PROBLEM TO BE SOLVED: To obtain a temple pivotal support mechanism, which is capable of pivotally supporting the temples in a structurally stable state without using screws for spectacle front frame parts, are smooth in folding and turning and is extremely simple in assembling and disassembling. SOLUTION: A spectacle front frame part 1 is provided with a bracket end piece 2, having an upper arm and a under arm. The temple 5 bored with a ring hole at a fulcrum end is born in the fork space between pivotally supporting holes 23 and 24 coaxially pierced at the upper arm and the under arm by means of a mallet-shaped pivot 4. A mechanism for biasing the temple fulcrum end with the energizing force of a spring bar 3 and for pivotally supporting this end is adopted.
