Abstract
A heater and a temperature sensor are mounted to a valve member driven for opening and closing through a piston and a rod, primary conductors extending from the heater and the temperature sensor are connected to a terminal block mounted to the piston, a secondary conductor having a spiral portion for expansion and contraction is connected between the terminal block and a connector mounted to a lid body, and displacements of the primary conductors due to opening and closing of the valve member are absorbed by expansion and contraction of the spiral portion.
