ABSTRACT:
A spectacle frame according to the present invention includes a pair of lens hangers each having a lens connector at a distal end thereof, and a pair of fixing barrels for supporting proximal ends of the lens hangers to be rotatable on a leftward/rightward axis, and joined to a brow bar. The fixing barrel has a supporting hole extending leftward/rightward, an outer circumference concentric with the supporting hole, having a predetermined radius of curvature, and an annular groove formed on the outer circumference. The lens hanger which is made of a metallic wire has a shaft portion fit in a rotatable manner into the supporting hole of the fixing barrel, an engagement portion engageable with the annular groove of the fixing barrel, and a spring portion formed between the shaft portion and the engagement portion to elastically bias the engagement portion toward the annular groove.
