<p>PURPOSE:To carry out location and fixation without being influenced by shrinkage of an adhesive, by making a circular protrusion part on one of two constructional elements of precision structure having finished location, and a channel part on the other, engaging them each other, applying an adhesive to them. CONSTITUTION:In fixing two constructional elements of a precision structure having finished location with an adhesive, the circular protrusion part 11A is set on one of the constructional elements in such a way that it has a point of one object of the location as the center, and the circular channel part 12A having a point of the other object of the location as the center and a width sufficiently wider than that of the protrusion part 11A is made on the other constructional structure, respectively. The protrusion part 11A is engaged with the channel part 12A, an adhesive is applied only parts which are between the channel part 12A and the protrusion part 11A, to which the shrinkage force is applied symmetrically with respect to the points of the objects of the location, and the adhesive is uniformed, to carry out the location and fixation.</p> |
