The utility model aims to provide a heat insulation plate structure of an exhaust sensor, which can restrain the influence of radiant heat on the exhaust sensor when a vehicle stops and can cool the exhaust sensor when the vehicle runs. In order to solve the problem, the heat insulation plate structure of the exhaust gas sensor is provided with a heat insulation plate for blocking heat from an exhaust system at a mounting part of the exhaust gas sensor mounted on an exhaust pipe of a vehicle, and the heat insulation plate is provided with a wall part surrounding the exhaust gas sensor in the circumferential direction. The height of the wall portion has a structure such that the upstream side is lower than the downstream side in the flow direction of traveling wind blown to the exhaust sensor when the vehicle is traveling. 本实用新型所要解决的问题在于，提供一种排气传感器的隔热板结构，其可以在车辆停止时抑制辐射热对于排气传感器的影响，并且可以在车辆行驶时使排气传感器冷却。为了解决上述问题，排气传感器的隔热板结构，在安装至车辆的排气管上的排气传感器的安装部，设有阻隔来自排气系统的热的隔热板，隔热板具有在周向方向包围排气传感器的壁部，壁部的高度具有在车辆行驶时吹至排气传感器的行驶风的流向的上游侧低于下
