PURPOSE:To eliminate impact load of a contact as well as to improve durability ever so better, by installing a dashpot, which turns the velocity of a rod moving toward the contact to a low velocity, inside a body, in case of an idle state detector. CONSTITUTION:A rod 4 is installed in a body 2 constituting an adjust screw of a throttle valve free of movement in an axial direction. In time of idling, the rod 4 comes into contact with a contact 5 and detects an idle state. At this time, capacity in a cylinder chamber 14 decreases, and oil in this cylinder chamber 14 flows out to a liquid chamber 13 little by little by way of an orifice 15 so that a piston 3 and the rod 4 move at low velocity by action of a dashpot. Thus, even if the throttle valve is suddenly closed, impact load is in no case added to the contact so that durability is improved. |
