Abstract
A turbocharger includes a turbine housing accommodating a turbine wheel, a bearing housing rotatably supporting a rotating shaft to which the turbine wheel is fixed, a variable geometry mechanism accommodated in the turbine housing, surrounding the turbine wheel, and configured to guide a fluid to the turbine wheel, and a spring member held by the variable geometry mechanism and the bearing housing in an axial direction along the rotating shaft. The variable geometry mechanism has an inner circumferential portion surrounding a through hole in which the turbine wheel or the rotating shaft is disposed, and an outer circumferential portion located between the spring member and the turbine housing. The outer circumferential portion is distanced further away from a rotational axis of the rotating shaft than the inner circumferential portion. The outer circumferential portion includes a first end face contacting the spring member, and a second end face contacting the turbine housing.
