車載用ガス検知装置。[Claims for Utility Model Registration] An on-vehicle gas detection device consisting of a gas sensor whose electrical characteristics change due to adhesion of gas, and a case having a passage through which gas flows and housing the gas sensor in the middle of the passage. The gas passage is bent in a crank shape in the vertical direction so that the middle part is higher than the inlet and outlet, and the gas sensor is disposed in the raised part. 1. An on-vehicle gas detection device, characterized in that it is provided with a flow rate limiting section that limits the flow rate of gas passing through the gas sensor to a certain very low rate.
