Turbocharger

1. A turbocharger comprising:

a rotating shaft extending along an axis;

a turbine wheel disposed on a first end portion side of the rotating shaft, a plurality of blades being formed at intervals in a circumferential direction on the turbine wheel;

a turbine housing accommodating the turbine wheel;

a scroll flow path formed in the turbine housing, continuing in the circumferential direction on a radially outer side of the turbine wheel, and having gas flowing therethrough that rotates and drives the turbine wheel;

a nozzle flow path that guides the gas radially inwards from the scroll flow path and supplies the gas to the turbine wheel; and

a vane that adjusts the amount of the gas introduced in the nozzle flow path,

wherein the vane includes two end portions and a guide section that guides the gas such that at least part of the flow of the gas flows radially inwards on a trailing edge side of the blade of the turbine wheel,

the guide section is formed in a pressure surface on a side of the vane where the flow of the gas collides,

the guide section has a convex portion rising in a trailing edge portion on a downstream side in a flow direction of the gas,

the convex portion is formed such that a width-direction intermediate portion rises, in a direction away from a surface side opposite to the pressure surface, with respect to both end portions in a width direction on a trailing edge side of the pressure surface, and

the convex curved surface is formed such that a rise dimension of the width-direction intermediate portion gradually increases from an intermediate portion side toward the trailing edge side of the pressure surface.

2. The turbocharger according to claim 1 , wherein the guide section has a concave portion formed in a leading edge portion of the pressure surface on an upstream side in the flow direction and concave to the surface side opposite to the pressure surface.
