Description
軸受台１２は、図２に示されるように、過給機１０の径方向に沿ってハブ側面１４が形成されており、ハブ側面１４は、渦室１１を形成する外側ケーシング内面と滑らかに繋がるようにハブ側面１４のうち半径方向外側の部分が曲面状に形成されている。 As shown in FIG. 2, the bearing stand 12 has a hub side surface 14 formed along the radial direction of the supercharger 10, and the hub side surface 14 is smoothly connected to the inner surface of the outer casing forming the vortex chamber 11. Thus, the radially outer portion of the hub side surface 14 is formed in a curved surface shape.
