DRIVING DEVICE, LENS BARREL, AND OPTICAL APPARATUS INCLUDING THE LENS BARREL |
摘要 |
In a driving device, a distance from a guide member to a vibrator is less than that from the guide member to a permanent magnet in a plane perpendicular to a guiding direction of a guide member. An attraction force between the permanent magnet and a magnetic body acts as a force to rotate (i.e., a rotating force) a holding member about an axis of the guide member, and the vibrator is pressed against a contact member by the rotating force. |
