To provide a vehicular steering device and belt tension adjustment method that make it easy to adjust belt tension.SOLUTION: In a vehicular steering device, a projection 50 is provided on an internal wall surface of a housing 16, the projection being located between a drive pulley 41 and a follower pulley 42 in a radial direction orthogonal to an axial line m1 of a rack shaft 12 and projecting up to a position overlapping the drive pulley 41 in the axial direction of the rack shaft 12. A toothed belt 43 is wound around the drive pulley 41 and the follower pullet 42. An inter-axial distance between the axis m2 of the drive pulley 41 and the axis m1 of the follower pulley 42 is lengthened from the position where the drive pulley 41 abuts on the projection 50. Thereby, a motor 20 is fixed in position so as not to move relative to the housing 16 while the toothed belt 43 has regulated tension.SELECTED DRAWING: Figure 3
【課題】ベルトの張力の調整を実施しやすくすることができる車両用操舵装置及びベルト張力調整方法を提供すること。【解決手段】ハウジング16の内部の壁面には、ラックシャフト12の軸線m1に直交する径方向において駆動プーリ41と従動プーリ42との間に位置し、ラックシャフト12の軸方向において駆動プーリ41と重なる位置まで突出する突出部50が設けられ、駆動プーリ41と従動プーリ42とに歯付きベルト43が巻き掛けられ、駆動プーリ41を突出部50に当接させた状態から駆動プーリ41の軸線m2と従動プーリ42の軸線m1との距離である芯間距離を長くさせることにより歯付きベルト43が規定の張力となった状態で、モータ20がハウジング16に対して相対的に移動できないように固定されている車両用操舵装置。【選択図】図3
