また、別のパターンとして、シャワヘッド５を正面からみてシャワ板５ｅが図２に示すような水平になる状態だけのものでもよい。この場合を、図８，９に示す。図８，９において、シャワヘッド５をシャワ受け１に対し所定位置に位置決めしうるための位置決め手段は、前記差し込み保持部８の外周面の接触面に設けた縦断面略台形形状の単一の凸部２５（図８参照）と、前記シャワヘッド５の基部５ａの内周面の接触面に設けた、隣接する二つの縦断面略台形形状の凸部２６，２６間に形成される凹部２７とで構成されている。そして、図８で示した場合も、また、図５で示した実施の形態の場合も、差し込み保持部８の凹凸部２０，２１、２２，２３や、凸部２５が上側に位置するよう、かつ、セレーション１７が下側（水抜き穴１３および係合爪１４が位置する側）に位置するようにシャワ受け１はシャワホルダ６に取り付けられる。 Further, the base portion 5a and the insertion holding portion 8 of the shower head 5 have positioning means for positioning the shower head 5 with respect to the shower receiver 1, and this positioning means is the embodiment. Then, a plurality of concave and convex portions 20, 21, 22 having a longitudinal section gear shape provided on the contact surface 8 a on the outer peripheral surface of the insertion holding portion 8 and the contact surface 5 a ′ on the inner peripheral surface of the base portion 5 a of the shower head 5. , 23 (see FIGS. 5 and 7). That is, in the base portion 5a shown in FIG. 7, for example, five concave portions 22 are formed along the circumferential direction, for example, at intervals of a circumferential angle of 30 °, and each of the concave portions 22 is an axis of the base portion 5a. A total of four convex portions 23 having a predetermined length L in the core direction and formed on the contact surface 5a ′ and formed between the concave portions 22 and 22 are spaced at a circumferential angle of, for example, 30 °. Thus, each of the convex portions 23 is formed to have substantially the same length as the length L of the concave portion 22 in the axial direction of the base portion 5a.
On the other hand, in the insertion holding part 8, for example, two recesses 20 (see FIG. 4) are arranged along the circumferential direction, for example, at intervals of a circumferential angle of 30 °, and each recess 20 is inserted and held. The three convex portions 21 having a length substantially the same as the length L of the concave portion 22 in the axial direction of the portion 8 and formed on the contact surface 8a and forming the concave portion 20 are 30 ° circles. Each of the convex portions 21 is formed so as to have substantially the same length as the length of the convex portion 23 in the axial direction of the insertion holding portion 8 with a circumferential angle interval. And in this embodiment, the said convex parts 23 and 21 make a longitudinal cross-section substantially trapezoid shape.
Accordingly, when the base portion 5a of the shower head 5 is inserted into the insertion holding portion 8, the shower head 5e is shown in FIG. It can be used properly in a state as shown in the figure, a state where the shower plate 30 is inclined 30 ° to the right when viewed from the front, and a state where the shower plate 5e is inclined 30 ° to the left as viewed from the front. Therefore, it is advantageous in that the head does not interfere with the shower head 5 by tilting the shower head 5 to the left or right during hair washing. The inclination angle of the shower plate 5e is not limited to 30 ° on the left and right, and can be set as appropriate.
As another pattern, the shower head 5e may be in a horizontal state as shown in FIG. 2 when the shower head 5 is viewed from the front. This case is shown in FIGS. 8 and 9, the positioning means for positioning the shower head 5 at a predetermined position with respect to the shower receiver 1 is a single piece having a substantially trapezoidal cross section provided on the contact surface of the outer peripheral surface of the insertion holding portion 8. A convex portion 25 (see FIG. 8) and a concave portion 27 formed between the adjacent two convex portions 26 and 26 having a substantially trapezoidal cross section provided on the contact surface of the inner peripheral surface of the base portion 5a of the shower head 5. It consists of and. And in the case shown in FIG. 8 and also in the case of the embodiment shown in FIG. 5, the concave and convex portions 20, 21, 22, 23 of the insertion holding portion 8 and the convex portion 25 are positioned on the upper side. In addition, the shower receiver 1 is attached to the shower holder 6 so that the serrations 17 are located on the lower side (the side on which the drain holes 13 and the engaging claws 14 are located).

また、前記回転防止部分１１は、シャワ受け１の軸芯まわりの回転を防止するためシャワホルダ６の内周面においてシャワホルダ軸芯方向に沿って形成された左右一対で長さｈの嵌合溝３１に嵌合する長さＨ（ｈ＞Ｈ）の嵌合突起３２，３２を有する。
また、前記シャワ受け抜止部分１２は、シャワホルダ６の内周面との間に位置して水密的にシールするシール部材（例えばＯリング）３４が装着される環状溝３３を、前記係合爪１４の上流側に形成された一対の外向きフランジ３５，３６間に有する。

また、図５（Ａ）に示すように、シャワ受け１の前記差し込み保持部８の内径Ｒよりも前記シャワ受け抜止部分１２の内径ｒが小さく設定されており、小さく設定された前記シャワ受け抜止部分１２の内径ｒは、前記ホース４の最大外径に設定されている。そして、たとえ、差し込み保持部８側から湯水が進入してきても、シャワ受け抜止部分１２における挿通穴７で湯水の進入を阻止するため、前記ホース４の最大外径の公差と、前記シャワ受け抜止部分１２の内径ｒの公差が考慮されている。 Further, as shown in FIG. 5A, the inner diameter r of the shower receiving / preventing portion 12 is set smaller than the inner diameter R of the insertion holding portion 8 of the shower receiving 1, and the shower receiving prevention that is set to be smaller is set. The inner diameter r of the portion 12 is set to the maximum outer diameter of the hose 4. And even if hot water enters from the insertion holding portion 8 side, the tolerance of the maximum outer diameter of the hose 4 and the shower receiving stop are prevented in order to prevent the hot water from entering through the insertion hole 7 in the shower receiving stop portion 12. The tolerance of the inner diameter r of the part 12 is taken into account.

また、図５（Ａ）に示すように、シャワ受け１の出口端部である前記差し込み保持部８の下流端部における内周面Ｍが上流にいくほど先細りの環状のテーパ面に形成されており、かつ、シャワ受け１の入口端部である前記シャワ受け抜止部分１２の上流端部における内周面Ｎが上流にいくほど先太りの環状のテーパ面に形成されている。そのため、前記のテーパ面Ｍ，Ｎが備わっていない場合に比べて、ホース４の収納性能ならびに引出し性能を向上できる。 Further, as shown in FIG. 5A, the inner peripheral surface M at the downstream end portion of the insertion holding portion 8 which is the outlet end portion of the shower receiver 1 is formed in an annular tapered surface that tapers toward the upstream side. In addition, the inner peripheral surface N at the upstream end portion of the shower receiving stop portion 12 that is the inlet end portion of the shower receiver 1 is formed in an annular tapered surface that becomes tapered toward the upstream. Therefore, compared with the case where the taper surfaces M and N are not provided, the storage performance and the drawing performance of the hose 4 can be improved.

さらに、図１，３，４および図５（Ａ），図５（Ｂ），図５（Ｅ）に示すように、シャワ受け１の出口端部である前記差し込み保持部８の下流端部における外周面Ｐが上流にいくほど先細りの環状のテーパ面に形成されている。そのため、シャワ受け１をシャワヘッド５の基部５ａにスムーズに差し込みことができる。前記のテーパ面９が備わっていない場合に比べて、シャワヘッド５のシャワ受け１への挿入（収納）性能を向上できる。 Further, as shown in FIGS. 1, 3, 4 and FIGS. 5A, 5B, and 5E, at the downstream end portion of the insertion holding portion 8 that is the outlet end portion of the shower receiver 1. The outer peripheral surface P is formed in an annular tapered surface that tapers toward the upstream. Therefore, the shower receiver 1 can be smoothly inserted into the base portion 5 a of the shower head 5. Compared with the case where the tapered surface 9 is not provided, the insertion (storage) performance of the shower head 5 into the shower receiver 1 can be improved.

前記凹部５０は差し込み保持部８の外周面ｎ上に環状に形成されている一方、前記止め輪５４は径方向に弾性変形可能なＣリングであり、また、前記爪５１が保持孔５２に挿入された状態ではシャワヘッドの基部５ａの外周面Ｒと爪５１の保持部５７の最外周面ｔとが面一となるよう構成されている。
また、シャワヘッドの基部５ａは、Ｃリング５４が嵌込み可能に形成された溝６０を保持孔５２，５２に連通するよう外周面Ｒに有する（図１５参照）とともに、爪５１は、保持孔５２に挿入された状態でＣリング５４が嵌込み可能に形成された溝６１を保持部５７の外周面に有し、さらに、両溝６０，６１に嵌込まれたＣリング５４がシャワヘッドの基部５ａの外周面Ｒおよび爪５１の保持部５７の最外周面ｔと面一になるよう構成されている。
また、シャワ受け１の出口端部である前記差し込み保持部８の下流端部における外周面Ｐが上流にいくほど先細りの環状のテーパ面に形成されている。そのため、シャワ受け１をシャワヘッド５の基部５ａにスムーズに差し込みことができ、前記テーパ面Ｐが備わっていない場合に比べて、シャワヘッド５のシャワ受け１への挿入（収納）性能を向上できる。 The concave portion 50 is formed in an annular shape on the outer peripheral surface n of the insertion holding portion 8, while the retaining ring 54 is a C ring that can be elastically deformed in the radial direction, and the claw 51 is inserted into the holding hole 52. In this state, the outer peripheral surface R of the base portion 5a of the shower head and the outermost peripheral surface t of the holding portion 57 of the claw 51 are configured to be flush with each other.
Further, the base 5a of the shower head has a groove 60 formed on the outer peripheral surface R so that the C-ring 54 can be fitted into the holding holes 52, 52 (see FIG. 15), and the claw 51 has a holding hole. A groove 61 is formed on the outer peripheral surface of the holding portion 57 so that the C-ring 54 can be fitted in the state where the C-ring 54 is inserted, and the C-ring 54 fitted in both the grooves 60 and 61 is used for the shower head. The outer peripheral surface R of the base portion 5a and the outermost peripheral surface t of the holding portion 57 of the claw 51 are configured to be flush with each other.
Further, the outer peripheral surface P at the downstream end portion of the insertion holding portion 8 which is the outlet end portion of the shower receiver 1 is formed into an annular tapered surface that tapers toward the upstream side. Therefore, the shower receiver 1 can be smoothly inserted into the base portion 5a of the shower head 5, and the insertion (storage) performance of the shower head 5 into the shower receiver 1 can be improved as compared with the case where the tapered surface P is not provided. .

また、この実施の形態では、シャワヘッド５を正面からみてシャワ板５ｅが図１０に示すような水平になる状態に設定されている。図１３、図１５（Ｄ）において、シャワヘッド５をシャワ受け１に対し所定位置に位置決めしうるための位置決め手段は、前記差し込み保持部８の外周面に設けた縦断面略台形形状の単一の線状凸部２５と、前記シャワヘッド５の基部５ａの内周面に設けた、隣接する二つの縦断面略台形形状の凸部２６，２６間に形成される凹部２７とで構成されている。 Further, in this embodiment, the shower plate 5e is set in a horizontal state as shown in FIG. 10 when the shower head 5 is viewed from the front. In FIG. 13 and FIG. 15 (D), the positioning means for positioning the shower head 5 at a predetermined position with respect to the shower receiver 1 is a single unit having a substantially trapezoidal cross section provided on the outer peripheral surface of the insertion holding portion 8. And a concave portion 27 formed between the adjacent two convex portions 26 and 26 each having a substantially trapezoidal shape in the longitudinal section provided on the inner peripheral surface of the base portion 5a of the shower head 5. Yes.

而して、シャワヘッド５の基部５ａを介してシャワヘッド５がシャワ受け１に差し込まれたときに音が鳴るように構成したので、確実にシャワヘッド５がシャワ受け１に差し込まれていることが判明する。すなわち、図１８（Ａ）に示す状態から、差し込み保持部８をシャワヘッドの基部５ａに差し込む。この差し込み初期においては、差し込み保持部８によって、爪５１の突部５３を外側に押し上げる。この状態で差し込み保持部８が差し込み方向に移動していくと、差し込み保持部８による突部５３の押し上げ力が解除されて爪５１の前記突部５３が前記凹部５０に係合する〔図１８（Ｂ）参照〕。そして、突部５３が凹部５０に係合するときに突部５３が凹部５０に当たることにより音が鳴る。そのため、音が鳴ることで、シャワ受け１のシャワヘッド５への差し込み状態を確認できる。
また、シャワ受け１の差し込み保持部８は、当該差し込み保持部８に保持された状態でのシャワヘッド５のぐら付きを防止するためシャワヘッドの基部５ａの内周面に設けたセレーション１６に噛合するセレーション１７を外周面ｎの一部に有している。そして、シャワヘッド５が差し込み保持部８に保持されている状態では、両セレーション１６，１７の噛合に加えて、クリック機構による前記凹凸係合が加わるので、前記凹凸係合が加わった分シャワ受け１に保持されているシャワヘッド５のぐら付きの防止効果を高めることができる。すなわち、両セレーション１６，１７の噛合とクリック機構による前記凹凸係合の相乗効果により、シャワ受け１に保持されているシャワヘッド５のぐら付きを確実に防止できる。 Thus, since the sound is generated when the shower head 5 is inserted into the shower receiver 1 via the base portion 5a of the shower head 5, the shower head 5 is securely inserted into the shower receiver 1. Becomes clear. That is, from the state shown in FIG. 18A, the insertion holding portion 8 is inserted into the base portion 5a of the shower head. In the initial stage of insertion, the projection 53 of the claw 51 is pushed up by the insertion holding portion 8. When the insertion holding part 8 moves in the insertion direction in this state, the pushing-up force of the protrusion 53 by the insertion holding part 8 is released, and the protrusion 53 of the claw 51 engages with the recess 50 [FIG. (See (B)). When the protrusion 53 engages with the recess 50, a sound is produced when the protrusion 53 hits the recess 50. Therefore, it is possible to confirm the insertion state of the shower receiver 1 into the shower head 5 by making a sound.
Further, the insertion holding portion 8 of the shower receiver 1 meshes with a serration 16 provided on the inner peripheral surface of the base portion 5a of the shower head in order to prevent wobbling of the shower head 5 while being held by the insertion holding portion 8. Serration 17 is provided on a part of the outer peripheral surface n. In the state where the shower head 5 is held by the insertion holding portion 8, in addition to the engagement of the two serrations 16 and 17, the uneven engagement by the click mechanism is added. The wobbling prevention effect of the shower head 5 held by 1 can be enhanced. In other words, the wobbling of the shower head 5 held by the shower receiver 1 can be reliably prevented by the synergistic effect of the engagement of the serrations 16 and 17 and the uneven engagement by the click mechanism.

この実施の形態では、爪５１の突部５３を凹部５０に付勢する部材として、止め輪５４を用いている。止め輪５４を用いる代わりに、板バネを用いることも考えられる。例えば、凹部５０に係合する突部５３を中央に有して両端が折り曲げられてなる板バネを考えた場合、その板バネの固定手法として、シャワヘッドの基部（インナー部材）５ａに受溝を形成し、この受溝内に板バネの両端を係合固定することが考えられる。そのように構成した場合、受溝形成のために基部５ａの厚みを止め輪５４を用いる場合よりも厚くする必要があり、そのために、インナー部材５ａの外径を大きくしなければならない。よって、スペース的に問題である。この場合、シャワヘッドのグリップ部５ｂ（図１参照）の大きさを維持できるのか否かが課題としてあがる。維持できるにしても、板バネはＣリング等の止め輪５４に比べて耐久性に劣る。このような理由により、本発明者らはインナー部材５ａの外径を変更する必要はなく、かつ、耐久性がある止め輪を採用したのである。 In this embodiment, a retaining ring 54 is used as a member that biases the protrusion 53 of the claw 51 toward the recess 50. Instead of using the retaining ring 54, a leaf spring may be used. For example, when considering a leaf spring that has a protrusion 53 that engages with the recess 50 at the center and is bent at both ends, a receiving groove is formed in the base (inner member) 5a of the shower head as a method for fixing the leaf spring. It is considered that both ends of the leaf spring are engaged and fixed in the receiving groove. In such a configuration, it is necessary to make the thickness of the base portion 5a thicker than that in the case where the retaining ring 54 is used for forming the receiving groove, and therefore, the outer diameter of the inner member 5a must be increased. Therefore, it is a space problem. In this case, whether or not the size of the grip portion 5b (see FIG. 1) of the shower head can be maintained is raised as a problem. Even if it can be maintained, the leaf spring is inferior in durability to the retaining ring 54 such as a C-ring. For these reasons, the present inventors do not need to change the outer diameter of the inner member 5a and employ a durable retaining ring.

また、この実施の形態では、保持孔５２を二つ設けたものを示したが、この発明はこれに限定されるものではなく、単一の保持孔でもよく、すなわち、一つの爪を用いてもよく、また、設計可能な範囲で三つ以上の保持孔を設け、三つ以上の爪を用いてもよい。 In this embodiment, two holding holes 52 are provided.
