In the present embodiment, the second component 63B is separate from the first component 63A and is configured to be separable from the first component 63A.

  Further, the lid member side bending guide member 5 provided on the outer periphery of the release wire 4 is rotatably attached to the case member 63. More specifically, since the flange portion 55 of the plug lid side bending guide member 5 is disposed in the groove portion 64, the case member 63 can be rotated while the stopper lid side bending guide member 5 is prevented from falling off. Installed. In this embodiment, when the plug lid-side bending guide member 5 is rotated in a state where the plug lid driving mechanism 6 is attached to the pipe 71, other than the plug lid-side bending guide member 5 with respect to the pipe 71, The end is in contact. That is, the plug lid side bending guide member 5 can be freely rotated with respect to the case member 63 before the plug lid driving mechanism 6 is attached to the pipe 71, but after the plug lid driving mechanism 6 is attached to the pipe 71. The stopper lid-side bending guide member 5 can be rotated only within a certain range with respect to the case member 63.

  Subsequently, the arrangement | positioning method of the drain plug apparatus 1 mentioned above is demonstrated.

  First, in a factory or the like, the release member 4 in which the fixing members 41A and 41B are provided on the transmission member 41 and the hook-shaped protrusions 42A and 42B are formed on the tube member 42 is manufactured.

  Next, similarly, in a factory or the like, a unit in which the stopper lid side bending guide member 5 and the release wire 4 are attached to the stopper lid driving mechanism 6 is assembled in advance.

  In assembling the unit, first, the stopper lid side bending guide member 5 is attached to the outer periphery of the release wire 4. That is, the release wire 4 (tube member 42) is disposed between the two divided portions 51 and 52 through the space between the other edge portions 51Y and 52Y while the other edge portions 51Y and 52Y are separated from each other. In addition, the tube member 42 is not positioned between the two split portions 51 and 52, or the tube member 42 is between the half groove portions 51B and 52B of the split portions 51 and 52. 42, the other edge portions 51Y and 52Y are brought close to each other, the engaging portion 31A is engaged with the engaged portion 52A, and both split portions are disposed. 51 and 52 are combined. Thereby, the stopper lid side bending guide member 5 is attached to the outer periphery of the release wire 4.

  Subsequently, the transmission member 41 is connected to the rack portion 62 </ b> A, and the stopper lid side bending guide member 5 is attached to the case member 63. First, the transmission member 41 is connected to the rack portion 62A in a state where both the constituent portions 63A and 63B (both concave portions 63C and 63E) of the case member 63 are separated from each other, and the plug lid side bend is formed between the concave portions 63C and 63E. The collar portion 55 of the guide member 5 is disposed (for example, the collar portion 55 is disposed in one of the concave portions 63C and 63E). Then, the second component 63B is attached to the first component 63A by bringing the second component 63B closer to the first component 63A and locking the projections 63D to the hole forming portion 63G. As a result, the transmission member 41 is connected to the rack portion 62A, and the plug lid-side bending guide member 5 is rotated with respect to the case member 63 in a state where the flange portion 55 is disposed in the groove portion 64 including both the concave portions 63C and 63E. A unit that is movably attached and in which the stopper cover side bending guide member 5 and the release wire 4 are attached to the stopper cover driving mechanism 6 is obtained.

  The assembly of the unit may be performed at a place other than the factory (for example, a place where the drain plug device 1 is installed).

  Next, using the obtained unit, the drain plug device 1 is attached at the place where the drain plug device 1 is installed.

  First, the shaft member 23 </ b> A is inserted into the guide member 21 from the opening at one end thereof. And after making the other end part (tip part) of shaft member 23A project from the other end side opening of guide part 21, knob part 23B is attached to shaft member 23A. Thereby, the displacement member 23 is attached to the guide member 21 in a state in which it cannot be removed. The displacement member 23 may be attached to the guide member 21 in advance at a factory or the like.

  Thereafter, one end portion of the shaft member 23A is protruded from the opening on one end side of the guide member 21, and the other end portion of the transmission member 41 is connected to one end portion of the shaft member 23A. After the transmission member 41 is connected, one end of the shaft member 23 </ b> A is accommodated in the guide member 21.

  Next, the operation side bending guide member 3 is attached to the guide portion 21. First, in a state where the edge portions 31Y and 32Y of both the split portions 31 and 32 in the operation side bending guide member 3 are separated from each other, one end portion of the guide member 21 and the release wire 4 ( The other end of the tube member 42) is disposed between the two divided portions 31 and 32. Next, the other end portion (the hook-like protrusion portion 42A) of the tube member 42 is disposed in one half groove portion 31B (32B) of both the divided portions 31 and 32, and both the divided portions are formed in the hollow portion 21C of the guide member 21. One half circumferential protrusion 31C (32C) of 31 and 32 is disposed. In this state, the other edge portions 31Y and 32Y are brought close to each other, the engaging portion 31A is engaged with the engaged portion 32A, and both the divided portions 31 and 32 are combined. As a result, the other end of the tube member 42 (the ridge-like protrusion 42A) is arranged in the annular groove 34 composed of both the half-grooves 31B and 32B, and both the semicircular protrusions 31C and 32C are arranged in the recess 21C. The As a result, the operation side bending guide member 3 is rotatably attached to one end portion of the guide portion 21 while holding the other end portion of the tube member 42.

  Next, the stopper cover driving mechanism 6 is attached to the pipe 71. That is, the claw portion 65 of the plug lid driving mechanism 6 is inserted into the through-hole portion provided in the mounting cylinder portion 71B of the pipe 71, and the claw portion 65 is locked to the mounting cylinder portion 71B. Thereby, the stopper cover driving mechanism 6 is attached to the pipe 71. Moreover, it will be in the state by which the support protrusion 66 is arrange | positioned in the piping 71 (piping main-body part 71A). Finally, the water passage member 72 provided with the support shaft 73 to which the stopper lid 75 is attached and the hair catcher 74 is inserted into the pipe 71, and the outer peripheral wall portion 72 </ b> A of the water passage member 72 is inserted into the support protrusion 66. The placement of the drain plug device 1 is completed by mounting.

  As described in detail above, according to the present embodiment, the bending device members 3 and 5 configured to be rotatable with respect to the operating device 2 and the plug lid driving mechanism 6 can control the operating device 2 and the release wire 4. The part which came out from the stopper cover drive mechanism 6 can be guided. Thereby, the release wire 4 can be reliably arranged in the target direction while being bent without waste. As a result, the release wire 4 can be more reliably prevented from interfering with surrounding members. In addition, in the state where the release wire 4 is arranged in the target direction, an excessive load is hardly applied to the release wire 4, and damage to the transmission member 41 can be effectively prevented.

  Furthermore, the part of the release wire 4 that has come out of the operating device 2 or the plug lid driving mechanism 6 is held by the bending guide members 3 and 5. Therefore, the arrangement stability of the release wire 4 can be improved.

  In addition, since the bending radius of the release wire 4 is approximately the same as the bending radius of the bending guide members 3 and 5, excessive bending of the release wire 4 can be more reliably prevented. As a result, damage or the like of the transmission member 41 can be prevented more effectively, and the smooth opening and closing of the drain port 104 can be achieved more reliably.

  Further, since the bending guide members 3 and 5 are constituted by two divided portions, the fixing members 41A and 41B and the hook-shaped protrusion portions 42A and 42B are provided at the end of the release wire 4 as in the present embodiment. Even so, the bending guide members 3 and 5 can be easily attached to the outer periphery of the release wire 4. In particular, in the present embodiment, since the two divided portions are connected, the bending guide members 3 and 5 can be attached to the outer periphery of the release wire 4 very easily (for example, with one touch). Therefore, the convenience at the time of assembly work (installation work) of the drain plug device 1 can be remarkably enhanced, and workability can be greatly improved.

  Further, since both the divided parts are connected, there is no inconvenience that occurs when both divided parts can be separated, for example, one of the divided parts is lost. Therefore, for example, the merit that the bending guide members 3 and 5 can be easily managed can be enjoyed.

  In addition, in this embodiment, the combination of the constituent parts 63A and 63B makes it possible to easily attach the plug lid-side bending guide member 5 to the plug lid driving mechanism 6 (case member 63). Therefore, the convenience at the time of the assembly work (installation work) of the drain plug device 1 can be further enhanced, and the workability can be further improved.

  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 bending guide members 3 and 5 can be attached to the outer periphery of the release wire 4 by being halved, but as shown in FIG. 9, the bending guide members 8 may be provided with a slit portion 81 penetrating from one end to the other end, and the bending guide member 8 may be attached to the outer periphery of the release wire 4 through the slit portion 81. In this case, the bending guide member 8 can be easily attached to the outer periphery of the release wire 4. Therefore, the convenience at the time of assembly work (at the time of attachment work) of the drain plug device 1 can be further enhanced, and workability can be improved.

  Further, by forming the bending guide member 8 from an elastically deformable material (for example, resin), the slit portion 81 always has a width smaller than the outer diameter of the release wire 4, while the bending guide member 8. The bending guide member 8 is attached to the outer periphery of the release wire 4 by arranging the release wire 4 on the inner periphery of the bending guide member 8 through the widened slit portion 81. You may do it. In this case, dropping of the bending guide member 8 from the release wire 4 can be more reliably suppressed while sufficiently securing ease of attachment of the bending guide member 8 to the release wire 4.

  The formation position of the slit portion is not particularly limited, but the slit portion 81 is preferably provided on the bending inner side 8U of the bending guide member 8. In this case, it is possible to more reliably suppress the release wire 4 from being detached from the bending guide member 8 through the slit portion 81.

  (B) In the above-described embodiment, the two divided parts 31 and 32 and the two divided parts 51 and 52 are connected by the connecting parts 33 and 53, and the two divided parts 31 and 32 and the two divided parts 51 and 52 are not separable. However, the connecting portion may not be provided, and the two divided portions may be configured to be separable.

  (C) In the above embodiment, the two constituent parts 63A and 63B of the case member 63 are configured to be separable, but as shown in FIG. 10, the two constituent parts 63A and 63B are connected by the case side connecting part 68. Alternatively, both the constituent parts 63A and 63B may be configured to be inseparable. In this case, the stopper cover side bending guide member 5 can be more easily attached to the stopper cover driving mechanism 6. In addition, for example, one of the constituent parts is lost, and there is no inconvenience caused by making both constituent parts separable. Therefore, it is possible to enjoy merits such as easy management of members.

  (D) In the above embodiment, after the stopper cover driving mechanism 6 is attached to the pipe 71, the stopper cover side bending guide member 5 can be rotated only within a certain range with respect to the case member 63. However, the plug lid side bending guide member 5 may be configured to be freely rotatable with respect to the case member 63 even after the plug lid driving mechanism 6 is attached to the pipe 71.

  Further, as in the above-described embodiment, the plug lid-side bending guide member 5 is freely rotatable with respect to the case member 63 before the plug lid driving mechanism 6 is attached to the pipe 71, while the plug lid for the pipe 71 is provided. After the drive mechanism 6 is mounted, when the plug lid-side bending guide member 5 can be rotated only within a certain range with respect to the case member 63, the plug lid drive mechanism 6 is fixed to the case member 63. Although it is possible to arrange them in a positional relationship before the stopper cover driving mechanism 6 is attached to the pipe 71, it is impossible after the stopper cover driving mechanism 6 is attached to the pipe 71.

  Therefore, using this point, FIG. 11 and FIGS. 12A and 12B [FIG. 12A is a cross-sectional end view taken along the line JJ of FIG. 11, and FIG. 11 is a cross-sectional end view taken along the line KK of FIG. 11. One or a plurality of convex portions 57 projecting radially outward are provided at one end portion of the stopper lid-side bending guide member 5 instead of the flange portion 55. In addition, the case member 63 and the plug lid-side bending guide member 5 can be disposed on the inner periphery of the outlet portion of the release wire 4 in the case member 63 before the plug lid driving mechanism 6 is attached to the pipe 71, while It is good also as providing the penetration part 67 which can pass the convex part 57 only when it is set as the positional relationship which cannot be arrange | positioned after the stopper cover drive mechanism 6 is attached. In this case, before the stopper cover driving mechanism 6 is attached to the pipe 71, the stopper part bending guide member 5 can be easily attached to the case member 63 by passing the convex part 57 through the penetration part 67. Can do. On the other hand, after the stopper cover driving mechanism 6 is attached to the pipe 71, the protrusion 57 cannot pass through the through-hole 67, so that the stopper cover-side bending guide member 5 is more reliably removed from the case member 63. Can be prevented. This technical idea may be applied to the operation side bending guide member 3 and the operation device 2.

  (E) In the above embodiment, the bending guide members 3 and 5 are attached to both the operating device 2 and the plug lid driving mechanism 6. That is, both the operating device 2 and the plug lid driving mechanism 6 are set as attachment objects. On the other hand, only one of the operating device 2 and the plug lid driving mechanism 6 may be an attachment object, and the bending guide member may be attached to only one of the operating device 2 and the plug lid driving mechanism 6.

  (F) In the above-described embodiment, the stopper cover driving mechanism 6 includes the movement direction conversion unit 62 that converts the reciprocating movement of the transmission member 41 into a rotational movement, but the stopper cover driving mechanism moves the stopper cover 75 up and down. It is sufficient if it has a function to be moved, and it is not always necessary to include a motion direction conversion unit. Moreover, in the said embodiment, although the stopper cover drive mechanism is arrange | positioned outside the piping 71, it may be arrange | positioned inside the piping 71. FIG. Therefore, as the plug lid driving mechanism, for example, a mechanism that supports the plug lid 75 and has a support shaft that reciprocates with the reciprocating motion of the transmission member 41 and is disposed in the pipe 71 may be used.

  (G) In the above embodiment, the displacement member 23 is displaced along the direction of the central axis thereof. However, the configuration of the displacement member is not limited to this, and, for example, rotates about the central axis as a rotation axis. It may be displaced by doing so.

  Further, the displacement member is not limited to a member that is displaced by being directly operated by the user, and may be a member that is electrically operated and displaced when the user touches a touch switch or the like, for example.

  (H) In the above embodiment, the drain plug device 1 is attached to the basin 100 as a tank body, but the attachment target of the drain plug device 1 is not limited to the basin, and other tank bodies (for example, , Bath tubs, unit baths, etc.).

  (I) In the above embodiment, both the bending guide members 3 and 5 are configured to be bent at substantially right angles, but the bending angle of the bending guide member is not particularly limited. The member may be bent in an obtuse or acute angle.

  (J) In the above embodiment, the transmission member 41 is directly connected to the operating device 2 and the plug lid driving mechanism 6, but is indirectly connected to the operating device 2 and the plug lid driving mechanism 6. It may be a configuration.
