Abstract
A first turbocharger comprises a first center housing and a first return passage. A second turbocharger comprises a second center housing and a second return passage. The first return passage joins the second return passage at a junction. The length of the second return passage from the second center housing to the junction is longer than that of the first return passage from the first center housing to the junction. A bellows-shaped vibration absorption portion is provided at the second return passage. The first return passage comprises a first upstream return passage and a first downstream return passage, and the first upstream and downstream return passages are connected to each other via the flexible hose.
