Abstract
A reference setting tool for measuring a shape of a side face spline is used to measure the shape of driven teeth that are formed on an axial end face of a vehicle hub unit and that are meshed with drive teeth of a constant velocity joint. The reference setting tool includes: reference teeth that are formed so as to be aligned along a circular ring and so as to have the same shape as the drive teeth of the constant velocity joint; and a reference surface that has a predetermined correlation with the reference teeth, and that is used to set a reference position for measuring the shape of the driven teeth with the reference teeth in mesh with the driven teeth.
