An exhaust-gas turbocharger for an internal combustion engine, in particular of a motor vehicle, includes a turbine housing, a bearing housing, a guide vane carrier, a flow passage component which forms a portion of a flow passage in a turbine of the exhaust-gas turbocharger, and guide vanes, which are disposed on the guide vane carrier such that they can pivot in an annular passage formed between the flow passage component and the guide vane carrier. At least one securing bolt secures the guide vane carrier to the bearing housing. The securing bolt extends through the guide vane carrier and into the bearing housing in a plane parallel to the annular passage.

I claim: 1. An exhaust-gas turbocharger, comprising: a turbine including a turbine housing, said turbine having a flow passage formed therein; a flow passage component forming a portion of said flow passage in said turbine; a bearing housing; a guide vane carrier secured to said bearing housing; said flow passage component and said guide vane carrier forming an annular passage between said flow passage component and said guide vane carrier, said annular passage defining an annular passage plane; guide vanes pivotably disposed on said guide vane carrier such that said guide vanes are pivotable in said annular passage formed between said flow passage component and said guide vane carrier; and a securing bolt for securing said guide vane carrier to said bearing housing, said securing bolt extending through said guide vane carrier and into said bearing housing in a plane parallel to the annular passage plane. 2. The exhaust-gas turbocharger according to claim 1, including an axial stop for said guide vane carrier, said axial stop being formed on said bearing housing, and said axial stop determining an axial mounting position for said guide vane carrier. 3. The exhaust-gas turbocharger according to claim 2, wherein: said guide vane carrier has a through-bore formed therein; said bearing housing has a blind hole formed therein; and said through-bore is aligned with said blind hole when said guide vane carrier is in a mounting position with respect to said bearing housing. 4. The exhaust-gas turbocharger according to claim 2, including: a metal heat shield plate; said guide vane carrier having a radial inner surface and having an encircling projection provided at said radial inner surface; said bearing housing and said guide vane carrier defining an axial direction, said metal heat shield plate having a first axial end and a second axial end disposed opposite said first axial end; said first axial end of said metal heat shield plate being supported against said encircling projection on said radial inner surface of said guide vane carrier; said second axial end of said metal heat shield plate being supported against said bearing housing; and said metal heat shield plate being resilient in the axial direction such that, when said guide vane carrier is in a mounting position, said metal heat shield plate applies a force to said guide vane carrier away from said axial stop and toward said annular passage. 5. In combination with an internal combustion engine, an exhaust-gas turbocharger, comprising: a turbine including a turbine housing, said turbine having a flow passage formed therein; a flow passage component forming a portion of said flow passage in said turbine; a bearing housing; a guide vane carrier secured to said bearing housing; said flow passage component and said guide vane carrier forming an annular passage between said flow passage component and said guide vane carrier, said annular passage defining an annular passage plane; guide vanes pivotably disposed on said guide vane carrier such that said guide vanes are pivotable in said annular passage formed between said flow passage component and said guide vane carrier; and a securing bolt for securing said guide vane carrier to said bearing housing, said securing bolt extending through said guide vane carrier and into said bearing housing in a plane parallel to the annular passage plane. 6. In a motor vehicle having an internal combustion engine, an exhaust-gas turbocharger, comprising a turbine including a turbine housing, said turbine having a flow passage formed therein; a flow passage component forming a portion of said flow passage in said turbine; a bearing housing; a guide vane carrier secured to said bearing housing; said flow passage component and said guide vane carrier forming an annular passage between said flow passage component and said guide vane carrier, said annular passage defining an annular passage plane; guide vanes pivotably disposed on said guide vane carrier such that said guide vanes are pivotable in said annular passage formed between said flow passage component and said guide vane carrier; and a securing bolt for securing said guide vane carrier to said bearing housing, said securing bolt extending through said guide vane carrier and into said bearing housing in a plane parallel to the annular passage plane.
