To provide a structure of a rack and pinion type steering device that can improve work efficiency in assembly work.SOLUTION: A rack shaft 11 is configured to have an assist-side rack part 35 having a non-circular cross section outline shape in which an assist-side rack tooth 32 that engages with an assist-side pinion shaft is formed. An engagement hole part 22 having a non-circular outline shape, through which the assist-side rack part 35 can be inserted in an axial direction and through which the assist-side rack part 35 cannot be rotated around a central axis of the rack shaft 11, is arranged at a portion of a rack storage part 14 that stores the rack shaft 11.SELECTED DRAWING: Figure 5 【課題】組立作業の作業効率の向上を図れる、ラックアンドピニオン式ステアリング装置の構造を実現する。【解決手段】ラック軸１１を、アシスト側ピニオン軸と噛合するアシスト側ラック歯３２が形成された非円形の断面輪郭形状を有するアシスト側ラック部３５を有するものとする。ラック軸１１を収容するラック収容部１４の一部に、アシスト側ラック部３５の軸方向の挿通が可能で、かつ、ラック軸１１の中心軸回りのアシスト側ラック部３５の回転を不能とする、輪郭形状が非円形の係合孔部２２を設ける。【選択図】図５
