An elastic member (11) placed between the inner surface of a casing (2) and the front side of a pressure sensing section (8) of a pressure sensor (1) not only reduces possibility of liquid and foreign matters in the tire directly reaching the pressure sensing section (8), but also increases the degree of intimate contact between the pressure sensing section (8) and a labyrinth structure and prevents a potting agent (9b) from entering around into the sensing section (8). Also, because the elastic member (11) is a member forming at least a part of the labyrinth structure, the pressure sensor (1) does not require a wall and the pressure sensing section (8) does not require a dedicated seal member.
La présente invention concerne un élément élastique (11) placé entre la surface interne d'un logement (2) et le côté avant d'une section de captage de pression (8) d'un capteur de pression (1) qui non seulement réduit la possibilité que du liquide et des matières étrangères dans le pneu n'atteignent directement la section de captage de pression (8), mais augmente également le degré de contact intime entre la section de captage de pression (8) et une structure labyrinthique et évite à un agent d'enrobage (9b) d'entrer dans la section de captage (8). De plus, puisque l'élément élastique (11) forme au moins une partie de la structure labyrinthique, le capteur de pression (1) n'exige pas de paroi et la section de captage de pression (8) ne nécessite pas d'élément de scellement dédié.
