PROBLEM TO BE SOLVED: To provide a dishing amount measuring apparatus wherein the dishing amount can be measured over the whole wheel fixing surface, zero-return adjustment is easy, measurement in various diameters is possible, and the number of components is small. SOLUTION: This measuring apparatus consists of a slide bar 6, a slide 7 sliding the slide bar 6, a dial gauge 8 arranged on the slide 7, a dial gauge terminal 9 which is installed to the dial gauge 8 and can freely ascend and descend, a scale 12 formed in the dial gauge 8, and a zero-return bottom 11 returning the scale 12 to zero. After the scale 12 is returned to zero with the zero-return bottom 11, the dial gauge terminal 9 ascends or descends, and the amount of its movement is shown with the scale 12.
