Linear driving apparatus using vibration wave motor and optical apparatus
Abstract:
In a linear driving apparatus including a vibration wave motor, a driving target body movable in a moving direction, a transmission member which is held by the driving target body and abuts against an abutment part of a moving member to synchronously move the vibration wave motor and the driving target body, and a biasing member which gives a biasing force between the transmission member and the abutment part, the direction of a pressure contact force which a vibrator receives from a friction member and the direction of a biasing contact force which the abutment part receives from the biasing member are parallel and opposite to each other, and the load center of the distribution load of the biasing contact force falls within the range of the vibrator.
