pressing of the operation button 641, the shaft portion 642 is moved to a predetermined lower position by the lock mechanism. The inner wire 524 is held in a state of being locked and eventually moved forward. Thereby, the members (the inner wire 524, the absorber moving part 5212, the rod-like part 522, and the drive member 51) that move forward due to the displacement of the operation member 64 in the transmission drive member 5 are maintained in the state after the forward movement.

  On the other hand, when the operation button 641 is pressed in a state where the shaft portion 642 is locked at the lower position, the lock of the shaft portion 642 by the lock mechanism is released, and the inner wire 524 is pulled by the repulsive force from the return spring 5213. While returning in the outer tube 523, the axial part 642 moves up to the original position. Further, the reversing force from the return spring 5213 causes the absorber moving portion 5212 and the rod-like portion 522 to move backward, whereby the drive member 51 rotates to the other side and the support member 512 is lowered.

  Returning to FIG. 1, the plug lid unit 7 includes a water passage member 71, a support shaft 72, and a plug lid 73. The stopper lid unit 7 can be installed in the pipe 2 from above the pipe 2 and can be removed from the pipe 2. Specifically, the stopper cover unit 7 can be disposed in the pipe 2 by introducing the stopper cover unit 7 into the pipe 2 from above the pipe 2. On the other hand, by pulling up the plug cover unit 7 from above the pipe 2, the plug cover unit 7 can be removed from the pipe 2.

  The water passing member 71 is a member that is lifted by the support member 512 at least when the support member 512 moves up. The water passage member 71 has an annular shape and is disposed along the inner peripheral surface of the pipe 2 (inflow portion 221). Further, the water passing member 71 is attached to the lower end portion of the support shaft 72 via an arm portion extending along the radial direction.

  The support shaft 72 is disposed substantially at the center of the pipe 2 and has a rod shape extending in the vertical direction. Further, the upper end of the support shaft 72 is attached to the center of the back surface of the plug lid 73, thereby supporting the plug lid 73.

  The plug lid 73 includes a disk-shaped plug lid main body portion 731 made of resin or the like, and a packing portion 732 attached to the plug lid main body portion 731. The packing portion 732 is formed in an annular shape from an elastically deformable material (for example, rubber or resin), and is attached to the outer peripheral side of the back surface of the plug lid main body portion 731. In this embodiment, the plug lid 73 is indirectly supported by the support member 512 via the water passage member 71 and the support shaft 72. However, the plug lid is directly supported by the support member. It is good.

  In the drain plug device 1 configured as described above, the transmission member 52 (the inner wire 524, the absorber moving portion 5212, and the rod-shaped portion 522) moves forward with the displacement of the operation member 64, and the drive member 51 moves to one side. By rotating, the support member 512 moves up, and the plug lid 73 (plug lid unit 7) moves up. As a result, the packing part 732 is separated from the drain port member 21 so that the drain port 103 is opened.

  If a downward force is applied to the plug lid 73 with the stopper lid 73 moved upward, such as when the stopper lid 73 is stepped on while the stopper lid 73 is moved upward, the drive member 51 or the like is moved. Thus, an overload along the reciprocating direction of the transmission member 52 can be applied. However, even when an overload is applied, the absorber moving unit 5212 can absorb the load.

  On the other hand, when the lock by the lock mechanism is released along with the displacement of the operation member 64, the transmission member 52 is moved backward, and the drive member 51 is rotated to the other side, so that the support member 512 is moved downward, and the plug The lid 73 (plug lid unit 7) moves downward. As a result, the entire outer peripheral portion of the packing portion 732 comes into contact with the drain port member 21 so that the drain port 103 is closed. That is, the driving force due to the displacement of the operation member 64 is transmitted to the driving member 51 through the transmission member 52, and the driving member 51 rotates and the support member 512 moves up and down, whereby the plug lid 73 moves up and down.

  In the present embodiment, when the drainage port 103 is in the open state, the water passing member 71 is placed on the support member 512, while the support member 512 is disposed at the lowest position (drainage When the mouth 103 is in the closed state), the water passing member 71 is separated from the support member 512 (floating state). As a result, when the drainage port 103 is closed, the packing portion 732 can be more reliably brought into contact with the drainage port member 21, and good watertightness can be obtained.

  Next, a method for attaching the drain plug device 1 described above will be described. First, the drain port member 21 is screwed into the drain pipe 22 so that the pipe 2 is connected to the bottom wall portion 101 of the bathtub 100. The pipe 2 is in a state where the external cylinder portion 3 is connected in advance.

  Further, the guide member 61 and the joint member 62 are attached to the bathtub 100 by screwing the guide member 61 to the joint member 62. Next, the other end of the tube member 4 is connected to the end of the joint member 62.

  Thereafter, the transmission member 52 separated from the drive member 51 is sent from the operation device 6 side to one end side of the tube member 4 through the guide member 61, the joint member 62, and the inside of the tube member 4. The transmission member 52 includes a transmission mechanism 521, a rod-shaped portion 522, an outer tube 523, and an inner wire 524, and the other end of the outer tube 523 is connected in advance to the operation side mechanism portion 63. It is a thing. Then, the transmission mechanism 521 is disposed inside the cover member 53 with the transmission mechanism 521 extended from one end of the tube member 4. The rod-like portion 522 may be connected to the transmission mechanism 521 after the transmission mechanism 521 is taken out from one end of the tube member 4.

  Separately from the transmission member 52, the drive member 51 separated from the transmission member 52 is disposed in the drive member accommodating portion 81 through the pipe side opening 8 </ b> B. The drive member 51 may be disposed in the drive member accommodating portion 81 as long as the pipe 2 is connected to the bottom wall portion 101.

  Next, the transmission member 52 is inserted from the end opening 8 </ b> C into the transmission member accommodating portion 82 with the rod-shaped portion 522 at the top. Then, by pushing the transmission member 52 toward the drive member 51 side, the connected portion 513 is disposed between the arm portions of the sandwiching connection portion 522A, and the drive member 51 and the transmission member 52 are connected.

  Next, the nut member 42B is rotated so that the male screw portion 8D provided in the transmission member accommodating portion 82 is screwed into the nut portion 42B, whereby the member 42 for attaching the tube member 4 to the transmission member accommodating portion 82 is obtained. At the same time, the attachment member 42 and the transmission member accommodating portion 82 sandwich the flange-shaped portion 531 of the cover member 53. Accordingly, the tube member 4 is connected to the transmission member accommodating portion 82, and the transmission mechanism 521 covers the inside of at least one of the transmission member accommodating portion 82 and the tube member 4 (both in the present embodiment). The state is fixed to the transmission member accommodating portion 82 via the member 53.

  Then, the operation side mechanism 63 is held by the guide member 61 and the operation button 641 is attached to the shaft 642. Further, the stopper cover unit 7 is arranged from above the pipe 2 into the pipe 2. Thereby, installation of the drain plug apparatus 1 with respect to the bathtub 100 is completed. Note that the operation-side mechanism 63 is held by the guide member 61 and the operation button 641 is attached to the shaft 642 after the transmission member 52 is sent to one end side of the tube member 4 through the tube member 4 or the like. You can go anytime.

  In addition, the drain plug apparatus 1 can be removed from the bathtub 100 by following the procedure reverse to the attachment method. Therefore, when the transmission drive member 5 is removed from the accommodating portion 8 in order to perform maintenance such as replacement of the transmission drive member 5, the transmission member 52 is pulled from the end opening 8C side so as to be clamped and connected from the connected portion 513. The part 522A can be removed, and the drive member 51 and the transmission member 52 can be separated. By separating the drive member 51 and the transmission member 52, the drive member 51 can be removed from the drive member accommodating portion 81 through the pipe side opening 8B, and the transmission member 52 can be removed from the transmission member accommodating portion 82 through the end portion opening 8C. Can be removed.

  In addition, since the whole piping side opening 8B is located below the sealing surface 24, the drive member 51 arrange | positioned at the drive member accommodating part 81 is the state normally used for sealing water. Therefore, the removed drive member 51 floats upward of the pipe 2 by sealing water.

  As described above in detail, according to the present embodiment, the sealing portion 23 is configured such that its sealing surface 24 is located above the entire piping-side opening 8B. Therefore, the sealing part 23 can be brought close to the drainage port 103, and the pipe 2 can be made compact along the vertical direction. Thereby, the improvement of workability | operativity which concerns on the improvement of the installation freedom degree of apparatus, attachment of piping 2, etc. can be aimed at. It is also possible to increase the degree of design freedom in the bathtub 100.

  On the other hand, when the sealing surface 24 is located above the entire piping-side opening 8B, there is a concern that a large amount of sealing water will flow out from the end opening 8C. On the other hand, in the present embodiment, at least a part of the end opening 8 </ b> C is configured to be positioned above the sealing surface 24. Accordingly, it is possible to more reliably prevent a large amount of sealed water from flowing out from the end opening 8C. As a result, it is possible to improve workability related to maintenance and ensure good hygiene.

  Moreover, since the external cylinder part 3 which comprises the accommodating part 8 cannot be displaced relatively with respect to the bathtub 100, the external cylinder part 3 does not deform | transform easily and the position of the edge part opening 8C falls. Thereby, while being able to aim at prevention of the sealing water outflow more reliably, workability | operativity and hygiene can be improved more.

  In particular, in the present embodiment, since the entire end opening 8C is configured to be located above the sealing surface 24, the outflow of the sealing water from the end opening 8C can be extremely effectively suppressed. The outflow of the sealing water from the end opening 8C can be normally zero. As a result, operational effects such as improvement of workability and securing of good hygiene can be exhibited more remarkably.

  Moreover, since the attachment target of the drain plug device 1 is the bathtub 100, it is usually difficult to reach the storage unit 8 and it is considered difficult to arrange and remove the transmission drive member 5 from the storage unit 8. In the present embodiment, the transmission member accommodating portion 82 extends obliquely upward, and the end opening 8C opens obliquely upward. Accordingly, since the end opening 8C is disposed at a relatively high position and faces upward, the transmission drive member 5 can be easily disposed and removed from the upper end opening 8C through the end opening 8C. it can. Therefore, maintenance such as attachment and replacement of the transmission drive member 5 can be easily performed, and good workability can be obtained.

  In addition, since the outer cylindrical portion 3 is substantially incapable of relative displacement with respect to the bathtub 100, when the transmission drive member 5 is disposed in the accommodation space 8A, the portion on the end opening side of the accommodation portion 8 (transmission member accommodation portion 82). There is no need to specifically support. Thereby, workability | operativity can be improved further.

  Furthermore, since the end opening 8C is obliquely upward, the transmission member 52 can be guided from the operation member 64 side into the accommodating portion 8 without being bent excessively. Therefore, smoother reciprocation of the transmission member 52 can be achieved, and operability can be improved. Furthermore, the transmission member 52 can be more reliably prevented from being damaged, and the life of the apparatus can be extended.

  In addition, the drive member 51 and the transmission member 52 can be connected in the accommodation space 8A by pushing the transmission member 52 toward the drive member 51 side. Therefore, the transmission drive member 5 can be more easily attached and maintained, and workability can be further improved.

  In addition, when removing the transmission drive member 5 from the accommodating portion 8, the transmission member 52 and the drive member 51 can be separated at the node portion 15A by pulling the transmission member 52 from the end opening 8C side. Therefore, the transmission member 52 and the drive member 51 connected in the accommodation space 8A can be separated very easily, and the transmission member 52 can be removed from the transmission member accommodation portion 82 through the end opening 8C, or the drive member 51 can be removed. It can be easily removed from the drive member accommodating portion 81 through the pipe side opening 8B. As a result, maintenance and the like can be performed more easily, and better workability can be obtained.

  In addition, the transmission member accommodating portion 82 extends obliquely upward from the driving member accommodating portion 81, and when viewed in plan, the rotation axis CL1 of the driving member 51 and its own central axis CL2 are from the internal space of the pipe 2. Is also configured to be orthogonal to the outside. Therefore, it is possible to prevent the transmission member accommodating portion 82 from protruding excessively from the pipe 2 while sufficiently extending the transmission member accommodating portion 82 upward. Thereby, size reduction of the space required in order to arrange | position the accommodating part 8 can be achieved, and the installation freedom degree of an apparatus can be raised more combined with the piping 2 being compact. Further, the convenience related to the handling of the apparatus can be further enhanced, and the workability related to the installation (installation) and maintenance of the apparatus can be further improved.

  Furthermore, since the drive member 51 is configured to float on water, the drive member 51 can be lifted to the upper side of the pipe 2 by sealing water after the drive member 51 is removed. Thereby, it is possible to easily pull out the driving member 51 from the pipe 2. As a result, the workability related to the removal of the drive member 51 can be remarkably enhanced.

  In addition, the transmission member 52 includes an absorber moving unit 5212 that moves along a linear path. Therefore, when the transmission member 52 reciprocates, the transmission member 52 can be more reliably prevented from shaking. Thereby, transmission of the driving force through the transmission member 52 can be performed more reliably and more stably. As a result, good operability can be obtained.

  On the other hand, the adjustment mechanism unit 16 can prevent a load due to a difference in the moving direction of the absorber moving unit 5212 and the connected portion 513 from being applied to the absorber moving unit 5212. Thereby, the absorber moving part 5212 can be moved smoothly, and favorable operativity can be obtained more reliably.

  Further, the load applied to the transmission drive member 5 can be absorbed by the absorber moving part 5212. Thereby, it is possible to prevent an excessively large force from being applied to each member (the drive member 51 and the transmission member 52) of the transmission drive member 5 and the member (the accommodating portion 8) positioned around the transmission drive member 5. As a result, damage and deformation of the member can be prevented more reliably.

  Furthermore, the absorber moving part 5212 is arranged not on the inside of the pipe 2 but on the outside of the pipe 2. Therefore, good drainage performance, hygiene, and the like in the pipe 2 can be realized. Furthermore, the absorber moving unit 5212 is disposed outside the pipe, so that the absorber moving unit 5212 can be easily replaced or maintained.

  In addition, since the entire absorber moving part 5212 is disposed above the sealing surface 24, the absorber moving part 5212 can be more reliably prevented from getting stuck. Thereby, the corrosion and deterioration of the absorber moving part 5212 can be effectively suppressed, and the life of the apparatus can be further extended.

  Further, the absorber moving unit 5212 also serves as a linear moving unit and a shock absorber. In other words, the linear moving unit also serves as a shock absorber component. Therefore, the transmission member 52 can be made compact. Moreover, compared with the case where a shock absorber and a linear moving part are provided separately, manufacturing cost can be reduced.

  In addition, since the absorber moving part 5212 is built in the transmission mechanism 521, the transmission member 52 can be further downsized.

  Further, the rotation restricting means 14 can restrict the relative rotation of the rod-like portion 522 with respect to the transmission member accommodating portion 82. Therefore, the driving force due to the displacement of the operation member 64 can be transmitted to the driving member 51 without loss. As a result, operability can be further improved.

  Furthermore, according to the present embodiment, by attaching the tube member 4 to the transmission member accommodating portion 82, as a result, not only the connection between both, but also the attachment of the transmission mechanism 521 and the outer to the transmission member accommodating portion 82 are achieved. Indirect attachment of the tube 523 can also be performed. Therefore, workability related to attachment and maintenance can be further improved.

  In addition, the hook-shaped portion 531 is sandwiched between the transmission member accommodating portion 82 and the mounting member 42 along the reciprocating direction of the transmission member 52, so that the transmission mechanism held by the cover member 53 and the cover member 53 is secured. 521 can be more reliably arranged at a fixed position along the reciprocating direction. Accordingly, the relative positional relationship between the members (rod-like portion 522 and drive member 51) located on the drive member 51 side and the transmission mechanism 521 can be made appropriate without specially adjusting the position of the transmission mechanism 521. it can. Thereby, workability | operativity can be improved further.

  Further, since the internal space from the joint member 62 to the pipe side opening 8B is configured to be watertight, the water that has entered the joint member 62 is allowed to enter the inside of the pipe 2 (that is, through the tube member 4 and the accommodating portion 8). , It is possible to guide more reliably to the drainage channel side). Thereby, it can prevent that the water which infiltrated into the coupling member 62 flows out into the location which is not a flow path of a waste_water | drain, and can improve sanitaryness etc. more.

  Furthermore, since the recessed part of the bowl-shaped part 531 functions as a water flow path, the water which has flowed through the tube member 4 from the joint member 62 side can be flowed more smoothly to the pipe 2 side (drainage flow path side). . In addition, foreign matters such as hair and dust that have entered from the joint member 62 can be captured by the plurality of convex portions constituting the hook-shaped portion 531. As a result, it is possible to more reliably suppress the entry of foreign matter into the drive member 51 side, and to improve the operational stability.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the transmission drive member 5 is configured to be disposed in the accommodation space 8A and removable from the accommodation space 8A through the end opening 8C and the piping side opening 8B. On the other hand, the transmission drive member may be arranged in the accommodation space through only the end opening and detachable from the accommodation space.

  For example, as shown in FIG. 11, the transmission member accommodating portion 182 extends from the driving member accommodating portion 181 extending in the horizontal direction obliquely upward, while the center axis and transmission of the driving member accommodating portion 181 when viewed in plan view. The housing portion 18 is configured so that the central axis of the member housing portion 182 is coaxial. Note that at least a part of the end opening 18 </ b> C (in this example, most of the end opening 18 </ b> C) of the housing portion 18 is configured to be positioned above the sealing surface 24. On the other hand, the piping side opening 18 </ b> B of the accommodating portion 18 is configured so that the entirety thereof is located below the sealing surface 24.

  Further, the transmission drive member 17 is assumed to be connected to a drive member 171 having a support member 171A and a rotatable transmission member 172 so that the transmission drive member 17 can be bent at a connection portion between the drive member 171 and the transmission member 172. Configure. A connection portion between the drive member 171 and the transmission member 172 is disposed corresponding to a bent portion of the accommodating portion 18. The drive member 171 and the transmission member 172 are sized to be inserted from the end opening 18C. The transmission member 172 rotates as the inner wire 524 reciprocates.

  With the configuration as described above, as shown in FIG. 12, the transmission drive member 17 is inserted into the housing portion 18 through the end opening 18C with the drive member 171 at the head, thereby It can be arranged in the accommodating space 18A of the accommodating part 18 through only the part opening 18C. Further, by pulling out the transmission drive member 17 from the accommodating portion 18 through the end opening 18C, the transmission drive member 17 can be removed from the accommodation space 18A through only the end opening 18C.

  (B) In the above embodiment, the drain pipe 22 is configured such that the folded portion 222 extends obliquely upward from the lower end of the inflow section 221, but the configuration of the drain pipe is not limited to this. Therefore, for example, as shown in FIG. 13, the orthogonal part 224 extends in the horizontal direction from the lower end of the inflow part 221, and the orthogonal part 224 is connected to a trap (not shown) provided at the drainage port of the washing place ( (Integrated). In this case, the sealing water may be accumulated up to the sealing surface 28 of the sealing portion 27 constituted by the trap, the orthogonal portion 224 and the inflow portion 221.

  (C) As shown in FIG. 14, the end opening 20 </ b> C is positioned on the side of the peripheral wall 102 by adopting a configuration in which the transmission member accommodating portion 20 (external cylinder portion 31) is further extended upward. You may comprise. In this case, the hand is very easily reachable with respect to the end opening 20C, and the transmission drive member 19 can be more easily placed and removed from the accommodation space 20A through the end opening 20C. As a result, maintenance and the like can be performed more easily, and workability can be further improved.

  Further, the extending angle of the transmission member accommodating portion 20 positioned on the communication hole 221A side and the extending angle of the transmitting member accommodating portion 20 positioned on the end opening 20C side (the horizontal plane and the central axis of the transmitting member accommodating portion 20). The angle of the transmission member accommodating portion 20 located on the communication hole 221A side is smaller than the angle of the transmission member accommodating portion 20 located on the end opening 20C side. You may comprise as follows. In this case, the transmission is performed so that the angle is relatively gentle at a position in the vicinity of the communication hole 221A and the angle is relatively steep at a position away from the communication hole 221A and hardly interferes with the bottom wall 101. The member accommodating part 20 can be comprised. Therefore, the drive member accommodating portion 81 located on the base side of the transmission member accommodating portion 20 can be disposed on the upper side (close to the drainage port), and the drive member 51 and the communication hole 221A can be disposed on the upper side. It becomes possible. Thereby, the compactization along the up-down direction of the piping 2 can be achieved further.

  Further, the transmission member accommodating portion 20 may have a shape extending along the peripheral wall portion 102. In this case, the transmission member accommodating portion 20 can be arranged in a well-organized state with respect to the bathtub 100. As a result, the apparatus can be made more compact.

  In the example shown in FIG. 14, the transmission drive member 19 has a plurality of rod-shaped portions 191 connected in series so as to be capable of rotating relative to each other in order to correspond to the lengthening of the transmission member housing portion 20. , 192, 193. The rod-shaped portion 193 is a member that moves along a linear path together with the absorber moving portion 5212, that is, a linear moving portion. In addition, the bar-shaped portions 191 and 192 constitute an adjustment mechanism unit that prevents the load due to the difference between the moving direction of the bar-shaped portion 193 and the moving direction of the connected portion 513 from being applied to the bar-shaped portion 193.

  (D) Although not specifically described in the above embodiment, as shown in FIG. 15, a water passage portion 511 </ b> A serving as a water flow path may be formed through the cylindrical portion 511 of the drive member 51. In this case, water can be smoothly flowed in the accommodating portion 8, and the water passing ability in the accommodating portion 8 can be sufficiently ensured. As a result, it is possible to appropriately (faster) discharge water flowing from the operation member 64 side to the pipe 2 side.

  From the viewpoint of smoother water flow, it is preferable that the area of the water passage portion 511 </ b> A is larger than the area of the gap between the outer periphery of the drive member 51 (columnar portion 511) and the drive member housing portion 81. Moreover, even if it is a case where the position along the rotation direction of the drive member 51 changes by forming the water flow part 511A so that the center of the drive member 51 (columnar part 511) may be penetrated, it is water flow. The position of the portion 511A hardly changes, and smoother water flow can be achieved.

  (E) The adjustment mechanism unit is not limited as long as it can prevent the load due to the difference between the moving direction of the linear moving unit and the moving direction of the connected portion from being applied to the linear moving unit. It is not limited to. Therefore, for example, as shown in FIG. 16, a protrusion-like connected portion 513 and a hole-like or hollow-like protrusion arranging portion 5216A formed at one end portion of the linear moving portion 5216 and the connected portion 513 are arranged. The adjustment mechanism unit 32 may be configured as described above. The protrusion placement portion 5216A has such a size that the connected portion 513 can sufficiently move in the direction intersecting the moving direction of the linear moving portion 5216. Of course, the adjustment mechanism portion may be configured by providing a protrusion on the linear moving portion and using a hole-like or depression-like protrusion arrangement portion on which the protrusion is arranged as the connected portion.

  (F) In the above embodiment, when the transmission member 52 is pulled from the end opening 8C side, the drive member 51 and the transmission member 52 are separated at the node portion 15A. On the other hand, the transmission mechanism 521 is moved away from the drive member 51 by making the coupling force of the sandwiched coupling part 522A and the connected part 513 larger than the coupling force of the sandwiching coupling part 522B and the coupling shaft part 521A. When pulled, the transmission mechanism 521 and the rod-shaped portion 522 may be separated at the interposition node 15B before the drive member 51 and the rod-shaped portion 522 (the transmission member 52) are separated. That is, when the transmission member 52 is pulled from the end opening 8C side, the components of the transmission member 52 may be separated from each other at the interposition node 15B. In this case, it is possible to easily perform maintenance on a portion of the transmission member 52 that is located on the opposite side of the drive member 51 with respect to the interposed node 15B. In particular, in the above embodiment, a transmission mechanism 521 having the absorber moving portion 5212 is provided for a portion of the transmission member 52 that is located on the opposite side of the drive member 51 with respect to the interposed node 15B. Maintenance of the mechanism 521 can be easily performed.

  (G) In the above-described embodiment, the accommodating portion 8 is configured by a portion that forms the communication hole 221 </ b> A in the outer cylindrical portion 3 and the pipe 2, but the accommodating portion 8 includes at least the outer cylindrical portion 3. I just need it. Therefore, for example, a portion of the outer cylinder portion 3 that is located on the pipe 2 side is inserted into the communication hole 221 </ b> A so that a portion that forms the communication hole 221 </ b> A in the pipe 2 does not become a constituent portion of the housing portion 8. Good. In this case, the accommodating portion 8 includes only the outer cylinder portion 3. In this case, the pipe side opening 8 </ b> B is formed by an opening that opens toward the inner space side of the pipe 2 in the outer cylinder portion 3. In this case, the communication hole 221A and a part of the internal space of the outer cylindrical portion 3 are overlapped, but the point that the accommodating space 8A is composed of the communication hole 221A and the internal space of the outer cylindrical portion 3 is This is the same as the above embodiment.

  (H) In the above-described embodiment, the end opening 8C is opened obliquely upward, but the end portion of the transmission member accommodating portion 82 is formed in a shape extending in the vertical direction, so that the end portion The opening 8C may be configured to open upward.

  (I) In the above embodiment, the support member 512 is configured to protrude from the outer peripheral side of the one end surface of the columnar portion 511, but the configuration of the support member is not limited to this. Therefore, for example, you may comprise so that a supporting member may protrude from the outer periphery of a cylindrical part.

  Further, in the above embodiment, the support member 512 is configured to move up and down by the rotation of the drive member 51. However, the support member is configured to move up and down when the drive member itself moves up and down. May be. For example, the drive member is configured to move in the diagonally up and down direction together with the transmission member, and the support member protruding from the drive member into the pipe 2 is moved in the diagonally up and down direction as the drive member moves in the diagonally up and down direction. It may be configured.

  (J) In the above embodiment, the driving member 51 and the transmission member 52 are connected, but it is sufficient that the driving force can be transmitted from the transmission member 52 to the driving member 51. There is no need to connect the two. Therefore, for example, a gear-shaped rack may be provided on the outer periphery of the drive member, while a rod-shaped rack having a plurality of teeth formed at one end of the transmission member, and the teeth of the rack may be engaged with the gear. Good.

  (K) In the above embodiment, the pipe 2 includes the drain port member 21 and the drain pipe 22, but the drain pipe may be directly fixed to the bathtub 100 without using the drain port member 21. In this case, the pipe is constituted only by the drain pipe.

  Moreover, the shape of the sealing part 23 in the said embodiment is an illustration, Comprising: As long as sealing water can be stored, the shape of a sealing part is not specifically limited.

  (L) In the above embodiment, the drain lid 103 is closed by the plug lid 73 (packing portion 732) coming into contact with the drain port member 21, but the plug lid 73 (packing portion 732) is You may comprise so that the drain outlet 103 may be closed by contacting the bottom wall part 101.
