## Abstract

A glasses-type shutter holder may include left and right temple parts connected respectively to left and right frame end parts of frame. The left and right temple parts may be foldable respectively with respect to the left and right frame end parts in accordance with movement, for each frame end part and temple part pair, of a contact position at which a movement part provided with one of the temple part and the frame end part of the pair is in contact with a contact part of the other of the temple part and the frame end part of the pair. For each of the pairs, the contact part is in contact with the movement part when the temple part is unfolded to a maximum degree, and a maximum degree of opening of the temple part is varied in accordance with the movement of the movable part.
