PROBLEM TO BE SOLVED: To provide an optimum fitting feeling of a lens body by finely adjusting a position and an angle.SOLUTION: An angle adjusting member having two rotation fulcrums is connected to the lens body that consists of a frame member for supporting a pair of lenses, and a side frame member extending rearward the lenses from the left/right ends thereof. A mounting mechanism of the lens body further includes a position adjusting/holding member stretchably holding the angle adjusting member. The mounting mechanism of the lens body can flexibly adjust the position and angle of the lens body.SELECTED DRAWING: Figure 1【課題】位置及び角度を微細に調整することによりレンズ体の最適なフィット感を得る。【解決手段】一対のレンズを支持する枠部材と、その左右端部からレンズの後方へ延びる側枠部材とから成るレンズ体に２つの回転支点を持つ角度調整部材を連結し、さらに、角度調整部材を伸縮可能に保持する位置調整保持部材と、からなるレンズ体の取付機構であって、レンズ体の位置及び角度をフレキシブルに調節する。【選択図】図１
