To provide a spoke angle deviation quantity measuring apparatus capable of easily measuring a spoke angle deviation quantity without increasing man-hours.SOLUTION: A spoke angle deviation quantity measuring apparatus 2 comprises first to fourth support units 21 to 24 which support first to fourth tires 11 to 14 rotatably. After a vehicle 3 is moved to a measurement position with a steering wheel 4 at a neutral position, shaft parts 31d of the respective support units 21 to 24 are positioned with a positioning cap 55. If the respective tires 11 to 14 tilt at a toe angle to a front-rear direction, lateral stress is applied to the respective support units 21 to 24 during a forward movement of the vehicle 3, and the respective support units 21 to 24 rotate around the shaft part 31d. Angle sensors 40 detect angles of rotation of the respective support units 21 to 24. A control device 27 calculates a spoke angle deviation quantity on the basis of the detected angles of rotation.SELECTED DRAWING: Figure 6

    【課題】工数を増加することなく容易にスポーク角ずれ量を測定することができるスポーク角ずれ量測定装置を提供する。【解決手段】スポーク角ずれ量測定装置2は、第1〜第4タイヤ11〜14を回転自在に支持する第1〜第4支持ユニット21〜24を備える。ステアリングホイール4を中立位置に位置した状態で、車両3を測定位置まで移動した後、位置決めキャップ55により、各支持ユニット21〜24の軸部31dを位置決めする。各タイヤ11〜14が前後方向に対してトー角で傾斜している場合、車両3を前進させると、各支持ユニット21〜24に横方向への応力が加わり、各支持ユニット21〜24は、軸部31dを中心にして回転する。角度センサ40は、各支持ユニット21〜24の回転角度を検出する。制御装置27は、検出された回転角度に基いて、スポーク角ずれ量を算出する。【選択図】図6
