求の範囲第１項に記載の制御弁の開度検出装置。 (3) 弾性体はゴムばねである実用新案登録請求
の範囲第１項に記載の制御弁の開度検出装置。[Scope of Claim for Utility Model Registration] (1) A detection shaft that is interlocked with the valve stem of a valve body of a control valve that is opened and closed to control the operating state of an automobile engine, and that is arranged on the same axis as the valve stem. When the detection shaft is displaced by the valve stem against the spring force of the return spring of the detection shaft, the contact electrical resistance of the brush held in the holder attached to the detection shaft is reduced. In the control valve opening detection device for an automobile engine, which outputs an electric signal corresponding to the opening of the valve body, the detection shaft has a spring force that is relatively larger than the spring force of the return spring. An opening degree detection device for a control valve, characterized in that the device is attached to the holder via an elastic body having an elastic body. (2) The control valve opening detection device according to claim 1, wherein the elastic body is a coil spring. (3) The control valve opening detection device according to claim 1, wherein the elastic body is a rubber spring.
