PROBLEM TO BE SOLVED: To provide a rotation angle detection device for a vehicle having a simple and compact mechanism and excellent mountability, capable of detecting a steering angle accurately in terms of an absolute value.SOLUTION: A rotation angle detection device for a vehicle includes: a rotation transmission part for transmitting rotational motion 1 of both steering shafts at a speed reduction ratio m(>1.0); and at least one rotation angle detection part for converting the rotational motion 2 transmitted from the rotation transmission part into linear motion, and detecting a displacement magnitude of the linear motion in the noncontact state; in which a rotation angle of the steering shafts is detected in terms of an absolute value by detection of the displacement magnitude.SELECTED DRAWING: Figure 3
【課題】簡易でコンパクトな機構で取付け性が良く、操舵角を絶対値で精度良く検出することが可能な車両用回転角検出装置を提供する。【解決手段】両の操舵軸の回転運動1を減速比m(>1.0)で伝達する回転伝達部と、回転伝達部から伝達された回転運動2を直線運動に変換し、直線運動の変位量を非接触で検出する少なくとも1つの回転角検出部とを具備し、変位量の検出により操舵軸の回転角を絶対値で検出する。【選択図】図3
