    Abstract: In an eyewear mounting device, a pressing surface portion is formed at an end of a frame, a pair of supporting arms is provided on the pressing surface portion at an interval, a shaft around which a tightening band is wound is provided between tips of the supporting arms. An operating member rotationally attached between the supporting arms has a pressing operation portion, a pulling-up operation portion, an elastic piece and an engaging claw. The engaging claw is engageable with any of a plurality of protruding portions provided in a longitudinal direction of a surface side of the tightening band. This configuration results in easy operation of the operating member in the state where the eyewear mounting device is worn on the face. Further, only one operating member is used as the component member, thus resulting in easy assembly of the eyewear mounting device.
