ある。[0009] A nickel-titanium alloy having a composition of 51.0 at% nickel and 49.0 at% titanium is formed by pressing into a shape of the temple base 1 and then subjected to an aging treatment at 280 ° C for 1 hour to obtain superelastic properties. Give. In the present embodiment, the shape of the pressed temple base 1 is the hinge piece 11 at the abutment side.
The area connected thereto is a thin portion 12 (a narrowest portion of about 0.9 mm) by a predetermined length, and the range connected to the thin portion 12 is a thick portion 13 (a widest portion of 1.4 mm).
A front and rear portion) is formed, and a metal core portion 14 is formed in a rear area of the thick portion 13 so as to be able to be inserted in a modern manner described later.

Except for the thin region portion 12, the portion is heated to a high temperature from the thick region portion 13 to the cored portion 14, and then cooled. More specifically, in the present embodiment, a high-frequency induction heater (Model HF-3.
Using 5W-3DG), the thick portion 13 and the cored portion 14 are heated at a temperature of 700 to 730 ° C. for 4 to 5 seconds, and then cooled in the atmosphere. Thereby, the temple base 1
In this case, the portion from the thick region portion 13 to the metal core portion 14 is locally annealed, and only the portions 13 and 14 lose superelastic properties.

Is easy. For this reason, the spectacle frame using the temple T of the present embodiment has a thin region portion 12
Although the super-elastic property is sufficient, the thick portion 13 and the modern portion can be easily deformed even in a retail store, so that it is possible to fit the purchaser's mind. Incidentally, the thin region portion 12 is a thin region exhibiting superelastic properties as described in the claims, and the thick region portion 13 is a thick region which can be easily adjusted by bending deformation.
