Patent ID: 8922908

Claim:
A lens apparatus comprising: a lens housing; a driven member that is driven in a first direction along an optical axis; a lens barrel body that comprises a lens, is arranged so as to be movable along the optical axis, is separated from the driven member upon receiving an impact of predetermined magnitude including a component of a second direction opposite to the first direction and moves along the optical axis; and a drive member that drives the driven member in the first direction, wherein when the lens housing receives an impact of predetermined magnitude including a component of the first direction, the drive member and the driven member are separated apart, and the driven member and the lens barrel body move together in the first direction, and when the lens housing receives an impact of predetermined magnitude including the component of the second direction, the drive member prevents the driven member from moving in the second direction, the driven member and the lens barrel body are thereby separated apart, and the lens barrel body moves along the optical axis.
