Claims (1)
回動摺動とが可能な操作環と、 鏡筒本体と操作環との間に配された摺接手段とを備え、 直進摺動の際、摺接手段は操作環と一体となって鏡筒本
体上を摺動し、摺接手段と鏡筒本体との間で摩擦が発生
し、 回転摺動の際、摺接手段を鏡筒本体と一体となって操作
環が摺接手段上を摺動し、摺接手段と操作環との間で摩
擦が発生することを特徴とする操作環の摩擦発生機構。[Scope of Claim for Utility Model Registration] A lens barrel body, an operating ring capable of sliding linearly in the direction of the optical axis and rotating and sliding around the optical axis, the lens barrel body and the operating ring; and a sliding contact means disposed between the lens barrel body, and during straight sliding, the sliding contact means slides on the lens barrel body integrally with the operation ring, and the sliding contact means and the lens barrel body slide together. Friction is generated, and during rotation and sliding, the sliding contact means is integrated with the lens barrel body and the operating ring slides on the sliding contact means, causing friction between the sliding contact means and the operating ring. A friction generating mechanism for the operating ring characterized by:
