- 繰り出し機構を有するレンズ鏡筒において、
カム溝を有し、円周溝を周面に有する第1の枠部材と、
カムフォロワを有し、該カムフォロワが上記カム溝に嵌入して回動方向及び光軸方向に移動可能な第2の枠部材と、
上記カムフォロワと係合して上記第2の枠部材を相対的に光軸方向に移動可能とさせる直進溝を有し、上記第1の枠部材に対して一体的に回動すると共に、上記円周溝に嵌入して上記第2の部材に対して光軸方向に相対移動しないようにする同一円周上に並べられた一対の突部を有し、該一対の突部が、上記直進溝を挟むように配置され、さらに外力が上記カムフォロワを介して上記カム溝に作用するとき、該一対の突起に均等に反力が生じるようにして上記カム溝にかかる曲げモーメントが抑制されるように配置された第3の枠部材と、
