PURPOSE:To improve the water proofness of a terminal portion, reliability of electric contact, etc., by fixing a water-proof type connector used at an electric connection part to a stopper and making up an electric contact member separately from a piston operation regulating member. CONSTITUTION:A water-proof connector 30 having electric connection terminal portions 31 of a terminal member 32 at an opening portion is fixed to a stopper 29. Moreover, at an end of the connector 30, a pair of contact members 34 opened and closed by a spacer 26 are installed fixed to the end of the electric connection terminal portions 31. When the pressure of a hydraulic pressure led in from the pressure lead-in hole of the case 21 installed at the hydraulic line makes a piston 25 move resisting the power of a bias spring 28 and the spacer 26 fixed to the piston 25 get into the contact members 34 which opposingly come into contact such that the contact members 34 open, so that it is possible to turn the current off. |
