【従来の技術】
本出願人は、カバー体と、このカバー体の開口から内部に挿入される水栓本体の胴とを備えた壁付きタイプの湯水混合水栓を開発中である。これは、カバー体を陶磁性材料で構成することにより、従来より用いられていたステンレス等の加工性の良い金属や合成樹脂などでは得られなかった和風の外観や独特の重量感，肌触りが実現でき、水栓本体の胴に湯配管用継手および水配管用継手を取り付けるのに、これら継手が挿通可能な二つの穴を前記カバー体に形成するというものである。
【０００３】
【発明が解決しようとする課題】
ところで、前記陶磁性材料のカバー体に形成される前記二つの穴の加工精度は水栓本体の胴に形成される前記両継手の取付穴の加工精度よりも劣るので、前記二つの穴間のピッチと前記二つの取付穴間のピッチが必ずしも一致せず、前記カバー体に前記胴を挿入しても最悪の場合、前記継手を取り付けるのが難しいという問題があった。
【０００４】
この発明は上述の事柄に留意してなされたもので、その目的は、水栓本体に取り付けられる湯配管用継手および水配管用継手間のピッチの調整を行える湯水混合水栓を提供することである。

【００３０】
また、栓棒２２は、操作部材３７に連動連結される操作棒２２ａと、可動ディスク１９に連動連結されるディスク棒２２ｂよりなる。操作棒２２ａは、内周面にＡ方向に沿って形成されたセレーションを有する筒状の溝６０を内側に有し、ディスク棒２２ｂは、このセレーションに係合するセレーションが外周面に形成されている突起部６１を外側に有する。したがって、前記両部材５１，５２を近接させたり、離間させるときに溝６０内を突起部６１がＡ方向に沿ってシフトすることになる。

一方、連結体５３は、筒状で、周面Ｆにおける中央の位置に、同じ大きさの矩形の四つの接続孔６３を円周方向に等間隔で有する。この接続孔６３の大きさは、吐水管用継手取り付け用穴５５を有する部材５６を、図９に示すように連結体５３に挿入したときに接続孔６３の上方から吐水管用継手取り付け用穴部５５に吐水管用継手４０が接続できる大きさに設定されている。更に、連結体５３は、周面Ｆの内側で接続孔６３の両端側に一対の雌ねじ６４，６５を有する。雌ねじ６４，６５のうち、部材５１側の雌ねじ６４は例えば左ねじに形成されており、一方、部材５２側の雌ねじ６５は例えば右ねじに形成されている。そして、雌ねじ６４を部材５１の雄ねじＧに螺合するとともに、雌ねじ６５を部材５２の雄ねじＧに螺合した状態で連結体５３を例えば時計方向（Ｊ方向）に回すと両部材５１，５２が近接するよう移動する一方、連結体５３を例えば反時計方向（Ｋ方向）に回すと両部材５１，５２が離間するよう移動することになる。これにより、湯配管用継手８および水配管用継手９間のピッチＰを可変可能に構成できる。８０は、両部材５１，５２の各雄ねじＧに螺合する一対のロックナットで、ピッチＰを調整した後連結体５３を固定するためのものであるが、必ずしも必要ではない。
【００３４】
次に、吐水管用継手４０の取り付け位置が可変調整可能に構成される機構について説明する。
【００３５】
吐水管用継手取り付け用穴５５は、筒状体５５ａの周面を貫通して形成されている。この筒状体５５ａの両側面に筒状体５５ａよりも小径の連通部７０，７０が設けられている。この連通部７０は外周面に一対のＯリング７１，７１を有する。この連通部７０はＯリング７１，７１を介して両部材５１，５２のそれぞれ雄ねじ部５１ｃ，５２ｃにＡ方向に摺動可能に挿入されている。したがって、湯配管用継手８および水配管用継手９間のピッチ調整とは別に、吐水管用継手取り付け用穴５５を有する部材５６をＡ方向に摺動することにより、吐水管用継手４０の取り付け位置を変更できる。
【００３６】
なお、この発明では、陶器カバー体３の代わりに、高硬度金属（ハステロイ，チタン，マグネシウム等）やエラストマー樹脂，繊維（ヤシ繊維等），木材よりなるカバー体３を用いてもよい。
【００３７】
