Summary:PROBLEM TO BE SOLVED: To provide a structure that can readily reduce weight while meeting strength requirement for a housing for a steering gear unit.SOLUTION: A rack housing 10a constitutes a housing 9a produced by casting such as die casting with a light alloy such as an aluminum-based alloy. A thick part 24 of which radial wall thickness is thicker than surrounding part is partially provided within an axial range X held between an axial center position O of the rack housing 10a and a position where one axial end edge of a bushing support part 16 is present.SELECTED DRAWING: Figure 1 【課題】ステアリングギヤユニット用ハウジングに関して、強度要求に応えつつ、軽量化を図り易い構造を実現する。【解決手段】アルミニウム系合金などの軽合金製で、ダイキャストなどの鋳造により造られたハウジング９ａを構成するラックハウジング１０ａのうち、このラックハウジング１０ａの軸方向中央位置Ｏとブッシュ支持部１６の軸方向一端縁が存在する位置との間に挟まれた軸方向範囲Ｘ内に、周囲の部分に比べて径方向の肉厚が大きくなった厚肉部２４を、部分的に設ける。【選択図】図１
