PROBLEM TO BE SOLVED: To provide a shock absorption mechanism of spectacles with which the shock received by the entire part of the spectacles can be efficiently absorbed by dispersing the concentration of the stresses exerted on members and with which higher wearing safety can be realized.;SOLUTION: An endpiece E is constituted by disposing two elastic wires or plate materials in parallel inside and out, and an outer member 1 bent to a bow shape is disposed for the purpose of form retention and reinforcement on the outer side thereof. In addition, a buffer piece 2 which is turned up to a hairpin shape to form at least a first flexure section 21 of a convex curve type and a second flexure section 22 of a concave curve type on the inner side of the outer member 1. The operation to overexpand the opening of a temple T balances the stresses that the outer member 1 receives by bending of the first flexure section 21 and the second flexure section 22 of the buffer piece in a widening direction, and the inner side energization of the temple T balances the stresses that the outer member 1 receives by bending of the first flexure section 21 and the second flexure section 22 of the buffer piece in a folding contraction direction.;COPYRIGHT: (C)2006,JPO&NCIPI
