To achieve a structure of a rack pinion type steering gear unit which can suppress axial direction backlash of a rack bush without deteriorating assembly workability.SOLUTION: A rack stopper 20 is internally fitted into a middle diameter hole section 29 provided in a rack storage section 23, and a side face on an axial direction one side is abutted on a step face 31. A rack bush 19 is internally fitted into a small diameter hole section 30 arranged on a depth side of the middle diameter hole section 29, and an engaging flange section 40 provided on an outer peripheral surface is engaged with an engaging recess 32 provided in an axial direction part of an inner peripheral surface of the small diameter hole section 30. A preload applying member 21 made of an elastic material is arranged between the rack bush 19 and the rack stopper 20 so as to apply axial direction preload to the rack bush 19.SELECTED DRAWING: Figure 7

    【課題】組立作業性を低下させることなく、ラックブッシュの軸方向のがたつきを抑制できる、ラックピニオン式ステアリングギヤユニットの構造を実現する。【解決手段】ラックストッパ20を、ラック収容部23に備えられた中径孔部29に内嵌し、軸方向一方側の側面を段差面31に突き当てる。ラックブッシュ19を、中径孔部29よりも奥側に配置された小径孔部30に内嵌し、外周面に備えられた係合鍔部40を、小径孔部30の内周面の軸方向一部に備えられた係合凹部32に係合させる。ラックブッシュ19とラックストッパ20との間に、ラックブッシュ19に対して軸方向の予圧を付与する弾性材製の予圧付与部材21を配置する。【選択図】図7
