Abstract
A vibration reduction device includes a vibration reduction optical system which reduces vibration by its movement, a fixing portion which assumes a fixing state for fixing the vibration reduction optical system and a releasing state for releasing the vibration reduction optical system, a holding portion for holding/canceling the fixing state of the fixing portion, and a biasing portion for biasing the fixing portion from the fixing state in which the vibration reduction optical system is fixed to the releasing state in which the vibration reduction optical system is released. The biasing portion is interlocked with a releasing operation of the holding portion to release the vibration reduction optical system.
