出装置。[Claims for Utility Model Registration] A chamber filled with at least gas, an operating member that is partially inserted into the chamber and moves forward and backward with respect to the chamber, and a pressure that directly or indirectly detects the pressure of the gas. In the apparatus for detecting the forward/backward position of an operating member, the apparatus includes: a detecting means; and an advancing/retracting position calculating means for determining the advancing/retracting position of the operating member with respect to the chamber based on the detected pressure, wherein the pressure of the gas detected by the pressure detecting means temperature detection means for directly or indirectly detecting the temperature within the chamber that affects the temperature; and temperature correction means for temperature-correcting the advance/retreat position of the operating member calculated by the advance/retreat position calculation means based on the detected temperature. A device for detecting forward and backward positions of an operating member, comprising:
