を特徴とする過給機。 A turbine shaft formed by connecting a turbine rotor housed in a turbine casing and a compressor impeller housed in a compressor casing is supported by a bearing provided in a center housing, and the turbine shaft on the turbine shaft is rotatably supported by a bearing provided in a center housing. A first lubricating oil passage for fitting a seal ring for sealing between the turbine casing and the bearing at a position closer to the casing and for supplying lubricating oil to the bearing, and the first lubricating oil passage. A second lubricant passage formed separately and opened near the seal ring, and a second lubricant passage interposed between the first lubricant passage, the second lubricant passage, and the lubricant supply section for supplying the lubricant. A supercharger characterized in that a supercharger is provided with passage switching means that connects the lubricating oil passage to at least the first lubricating oil passage when the engine is in operation, and connecting only to the second lubricating oil passage when the engine is stopped.
