Abstract
A turbocharger includes a drive shaft to transmit a driving force of an actuator to a mechanism in the turbo housing, and a bush to rotatably support the drive shaft, wherein a seal is provided at an end portion on the open-air side of the bush. The seal includes a seal body made of resin and a metallic spring fitted into a recessed portion of the seal body, wherein an internal lip portion of the seal body is pressed by the elastic force of the spring to the outer circumferential surface of the drive shaft. Further, an end surface that is contactable with a member (drive link) disposed on the open-air side of the drive shaft is formed in the seal body. The seal having the above-described structure is provided at the end portion on the open-air side of the bush so as to achieve excellent sealability, so that this securely prevents exhaust gas in the turbo housing from passing through between the outer circumferential surface of the drive shaft and the inner circumferential surface of the bush and flowing out to the outside.
