PROBLEM TO BE SOLVED: To realize high efficiency of assembling work for parts shaped in symmetrical. SOLUTION: The precision component 1 is formed by assembling a plurality of members in an enclosure case 2, and fitting a lid member 3 to the enclosure case 2. In the precision component 1 formed of the enclosure case 2, the lid member 3, a coiled spring 4, a ring-like member 5, a columnar member 6, a first curved member 7 and a second curved member 8, a first position specifying mark 31 and a second position specifying mark 32 are provided in corresponding designated positions of the lid member 3 and the enclosure case 2 in the interior thereof.
