Summary:To improve workability in assembling, in an exhaust turbo supercharger in which a waste gate valve is driven by an intake operation-type actuator.SOLUTION: An exhaust turbo supercharger includes a turbine housing, a bearing housing 5, a compressor housing 4, and a bracket 30 for actuator, and a positive pressure intake operation-type actuator 18 is fixed to the bracket 30 for actuator. The bearing housing 5 is integrated with the turbine housing, and the compressor housing 4 is fixed to the bearing housing 5 through the bracket 30 for actuator. The bracket 30 for actuator and the bearing housing 5 are accurately positioned by fitting an engagement projection 34 and an engagement recessed portion 35. Accordingly, a labor hour for assembling the actuator 18 and a waste gate valve while ensuring their positional relationship, can be reduced.SELECTED DRAWING: Figure 6 【課題】ウェイストゲートバルブが吸気作動式のアクチュエータによって駆動される排気ターボ過給機において、組み付けの作業性を向上させる。【解決手段】排気ターボ過給機は、タービンハウジングと軸受ハウジング５とコンプレッサハウジング４と、アクチュエータ用ブラケット３０とを備えており、アクチュエータ用ブラケット３０に正圧吸気作動式のアクチュエータ１８が固定されている。軸受ハウジング５はタービンハウジングに一体化されている一方、アクチュエータ用ブラケット３０を介してコンプレッサハウジング４が軸受ハウジング５に固定されている。アクチュエータ用ブラケット３０と軸受ハウジング５とは、係合突起３４と係合凹所３５との嵌まり合いによって正確に位置決めされている。従って、アクチュエータ１８とウェイストゲートバルブとの位置関係を正確化して組み付けの手間を抑制する。【選択図】図６
