Zusammenfassung:To provide a lens device miniaturized with an impact preventive part preventing an impact of a member holding a lens being provided in a saved space.SOLUTION: A lens device of the present invention comprises: a first movement member holding an optical element, and moving in an optical axis direction; a first shaft member engaging with a first guidance part of the first movement member to guide movement in the optical axis direction; a base member holding one end of the first shaft member; and a holding member holding the other end of the first shaft member. The base member is provided with: an object side restriction end restricting the first movement member from moving toward an object side; and an image side restriction end restricting the first movement member from moving toward an image side.SELECTED DRAWING: Figure 1 【課題】 本発明は、レンズを保持する部材の衝突を防止する衝突防止部を小スペースで設ける事で小型のレンズ装置を提供することを目的とする。【解決手段】 本発明のレンズ装置は、光学素子を保持し、光軸方向に移動する第1移動部材と、前記第1移動部材の第1案内部と係合し光軸方向の移動を案内する第1軸部材と、前記第1軸部材の一方の端部を保持するベース部材と、前記第1軸部材の他方の端部を保持する保持部材を備えるレンズ装置であって、前記ベース部材には、前記第1移動部材が物体側に向かう方向の移動を規制する物体側規制端および、前記第1移動部材が像側に向かう方向の移動を規制する像側規制端が設けられていることを特徴とする。【選択図】 図1
