Objective lens driving device

摘要

In an objective lens driving device having a movable portion including an objective lens held by a lens holder, a damage prevention system for preventing the objective lens or a disk from being damaged when the objective lens or the lens holder collides with the disk is provided. The damage prevention system is constituted by inserting a protecting member formed of an elastic member in a fitting portion on an upper surface of the lens holder while being deformed. In this manner, it is possible to generate a sufficient holding power with respect to the protecting member without using glue or the like.
