加えて、前記キャップ部２５のうち本体部２２の一端側内周部に配置される端部（内周側端部）２５Ｅは、前記大径部２２Ａの内周に配置され、大径部２２Ａの内周面に密着するように構成されている。従って、キャップ部２５の内周側端部２５Ｅは、小径部２２Ｂの内周面よりも外周側に位置しており、小径部２２Ｂの内周面よりも内周側に突出しないように構成されている。   In addition, an end portion (inner peripheral side end portion) 25 </ b> E that is disposed on one end side inner peripheral portion of the main body portion 22 in the cap portion 25 is disposed on the inner periphery of the large diameter portion 22 </ b> A, and the large diameter portion 22 </ b> A. It is comprised so that it may closely_contact | adhere to the inner peripheral surface. Therefore, the inner peripheral side end 25E of the cap portion 25 is located on the outer peripheral side with respect to the inner peripheral surface of the small diameter portion 22B, and is configured not to protrude to the inner peripheral side from the inner peripheral surface of the small diameter portion 22B. ing.

加えて、本実施形態では、前記円板部４１の外周面における最他端部（最下方部）４１Ｅが、前記ガイド部材２のうち大径部２２Ａ及び小径部２２Ｂを連接する段部２２Ｃよりも常に他端側（下方側）に位置するように構成されている。すなわち、排水口１０４の開閉のために操作ボタン４の位置は変動するが、操作ボタン４がどの位置にあっても円板部４１の外周面における最他端部４１Ｅは、段部２２Ｃよりも他端側に位置するように構成されており、段部２２Ｃよりも一端側（上方側）に位置しないように構成されている。   In addition, in the present embodiment, the outermost end portion (lowermost portion) 41E on the outer peripheral surface of the disc portion 41 is more than the step portion 22C connecting the large diameter portion 22A and the small diameter portion 22B of the guide member 2. Is always located on the other end side (lower side). That is, the position of the operation button 4 varies for opening and closing the drain port 104, but the other end 41E on the outer peripheral surface of the disc portion 41 is more than the step portion 22C, regardless of the position of the operation button 4. It is comprised so that it may be located in the other end side, and it is comprised so that it may not be located in one end side (upper side) rather than the step part 22C.

以上詳述したように、本実施形態によれば、キャップ部２５の内周側端部２５Ｅは、大径部２２Ａの内周に配置されるとともに、小径部２２Ｂの内周面よりも外周側に位置するように構成されている。従って、長期間の使用等により、前記内周側端部２５Ｅが本体部２２（大径部２２Ａ）の内周面から多少離間したとしても、前記内周側端部２５Ｅは操作ボタン４へと干渉しにくくなる。その結果、内周側端部２５Ｅが操作ボタン４に干渉することに伴う、外観品質や操作性の低下といった事態をより確実に防止することができる。   As described above in detail, according to the present embodiment, the inner peripheral side end 25E of the cap portion 25 is disposed on the inner periphery of the large diameter portion 22A and is further on the outer peripheral side than the inner peripheral surface of the small diameter portion 22B. It is comprised so that it may be located in. Therefore, even if the inner peripheral end 25E is somewhat separated from the inner peripheral surface of the main body 22 (large diameter portion 22A) due to long-term use, the inner peripheral end 25E is moved to the operation button 4. It becomes difficult to interfere. As a result, it is possible to more reliably prevent the appearance quality and the operability from being deteriorated due to the inner peripheral side end 25E interfering with the operation button 4.

特に本実施形態のように、キャップ部２５が、その外周側端部を屈曲させることで、ガイド部材２に対して加締めに固定される構成においては、キャップ部２５の内周側端部２５Ｅが内周側に比較的変形しやすくなるため、操作ボタン４に対する前記内周側端部２５Ｅの干渉が懸念されるが、本実施形態によれば、このような懸念を払拭することができる。換言すれば、上述の構成は、キャップ部２５の外周側端部が屈曲されることで、ガイド部材２に対してキャップ部２５が加締め固定される構成において、特に有効である。   Particularly in the configuration in which the cap portion 25 is fixed to the guide member 2 by caulking by bending the outer peripheral side end portion as in the present embodiment, the inner peripheral side end portion 25E of the cap portion 25. However, according to this embodiment, such a concern can be wiped out. However, according to the present embodiment, there is a concern that the inner peripheral side end 25E interferes with the operation button 4. In other words, the above-described configuration is particularly effective in a configuration in which the cap portion 25 is caulked and fixed to the guide member 2 by bending the outer peripheral side end portion of the cap portion 25.

さらに、本実施形態では、操作ボタン４の位置に関わらず、円板部４１の外周面の最他端部４１Ｅは、常に段部２２Ｃよりも他端側（下方側）に位置するように構成されている。従って、操作ボタン４の移動時に、円板部４１の最他端部４１Ｅが段部２２Ｃに接触（干渉）してしまうことをより確実に防止できる。その結果、良好な操作性を実現することができる。   Furthermore, in the present embodiment, regardless of the position of the operation button 4, the outermost end portion 41 </ b> E on the outer peripheral surface of the disc portion 41 is always positioned on the other end side (lower side) with respect to the stepped portion 22 </ b> C. Has been. Therefore, when the operation button 4 is moved, it is possible to more reliably prevent the outermost end portion 41E of the disc portion 41 from contacting (interfering) with the stepped portion 22C. As a result, good operability can be realized.
