Abstract
A turbocharger includes a wastegate and a turbine housing having a wastegate port. A valve member of the wastegate includes a recess, which defines a gas receiving chamber, into which exhaust gas that has passed through the wastegate port flows when the wastegate port is closed. The inner wall surface of the recess has a guide sidewall located on the outer side of the wastegate port when the wastegate port is closed by the valve member. The guide sidewall includes an inclined surface, which is inclined to approach the center of the gas receiving chamber toward the inlet of the gas receiving chamber.
