Abstract
In a linear driving apparatus including a vibration wave motor, a sliding guide method is used as a guiding method for a moving member. The apparatus further includes a driving target body movable in a moving direction, a transmission member configured to engage with the driving target body, abut against the abutment part of the moving member, and transmit the driving force of the vibration wave motor to the driving target body, and a biasing member configured to apply a biasing force between the transmission member and the abutment part. The direction of a frictional contact force that the vibrator receives from the friction member and the direction of a biasing contact force that the abutment part receives from the biasing member are parallel and opposite, and the load center of the distribution load of the biasing contact force exists in the range of the outside shape of the vibrator.
