To provide a turbocharger capable of easily securing press-fitting allowance and reducing deterioration due to vibration.SOLUTION: A turbocharger comprises: a turbine shaft 14 with a turbine wheel fixed at one end, and rotatably supported; and an impeller 16 pressed into the other end E2 of the turbine shaft 14. The impeller 16 comprises a first press-fitting part 23 and a second press-fitting part 24 separated in an axial direction of the turbine shaft 14 in a through hole 21 through which the turbine shaft 14 passes, where the center of gravity of the turbine shaft 14 in the axial direction is located between the first press-fitting part 23 and the second press-fitting part 24.SELECTED DRAWING: Figure 2 【課題】圧入代を担保しやすくできるとともに振動による劣化を低減することができるターボチャージャーを提供する。【解決手段】ターボチャージャーは、一端にタービンホイールが固定され、回転可能に支持されたタービンシャフト１４と、タービンシャフト１４の他端Ｅ２に圧入されたインペラ１６と、を備える。インペラ１６は、タービンシャフト１４が通る部位である貫通孔２１においてタービンシャフト１４の軸方向に離間した第１圧入部２３と第２圧入部２４を備え、タービンシャフト１４の軸方向における重心が第１圧入部２３と第２圧入部２４との間に位置する。【選択図】図２
