The present invention is to provide a lens holding mechanism of a pair of rimless spectacles whereby the lenses can be securely held in check without an intricate structure therefore. According to this mechanism, a concave portion is notched on the side surface of the lens while a joint member, on the surface of which a groove capable of being fitted into said concave portion is formed, is provided on a proximal end portion with regard to the lens of an endpiece to pivotally and foldably support a temple or both ends of a bridge to connect a pair of lenses juxtaposed to each other. In order to prevent this joint member from slipping out of the concave portion of the lens, basically, a recess portion is provided on the groove of the joint member while a protrusive portion to fit into said recess is provided on the concave portion of the lens. Thereby, it becomes possible to securely hold the lenses in check with the endpiece or the bridge by means of an extremely simple structure.
