Title: SEAL STRUCTURE OF TURBOCHARGER
Abstract:
A seal structure of a turbocharger includes a bearing housing, a turbine housing, and a gasket. The turbine housing is coupled with a bearing housing. The gasket is interposed between the bearing housing and the turbine housing. The gasket includes a base material layer, a seal portion, and a heat insulating portion. The seal portion is arranged in a predetermined first radius area on an outer circumferential side of the base material layer. The heat insulating portion is adjacent to a surface of the bearing housing on the exhaust flow path side. The heat insulating portion is arranged in a second radius area of the base material layer. The second radius area is on an inner circumferential side from the first seal portion. The heat insulating portion has a coating layer outside the base material layer. The coating layer is lower in thermal conductivity than the base material layer.
