以上のように本考案によれば、リザーバ本体の下部には、一端をリザーバ本体 の側部に開放させた収納孔が設けられるとともに、両コネクタの一方が該収納孔 の他端に連なって一体に設けられ、前記収納孔の一端を着脱可能に閉塞する蓋部 材には、収納孔内に収納される支持部が連設され、該支持部で支持されたリード スイッチに連なる一対のリードフレームの先端が、前記一方のコネクタ内に接続 端子として突出されるので、両コネクタの接続・分離作業時にリザーバ本体側に 固定されるコネクタががたつくことはなく、したがって両コネクタの接続・分離 作業時に断線が発生することはない。 As described above, according to the present invention, the lower portion of the reservoir body is provided with the storage hole having one end opened to the side portion of the reservoir body, and one of the connectors is connected to the other end of the storage hole to be integrated. And a pair of lead frames connected to a reed switch supported by the support portion, the support portion being provided in the storage hole and detachably closing one end of the storage hole. Since the tip of the connector protrudes into the one connector as a connection terminal, the connector that is fixed to the reservoir body side does not rattle when connecting or disconnecting both connectors, and therefore disconnection occurs when connecting or disconnecting both connectors. Will never occur.
