PROBLEM TO BE SOLVED: To provide a housing structure which is easy in the processing of an engagement portion between split housings, and can relatively rotate the housings around an axial core of an axis member at assembling, and a steering device having the housing structure.SOLUTION: A housing structure comprises a rack shaft, and a first housing 2 and a second housing 3 which accommodate a driven pulley 16 arranged coaxially with the rack shaft and a drive pulley 14, and are combined to each other at mating faces 4, 5 which are non-parallel with an axial core O of the rack shaft. The first housing 2 has a first guide part 6 which protrudes from the mating face 4 of the first housing 2, the second housing 3 has a second guide part 7 which is engaged with the first guide part 6, and the first guide part 6 and the second guide part 7 are engaged with each other in a circumferential direction of the axial core O, and guide the relative rotation of the first housing 2 and the second housing 3 around the axial core O.SELECTED DRAWING: Figure 2
【課題】分割されたハウジング同士の係合箇所の加工が容易であり、組み付けの際にハウジング同士を軸部材の軸心回りに相対回転可能なハウジング構造およびこれを有する操舵装置を提供する。【解決手段】ラック軸と、ラック軸と同軸に設けられた従動プーリ16と、駆動プーリ14とを収容し、ラック軸の軸心Oと非平行な合わせ面4,5同士で組み合わされる第1ハウジング2と第2ハウジング3とを備え、第1ハウジング2は、第1ハウジング2の合わせ面4よりも突出する第1ガイド部6を有し、第2ハウジング3は、第1ガイド部6に係合する第2ガイド部7を有し、第1ガイド部6と第2ガイド部7とは、軸心Oの円周方向に沿って係合し、第1ハウジング2と第2ハウジング3との軸心O回りの相対回転をガイドする。【選択図】図2
