PURPOSE: To make the structure of an assembly compact by putting an adjusting stud through a clearance between both elements equipped with an elastic means, and providing a rod so that the elastic means can be preliminarily extended. CONSTITUTION: Rigid base boards 35 and 36 include mirrors 16 and 17 whose positions can be relatively adjusted to them, and the mirrors 16 and 17 are connected through elastic means 50 and 51 in the configuration of rubber-shaped materials with the base boards 35 and 36. This assembly is provided with adjusting means 52 and 54 in the configuration of a stud, and they can be displaced in an axial direction in one of relatively displaceable two elements, and one edge is brought into contact with the other element, and a load is generated in the elastic means. Then, the adjusting studs 52 and 54 are put through a clearance between the both elements equipped with the elastic means, and a rod is set so that the elastic means 50 and 51 can be preliminarily extended. Thus, the assembly can be made compact, and the shape of the constituting element can be simplified. |
