Abstract
A manufacture method of a concave disc-shaped structure of bimetal strip, particularly to one that is a coaxial positioning method of the guide hole which having elastic disc-shape structure bimetal strips not affected by external stress, which having a bimetal structure which outer edge will not be damaged and does not affect by stress while inner edge pulling closed to the outer edge, it includes: a bimetal strip, a lug, and an assembling jig, having two displaceable positioning holes, and use the guiding surface to make the two positioning holes gradually turn inside to condense to the combining surface of the lugs, so as to achieve the purpose of accurate positioning and combination.
