To provide a spoke angle measurement device and a method of determining deviation of a spoke angle measurement device, enabling deviation of an angle of a steering wheel of a vehicle to be highly accurately measured.SOLUTION: A spoke angle measurement device 1 comprises an attachment tool 3 detachably attached to a rim portion 6 and a measurement instrument body 21 attached via the attachment tool 3 to a steering wheel 5. The attachment tool 3 includes a rod-shaped center portion 31 and attachment portions 35 located at both ends of the bar-shaped center portion 31. The measurement instrument body 21 comprises a G sensor unit 205 and a gyro sensor unit 206, and is attached to the center portion 31 in such a way such that a YJ axis regulating a horizontal direction of the center portion 31 is parallel to a YD axis regulating a horizontal direction of the measurement instrument body 21, the measurement instrument body comprises determination means which determines a deviation between the YJ axis and the YD axis based on a determination value of the G sensor unit 205 when the YJ axis is parallel to the horizontal surface and a pre-set reference value.SELECTED DRAWING: Figure 1

    【課題】車両のステアリングホイールの角度のずれを高精度で測定可能なスポーク角測定装置、及び、スポーク角測定装置のずれ判定方法を提供する。【解決手段】スポーク角測定装置1は、リム部6に脱着可能に取り付けられる取付治具3と、取付治具3を介してステアリングホイール5に取り付けられる測定器本体21と、を備え、取付治具3は、棒状の中央部31と、中央部31の両端に位置する取付部35と、を有し、測定器本体21は、Gセンサユニット205、及び、ジャイロセンサユニット206を備え、中央部31の水平方向を規定するYJ軸と、測定器本体21の水平方向を規定するYD軸とが平行となるように、中央部31に取り付けられ、YJ軸が水平面に平行な状態におけるGセンサユニット205の検出値と、予め設定された基準値とに基づいて、YJ軸とYD軸とのずれを判定するずれ判定手段を備える。【選択図】図1
