In order to reduce the effect on a stroke sensor 13 of heat from this turbocharger 1, a heat shield 20 is disposed at a position between the stroke sensor 13 and a center housing 4 of the turbocharger 1, and the heat shield 20 is provided with a plate-shaped cooling water circuit 30 to which cooling water is supplied. Afin de diminuer l'effet sur un capteur de course 13 captant la chaleur émanant d'un turbocompresseur 1, un écran thermique 20 est disposé à une position entre le capteur de course 13 et un logement central 4 du turbocompresseur 1, et l'écran thermique 20 est pourvu d'un circuit d'eau de refroidissement en forme de plaque 30 vers lequel est acheminée l'eau de refroidissement. ストロークセンサ１３に対するターボ過給機１からの熱の影響を軽減するため、ターボ過給機１のセンタハウジング４とストロークセンサ１３との間となる部位に遮熱部２０を配設し、遮熱部２０に冷却水が供給される板状の冷却水路３０が設けてある。
