Abstract
A throttle valve opening sensor for detecting an opening and a specific opening of a throttle valve, comprising a substrate having a partially sectoral printed pattern formed by an opening detecting portion and a specific opening detecting portion for the throttle valve, a rotor adapted to be rotated in association with rotation of the throttle valve, a housing for rotatably supporting the rotor and having a substrate receiving hole for receiving the substrate, a packing installed in the housing for sealing the substrate, a cover mounted on the outside of the packing for fixing the substrate through the packing to the housing, first and second contacts mounted on the rotor and adapted to slide on the opening detecting portion and the specific opening detecting portion, a plurality of terminals installed in the housing and connected to lead wires for power supply and signal output, and a plurality of conductive elastic members for electrically connecting the terminals to the opening detecting portion and the specific opening detecting portion and biasing the substrate against an inner peripheral point of the substrate receiving hole on the opposite side of the terminals, wherein the center of the printed pattern is positioned on the basis of the inner peripheral point so as to coincide with the center of rotation of the rotor.
