TURBOCHARGER |
| 摘要 |
A turbocharger includes: a bearing portion which is provided in a turbine housing; a shaft rotatably inserted into a bearing hole of the bearing portion; an attaching member fixed to the shaft; and a valve coupled to the shaft via the attaching member and configured to open and close a flow path opened to an internal space along with rotation of the shaft. The attaching member includes: a base portion provided with an insertion hole of the shaft; and an extension portion integrally formed with the base portion and extending from the base portion in a radial direction of the shaft to thereby hold the valve. The base portion is provided at least at a part of a range of the shaft in a circumferential direction of the shaft, and protrudes more in the radial direction of the shaft than the bearing portion. |

1. A turbocharger comprising:
a housing including an internal space formed therein; a cylindrical bearing portion provided in the housing, the cylindrical bearing portion being provided with a bearing hole penetrating between the internal space of the housing and an outside of the housing; a shaft rotatably supported in the bearing hole, at least one end of the shaft protruding more to an inside of the housing than the bearing portion; an attaching member fixed to a side of the one end of the shaft protruding from the bearing portion; and a valve coupled to the shaft via the attaching member, the valve being configured to open and close a flow path opened to the internal space along with rotation of the shaft, wherein the attaching member includes:
a base portion in which an insertion hole through which the shaft is inserted is formed; andan extension portion which is formed integrally with the base portion and which extends from the base portion in a radial direction of the shaft to thereby hold the valve, and the base portion is provided at least at a part of a range of the shaft in a circumferential direction of the shaft, and protrudes more in the radial direction of the shaft than the bearing portion. |
