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
