ムレンズ鏡枠の制動機構。[Scope of Claim for Utility Model Registration] In a one-piece zoom lens frame in which the linear movement of the operating member performs the zooming operation and the rotational movement performs the distance adjustment operation, the zooming frame is rotated by the linear movement of the operating member. The relative sliding of these two frames between the frame and the fixed frame to which it is rotatably fitted provides frictional resistance over the entire area. To! A braking mechanism for a zoom lens frame, characterized in that a moving member is provided.
