PROBLEM TO BE SOLVED: To measure a grease movement amount between predetermined parts in a lubrication space without using a large-scale measuring device. SOLUTION: The grease movement amount between predetermined parts in the lubrication space is measured without using a large-scale device, by coloring the grease filled into each part of a mouse bottom part A, a track part B, and a boot inner part C of the lubrication space of a constant velocity joint in different colors, by evaluating the color that changes by the mixing ratio of grease colored in different colors with a colorimetric system by making them correspond to samples with changed mixing ratios in advance, and by finding the mixing ratio of the grease existing in the predetermined part to the grease which each of other parts is filled with, from the correlation of the evaluated numerical value and the numerical value of the colorimetric system found in advance.
