A male screw portion 47 is formed on the outer periphery of the guide main body portion 44. The guide member 41 is inserted into the through-hole 22A from the surface side (washing area side) of the standing wall portion 28, and the male screw portion 47 is screwed into an annular mounting member 48 in which a female screw is formed on the inner periphery. It is in a state. Accordingly, the apron 22 (the standing wall portion 28) is sandwiched between the mounting member 48 and the flange portion 45, and the guide member 41 is attached to the standing wall portion 28.

  In addition, between the flange portion 45 and the surface of the standing wall portion 28, an annular seal member 5 that can be elastically deformed is disposed between the both. The seal member 5 prevents water from entering between the standing wall portion 28 and the guide member 41. An annular seal member 6 that can be elastically deformed is fitted into the end opening of the guide member 41 opposite to the flange 45. The seal member 6 prevents water that has entered the guide member 41 from leaking into the space between the standing wall portion 28 and the peripheral wall portion 25.

  The operation button 42 includes a plate-like pressed portion 49 that is exposed on the surface side (washing area side) of the standing wall portion 28. The operation button 42 is inserted inside the guide member 41 (a mounting hole 46 described later), and the pressed portion 49 extends inside the end of the guide member 41 (the mounting hole 46) along the axial direction of the guide member 41. And a reciprocating movement between a first position in a state of being arranged on the inner periphery of the opening and a second position in a state in which the pressed portion 49 is pushed deeper than the inside of the end portion. It has become. Further, the operation button 42 is always urged in the backward movement direction by the elastic member 51 compressed along the reciprocating direction.

  The pressed portion 49 is arranged at the first position in a state where the drain port 23 is closed. Further, at this time, the surface of the pressed portion 49 is configured to be substantially flush with the surface of the flange portion 45.

  On the other hand, in this state, the pressed portion 49 is pressed from the surface side (washing area side) of the standing wall portion 28, and the operation button 42 moves forward to a position exceeding a predetermined position (position slightly before the second position). When the pressing force on the pressed portion 49 is released in this state, the operation button 42 is operated so that the pressed portion 49 is pushed into the inner side (attachment hole 46) of the guide member 41 and the rotation ring or the rotation. It is locked in a non-returnable state by a lock mechanism 50 including a locked portion to which the ring is locked.

  Further, when the operation button 42 is locked and the pressed portion 49 is pressed again and the operation button 42 is moved forward to the predetermined position, the lock mechanism 50 is unlocked and the elastic member 51 is attached. The operation button 42 is moved back by the force. And the operation button 42 will stop in the state by which the to-be-pressed part 49 was arrange | positioned in said 1st position.

  In the present embodiment, the operation button 42 does not protrude from the guide member 41 and is always disposed inside the guide member 41. Therefore, it is possible to improve safety.

The transmission member 43 has one end attached to the operating device 4 (guide member 41) and the other end arranged on the inner periphery of the tubular tube member 7 attached to the drain plug device 3. 7 can be moved back and forth. The transmission member 43 has one end that can contact the operation button 42 and the other end that can contact the support shaft of the support shaft mechanism 31.

  In the state where the drain port 23 is closed, when the operation button 42 moves forward as the pressed portion 49 is pressed, the transmission member 43 moves forward in the tube member 7 in such a manner that it is pushed by the operation button 42. The support shaft and the plug lid 32 are moved upward to open the drain port 23. At this time, since the operation button 42 is locked by the lock mechanism 50 in a non-returnable state, the plug lid 32 is stopped at a predetermined upper position, and as a result, the drain port 23 is maintained open. .

  On the other hand, when the operation button 42 moves forward with the pressing of the pressed portion 49 in a state where the drain port 23 is opened, the lock of the operation button 42 is released. When the pressing force against the pressed portion 49 is released, the operation button 42 is moved back by the biasing force of the elastic member 51. As a result, the support shaft and the plug lid 32 are moved down by their own weight and the drainage port 23 is closed. As the support shaft moves downward, the transmission member 43 moves back in the tube member 7 and returns to the original position.

  Next, the shapes of the guide member 41 and the pressed part 49 will be described in more detail.

  First, the shape of the guide member 41 will be described. As shown in FIGS. 4 and 5 (both figures show a state in which the operation button 42 is locked), the guide member 41 has a rectangular inner surface in a cross section perpendicular to its central axis. It is configured. A mounting hole 46 having a rectangular shape in front view that opens to the surface side (washing area side) of the standing wall portion 28 is formed by the inner surface of the guide main body portion 44. That is, in this embodiment, the guide member 41 corresponds to the hole forming portion. Further, as described above, at least the surface portion of the guide member 41 from the outer peripheral edge of the collar portion 45 to the inner side surface thereof is made of a glossy metal member, so that the pressed portion 49 is behind the mounting hole 46. When the side is pushed in, the inner side surface of the glossy guide member 41 is exposed to the outside.

  Further, the opening forming portion 52 which is a portion for forming the opening on the surface side (washing station side) of the standing wall portion 28 on the inner side surface of the guide main body portion 44 has a rectangular shape, and the lowermost portion of the opening forming portion 52 is The linear straight portion 53 extending in the horizontal direction is provided. That is, when the operating device 4 is viewed from obliquely above, a portion corresponding to the lowermost portion of the opening forming portion 52 in the mounting hole 46 is easily visible to the farthest. A straight line portion 53 is provided. In addition, when the pressed portion 49 is viewed from the front (that is, viewed from the washing area side), the lowermost portion of the opening forming portion 52 has the maximum width in the opening forming portion 52. That is, the width along the horizontal direction of the lowermost portion of the opening forming portion 52 is configured to be equal to or greater than the width along the horizontal direction of other portions of the opening forming portion 52.

  Further, at the lower portion of the opening forming portion 52, two second straight portions 54A and 54B extending so as to intersect with the straight portion 53 (in the present embodiment, orthogonal) are provided. The second straight portion 54A extends upward from one end in the width direction of the straight portion 53, and the second straight portion 54B extends upward from the other end in the width direction of the straight portion 53. In the present embodiment, both the second straight portions 54 </ b> A and 54 </ b> B have the same length as the straight portion 53.

  The inner surface of the guide member 41 includes a flat first flat portion 55 continuous with the straight portion 53 and flat second flat portions 56A and 56B continuous with the second straight portions 54A and 54B. The first flat portion 55 has a horizontal plane shape, and the second flat portions 56 </ b> A and 56 </ b> B have a vertical plane shape extending from the width direction end portion of the first flat portion 55 in a direction orthogonal to the first flat portion 55. Between the first flat portion 55 and the second flat portion 56A, a bent portion 57 that is bent in the depth direction of the mounting hole 46 is formed. Although not shown, a bent portion extending in the depth direction of the mounting hole 46 is also formed between the first flat portion 55 and the second flat portion 56B.

  Next, the shape of the pressed part 49 will be described. The pressed portion 49 has a shape corresponding to the opening of the mounting hole 46. In the present embodiment, the pressed portion 49 has a rectangular shape having substantially the same size as the opening of the mounting hole 46.

  Further, a linear corresponding straight line portion 58 corresponding to the straight line portion 53 and a straight second corresponding straight line portion 59 corresponding to the second straight line portion 54A exist at the outer edge of the surface of the pressed portion 49. . The corresponding straight line portion 58 is a portion that is always maintained in parallel with the straight line portion 53, and the second corresponding straight line portion 59 is a portion that is always maintained in parallel with the second straight line portion 54A. Although not illustrated, a linear second corresponding linear portion corresponding to the second linear portion 54B exists on the outer edge of the pressed portion 49, and the second corresponding linear portion and the second corresponding linear portion The straight portion 54B is always maintained in a parallel state.

  As described above in detail, according to this embodiment, the pressed portion 49 has an outer edge shape corresponding to at least the opening of the mounting hole 46, and the lowermost portion of the opening forming portion 52 is a straight line. A portion 53 is provided. Therefore, in a state where the pressed portion 49 is pushed into the back side of the mounting hole 46, the straight portion 53 and the corresponding straight portion 58 that are in a parallel state when the operating device 4 is viewed obliquely from above are easily provided. Can be visually recognized. Then, based on the two parallel straight portions 53 and the corresponding straight portions 58, a portion corresponding to the lowermost portion of the lowermost portion of the opening forming portion 52 and the outer edge of the pressed portion 49 has a curved shape. As compared with the above, it becomes easier to clearly grasp the positional relationship between the opening forming portion 52 and the pressed portion 49. As a result, the pressed portion 49 in the pushed-in state can be recognized more easily, and convenience can be improved.

  Further, the lower portion of the inner side surface of the guide member 41 is visually recognized over a wider range as compared with the case where the opening of the mounting hole 46 has a circular shape having the same diameter as the length (width) of the lowermost portion of the opening forming portion 52. It becomes possible. Thereby, the to-be-pressed part 49 of the pushed-in state can be recognized more easily, and the convenience can be improved further.

  Further, the lowermost portion of the opening forming portion 52 having the straight portion 53 has the maximum width in the opening forming portion 52. Therefore, when the operating device 4 is viewed obliquely from above, the straight portion 53 and the corresponding straight portion 58 can be more easily visually recognized. As a result, it is possible to more easily recognize the pressed portion 49 in the pressed state, and it is possible to obtain better convenience.

  In addition, when the pressed portion 49 is pushed in, in addition to the straight portion 53 and the corresponding straight portion 58, the second straight portion 54A and the second corresponding straight portion 59, the second straight portion 54B and the corresponding portion The second corresponding straight line portion appears in parallel. Therefore, it becomes easier to grasp the positional relationship between the opening forming portion 52 and the pressed portion 49 more clearly. As a result, it can be recognized more easily that the pressed portion 49 is being pushed in, and the convenience can be further improved.

  In addition, by using the bent portion 57 (for example, the length of the bent portion 57) as a mark, the position of the pressed portion 49 can be grasped more easily. Thereby, it can recognize more easily that it is the state by which the to-be-pressed part 49 was pushed in, and can improve the convenience more effectively.

  Further, when the lower part of the inner surface of the guide member 41 has a curved surface shape, the inner surface of the guide member 41 becomes difficult to see due to the influence of light reflected from the curved surface (the inner surface of the guide member 41 is blurred). In particular, when the inner side surface of the guide main body 44 is made of a glossy metal member as in the present embodiment, the guide member 41 is not visible. It is conceivable that the inner surface becomes more difficult to see. However, according to the present embodiment, the first flat portion 55 and the second flat portions 56A and 56B are provided on the inner surface of the guide member 41. Therefore, the light reflection state (reflection direction, etc.) at the lower part of the inner side surface of the guide member 41 can be easily understood. As a result, by utilizing the state of reflected light or the like, it can be recognized more easily that the pressed portion 49 is being pushed.

  Further, in the present embodiment, the operation button 42 can be made relatively unrotatable with respect to the guide member 41. Therefore, with the relative rotation of the operation button 42, a situation in which the finger moves (turns) in a direction orthogonal to the pressing direction when the pressed portion 49 is pressed does not occur. Thereby, the further improvement of operativity can be aimed at. Further, when the operation button 42 becomes relatively unrotatable, for example, when information such as characters or figures (for example, logos, trademarks, etc.) is attached to the surface of the pressed part 49, the information of the attached information is displayed. Tilt and rotation can be prevented. Therefore, it is possible to improve information visibility and appearance quality.

  In addition, you may employ | adopt the structure which the guide member 41 becomes relatively unrotatable with respect to the standing wall part 28 at the time of an assembly. The configuration in which the guide member 41 cannot rotate relative to the standing wall portion 28 is realized, for example, by providing a recess having a shape corresponding to the flange portion 45 in the standing wall portion 28 and arranging the flange portion 45 in the recess. can do. Moreover, the through hole 22A is formed in a square shape (for example, a square shape), and the outer peripheral shape of the guide member 41 inserted through the through hole 22A is a shape corresponding to the through hole 22A. It is also possible to make the relative rotation impossible.

  Furthermore, you may comprise so that both the guide member 41 and the operation button 42 may become relatively unrotatable with respect to the standing wall part 28. FIG. In this case, for example, when information is attached from the surface of the guide member 41 (the flange portion 45) to the surface of the pressed portion 49, it is possible to improve information visibility and appearance quality.

  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 opening forming portion 52 has a rectangular shape, but the shape of the opening forming portion is particularly limited as long as the lowermost portion of the opening forming portion includes a linear straight portion. is not. Therefore, for example, the opening forming portion may be triangular, pentagonal, trapezoidal, parallelogram shape, or the like.

  Further, for example, as shown in FIGS. 6 and 7, the inner surface of the guide member 66 has a hexagonal cross section so that the mounting hole 64 has a hexagonal shape. As a result, the opening forming portion 61 has a hexagonal shape. You may comprise as follows. In this case, the lowermost portion of the opening forming portion 61 includes a linear straight portion 62, and the lower portion of the opening forming portion 61 includes two second straight portions 67 </ b> A that intersect the obtuse angle with the straight portion 62. 67B (“obtuse angle” means that the angle of the angle formed on the center side of the mounting hole 64 out of the angle formed by the straight part 62 and the second straight parts 67A, 67B is an obtuse angle. Means that). Further, the pressed portion 63 has a hexagonal shape whose outer edge corresponds to the shape of the mounting hole 64, and a linear corresponding straight portion 65 corresponding to the straight portion 62, A straight second corresponding straight line portion 68A corresponding to the two straight line portions 67A and a straight second corresponding straight line portion 68B corresponding to the second straight line portion 67B are provided.
