Abstract
An elastic memberpositioned between an inner surface of a casingand a front face of a pressure sensing portionof a pressure sensorreduces a possibility of liquid and foreign matters in a tire directly reaching the pressure sensing portion. The elastic member also increases adhesiveness between the pressure sensing portionof the pressure sensorand a labyrinth structure and further prevents a potting agentfrom flowing into the sensing portion. Moreover, the elastic memberis a member constituting at least a part of the labyrinth structure, so that it does not need that a wall is provided on the pressure sensorand a dedicated seal member is provided on the pressure sensing portion
