主弁部12は、バルブケーシング13を有している。バルブケーシング13は、長四角ブロック状である。バルブケーシング13は、バルブボディ14と、第1連結ブロック15と、第2連結ブロック16と、を有している。バルブボディ14は、長四角ブロック状である。第1連結ブロック15は、バルブボディ14の長手方向の第1端に連結されている。第2連結ブロック16は、バルブボディ14の長手方向の第2端に連結されている。バルブボディ14は、ベース部30に対向する本体対向面14aを有している。
ベース部30は、マニホールドブロック31を有している。マニホールドブロック31は、長四角ブロック状である。マニホールドブロック31は、載置面31aを有している。載置面31aには、電磁弁11が搭載されている。マニホールドブロック31の長手方向は、バルブケーシング13の長手方向に一致している。
制御部40は、マニホールドブロック31に内蔵されている。したがって、ベース部30は、制御部40を有している。制御部40は、回路基板41を有している。回路基板41には、例えば、図示しないプログラマブルロジックコントローラ(PLC)等の外部制御機器からの電力が供給される。回路基板41は、マニホールドブロック31に内蔵されている。回路基板41は、第1パイロット電磁弁50及び第2パイロット電磁弁60それぞれの駆動を制御する。
第1パイロット電磁弁50は、第1ソレノイド部51を有している。第1パイロット電磁弁50は、第1パイロット圧作用室22に対してパイロット流体を給排する。第1パイロット電磁弁50は、回路基板41から第1ソレノイド部51への電圧の印加が行われると、図示しない流体供給源から供給される圧縮された流体を、第1パイロット圧作用室22へパイロット流体として供給する。一方、第1パイロット電磁弁50は、回路基板41から第1ソレノイド部51への電圧の印加が停止されると、流体供給源から供給される圧縮された流体の、第1パイロット圧作用室22への供給を停止する。そして、第1パイロット電磁弁50は、第1パイロット圧作用室22内のパイロット流体を大気へ排出する。
第2パイロット電磁弁60は、第2ソレノイド部61を有している。第2パイロット電磁弁60は、第2パイロット圧作用室24に対してパイロット流体を給排する。第2パイロット電磁弁60は、回路基板41から第2ソレノイド部61への電圧の印加が行われると、流体供給源から供給される圧縮された流体を、第2パイロット圧作用室24へパイロット流体として供給する。一方、第2パイロット電磁弁60は、回路基板41から第2ソレノイド部61への電圧の印加が停止されると、流体供給源から供給される圧縮された流体の、第2パイロット圧作用室24への供給を停止する。そして、第2パイロット電磁弁60は、第2パイロット圧作用室24内のパイロット流体を大気へ排出する。
スプール弁18は、第1位置と、第2位置と、に切り換え可能である。例えば、回路基板41から第1ソレノイド部51への電圧の印加が行われているとともに、回路基板41から第2ソレノイド部61への電圧の印加が停止されているとする。すると、第1パイロット電磁弁50によって、流体供給源から供給される圧縮された流体が第1パイロット圧作用室22にパイロット流体として供給される。一方で、第2パイロット電磁弁60によって、第2パイロット圧作用室24内のパイロット流体が大気へ排出される。これにより、スプール弁18が第2ピストン収容凹部23に向けて移動する。その結果、スプール弁18は、供給ポートPと第1出力ポートAとを連通し、且つ第2出力ポートBと第2排出ポートR2とを連通する第1位置に切り換わる。スプール弁18が第1位置に切り換わると、供給ポートPと第2出力ポートBとの間が遮断されるとともに、第1出力ポートAと第1排出ポートR1との間が遮断される。

第1パイロット電磁弁50は、第1筒状部53を有している。第1筒状部53は、2つの第1導電部材52を囲繞している。具体的には、第1筒状部53は、2つの第1導電部材52における第1ソレノイド部51とは反対側の端部である先端部を囲繞している。第1筒状部53は、円筒状である。各第1導電部材52の先端は、第1筒状部53の開口を介して第1筒状部53の外へ突出している。第1筒状部53の軸方向は、各第1導電部材52の先端部の延在方向と同じである。第1パイロット電磁弁50は、第1筒状部53の開口がベース部30に向かって開口するようにベース部30に対して配置されている。したがって、各第1導電部材52の先端部は、ベース部30に向かって延びている。
第2パイロット電磁弁60は、第2導電部材62を有している。第2導電部材62は、第2ソレノイド部61に電気的に接続されている。第2パイロット電磁弁60は、第2導電部材62を2つ有している。2つの第2導電部材62の一方は、正極ラインを構成するとともに、2つの第2導電部材62の他方は、負極ラインを構成している。各第2導電部材62は、例えば、柱状である。
第2パイロット電磁弁60は、第2筒状部63を有している。第2筒状部63は、2つの第2導電部材62を囲繞している。具体的には、第2筒状部63は、2つの第2導電部材62における第2ソレノイド部61とは反対側の端部である先端部を囲繞している。第2筒状部63は、円筒状である。各第2導電部材62の先端は、第2筒状部63の開口を介して第2筒状部63の外へ突出している。第2筒状部63の軸方向は、各第2導電部材62の先端部の延在方向と同じである。第2パイロット電磁弁60は、第2筒状部63の開口がベース部30に向かって開口するようにベース部30に対して配置されている。したがって、各第2導電部材62の先端部は、ベース部30に向かって延びている。
第2筒状部63の外周面には、第2装着溝63aが形成されている。第2装着溝63aは、環状である。第2装着溝63aには、第2リップパッキン64が装着されている。第2リップパッキン64は、ゴム製である。第2リップパッキン64は、円環状である。

図2及び図5に示すように、ベース部30は、取付壁部42を有している。取付壁部42には、コネクタ部材70が取り付けられている。取付壁部42は、第1パイロット電磁弁50及び第2パイロット電磁弁60に対向している。取付壁部42は、外面42aと、内面42bと、を有している。取付壁部42の外面42aは、第1パイロット電磁弁50及び第2パイロット電磁弁60に対向する面である。取付壁部42の内面42bは、外面42aとは反対側の面であって、コネクタ部材70が取り付けられる面である。
図2に示すように、ベース部30は、第1接続口43を有している。第1接続口43は、取付壁部42を貫通している。第1接続口43の内側には、第1端子収容部81が配置される。したがって、第1接続口43の内側には、第1コネクタ部80が配置される。第1接続口43には、第1筒状部53が挿入されている。このとき、第1筒状部53の内側には、第1端子収容部81が挿入されている。したがって、第1パイロット電磁弁50は、第1コネクタ部80が内側に挿入される第1筒状部53を有している。第1筒状部53の外周面と第1接続口43の内周面との間には、第1リップパッキン54が設けられている。第1リップパッキン54は、第1筒状部53と第1接続口43との間をシールする。
ベース部30は、第2接続口44を有している。第2接続口44は、取付壁部42を貫通している。第2接続口44の内側には、第2端子収容部91が配置される。したがって、第2接続口44の内側には、第2コネクタ部90が配置される。第2接続口44には、第2筒状部63が挿入されている。このとき、第2筒状部63の内側には、第2端子収容部91が挿入されている。したがって、第2パイロット電磁弁60は、第2コネクタ部90が内側に挿入される第2筒状部63を有している。第2筒状部63の外周面と第2接続口44の内周面との間には、第2リップパッキン64が設けられている。第2リップパッキン64は、第2筒状部63と第2接続口44との間をシールする。
第1筒状部53が第1接続口43の内側に挿入されると、各第1導電部材52が、第1導電部材挿通孔86を介して第1端子収容室83内に挿入されて、第1接続端子82に挿入接続される。このようにして、各第1導電部材52が第1コネクタ部80に挿入接続される。また、第2筒状部63が第2接続口44の内側に挿入されると、各第2導電部材62が、第2導電部材挿通孔96を介して第2端子収容室93内に挿入されて、第2接続端子92に挿入接続される。このようにして、各第2導電部材62が第2コネクタ部90に挿入接続される。
ベース部30は、突出部45を有している。突出部45は、柱状である。突出部45は、取付壁部42から突出している。図5に示すように、突出部45は、基部71の厚み方向において平面視すると、長四角形状である。突出部45は、突出部45の長手方向に延びる2つの長側面45aと、突出部45の短手方向に延びる2つの短側面45bと、を有している。2つの長側面45aは、互いに平行に延びている。2つの短側面45bは、互いに平行に延びている。2つの短側面45bの一方は、2つの長側面45aの長手方向における第1端同士を接続している。2つの短側面45bの他方は、2つの長側面45aの長手方向における第2端同士を接続している。
ベース部30は、2つの係止突起46を有している。2つの係止突起46は、突出部45の2つの長側面45aからそれぞれ突出している。したがって、2つの長側面45aは、2つの係止突起46がそれぞれ突出する突出部45の2つの側面である。
貫通孔72は、2つの案内面75を有している。2つの案内面75は、2つの係止突起46が貫通孔72の内側に挿入される際に、対応する係止突起46の側面46aにそれぞれ案内される。2つの案内面75は、基部71における取付壁部42に対向する面である第1面711から離間するにつれて互いに接近するように傾斜する傾斜面になっている。
図5及び図6に示すように、貫通孔72の長手方向と突出部45の長手方向とが一致した状態で、2つの係止突起46が貫通孔72の内側に挿入されるように、コネクタ部材70をベース部30に対して配置する。このとき、基部71の厚み方向は、挿入方向Z1に一致している。基部71は、2つの係止突起46が貫通孔72の内側に挿入される際に、挿入方向Z1に対して交差する方向へ弾性変形可能になっている。具体的には、2つの係止突起46が貫通孔72の内側に挿入される際に、基部71における貫通孔72の周囲の部分は、基部71の短手方向W1に弾性変形し易くなっている。
次に、本実施形態の作用について説明する。
第1コネクタ部80及び第2コネクタ部90が基部71に一体化されてなるコネクタ部材70が、ベース部30に取り付けられている。そのため、第1コネクタ部80と第2コネクタ部90との相対位置が予め定められた位置からずれてしまうことが無い。したがって、第1導電部材52及び第2導電部材62が第1コネクタ部80及び第2コネクタ部90のそれぞれに容易に挿入接続される。
上記実施形態では以下の効果を得ることができる。
(1)第1コネクタ部80及び第2コネクタ部90が平板状の基部71に一体化されてなるコネクタ部材70が、ベース部30に取り付けられている。これによれば、第1コネクタ部80と第2コネクタ部90との相対位置が予め定められた位置からずれてしまうことが無い。したがって、第1導電部材52及び第2導電部材62を第1コネクタ部80及び第2コネクタ部90のそれぞれに容易に挿入接続することができる。
