To facilitate assembly operation in a vehicle steering device using a rotation transmission device used in switching between transmission and blocking of rotation.SOLUTION: A vehicle steering device uses a rotation transmission device 1 that is provided with protrusions disposed engageably with each other on a first member and a second member configured to come close to or separate from each other by magnetic force of an electromagnet 10 and is configured to switch between transmission and blocking of rotation between an input shaft 3 and an output shaft 4 by engagement and disengagement between the protrusions. The vehicle steering device includes: a rack 104 with both ends connected to a pair of turning wheels 107; a rack housing 105 housing the rack 104 in a movable manner; and a pinion 110 engageable with the rack 104. A case 2 of the rotation transmission device 1 is attachably and detachably fixed to the rack housing 105. In a state where the case 2 is detached from the rack housing 105, the output shaft 4 is separated from the pinion 110. In a state where the case 2 is attached to the rack housing 105, the output shaft 4 integrally rotates with the pinion 110.SELECTED DRAWING: Figure 2
【課題】回転の伝達と遮断の切り換えに用いられる回転伝達装置を用いた車両用操舵装置において、その組み立て作業を容易にする。【解決手段】電磁石10の磁力によって互いに接近又は離反する第1部材及び第2部材に互いに噛み合う突起を備え、突起同士の噛み合い及び噛み合いの解除によって入力軸3と出力軸4との間での回転の伝達及び遮断の切り替えを行う回転伝達装置1を用い、一対の転舵輪107にその両端が接続されるラック104と、ラック104を移動可能に収容するラックハウジング105と、ラック104に噛み合うピニオン110とを備え、回転伝達装置1のケース2はラックハウジング105に着脱可能に固定され、ケース2をラックハウジング105から取り外した状態では出力軸4がピニオン110から切り離され、ケース2をラックハウジング105に取り付けた状態では、出力軸4がピニオン110と一体に回転する車両用操舵装置とした。【選択図】図2
