PROBLEM TO BE SOLVED: To provide a steering gear which enables an axial dimension of a bush to be set largely in a limited axial space within a housing to stably hold a rack shaft.SOLUTION: A steering gear includes: a pinion shaft; a rack shaft 6; a rack end 7 formed at an end part of the rach shaft 6; a housing 9 housing the rack shaft 6; and a bush 10 which pivotally supports the rack shaft 6 so that the rack shaft 6 may slide relative to the housing 9. The bush 10 includes: a cylindrical elastic member 11 having a slide part 13 which slides on an outer peripheral surface 6B of the rack shaft 6; and a collar 12 molded by a material having rigidity higher than that of the elastic member 11 and fitted on the elastic member 11. One end part of the elastic member 11 protrudes to the rack end 7 side further than one end part of the collar 12 so as to elastically deform when butted with the rack end 7.SELECTED DRAWING: Figure 2

    【課題】ハウジング内部の限られた軸方向スペースにおいてブッシュの軸方向寸法を大きく取ることにより、ラック軸を安定して保持する。【解決手段】ピニオン軸と、ラック軸6と、ラック軸6の端部に形成されたラックエンド7と、ラック軸6を収容するハウジング9と、ハウジング9に対しラック軸6を摺動自在に支承するブッシュ10と、を備える操舵装置であって、ブッシュ10は、ラック軸6の外周面6Bに摺接する摺接部13を有した筒状の弾性部材11と、弾性部材11よりも高剛性の材料で成形され、弾性部材11に外嵌されるカラー12と、を備え、弾性部材11の一端部は、ラックエンド7と突き当たったときに弾性変形するように、カラー12の一端部よりもラックエンド7側に突出している。【選択図】図2
