PROBLEM TO BE SOLVED: To constitute a temple connecting structure utilizing the restitutive force of an elastic spring member with simplicity, thereby improving the assembly work thereof, reducing the cost of manufacture and preventing an enormous increase in the size of a wraparound endpiece in order to build the spring member therein. SOLUTION: Connecting pieces 2 and 3 projectingly disposed at the top and bottom of the wraparound endpiece 1 are provided with introducing grooves 4 and 5 and further the deep portions of the introducing grooves are provided with shaft holes 6 and 7. Circular shafts 10 and 11 disposed in a coupling 9 at the top end of the temple 8 are inserted into the shaft holes 6 and 7 through the introducing grooves 4 and 5. At this time, the coupling 9 thrusts the elastic spring 12 integrated with the wraparound endpiece 1 disposed at the wraparound endpiece 1 and the dislodging and shaking of the temple 8 are prevented by the restitutive force of the spring 12.
