Abstract

A detachable sunglass unit for detachably attaching sunglasses to eyeglasses, includes two sunglass lenses, two sunglass frames for holding the sunglass lenses, a pivoting device provided between the sunglass frames, a sunglass connecting member extending from the pivoting device, and an eyeglass connecting member provided on the center of the eyeglasses and engaging with the sunglass connecting member. The connecting members use permanent magnets to keep the engaged state. The pivoting device includes an elastic connecting rod, and a pipe member that surrounds the connecting rod. The connecting rod includes end portions that are fixed to sunglass frames, and a bent portion between the end portions. The bent portion is inserted into the pipe member, and the internal diameter of the pipe member is smaller than the width of the bent portion, so that the bent portion is elastically deformed in the pipe member.
