PROBLEM TO BE SOLVED: To achieve dimensional measurement of, mainly, an air conditioning case constantly under the same conditions.SOLUTION: Dimensional measurement reference points 61, 62 are formed integrally on an outer surface of an air conditioning case 30. The dimensional measurement reference points 61, 62 are provided to be spaced from each other at least two positions, so that at least either of a parallel reference line 63 or a vertical reference line 64 to an on-vehicle installation reference plane 5 of the air conditioning case 30 can be determined. |
