ABSTRACT:
An endpiece (E) is composed by disposing a pair of elastic inner and outer wiring or plating parts in juxtaposition. An outer part external member (1) is adopted to keep a shape and structure of the endpiece (E) intact and reinforced. The inner part is a buffer piece (2) doubled back into a hairpin shape and has at least a first bending portion (21) of convex shape and a second bending portion (22) of concave shape. When a temple (T) is unfolded to excess, the first and second bending portions (21) and (22) flexibly bend towards a direction to which those portions expand so as to counterbalance stress to which the external member (1) is subjected.
