摘要： A camera assembly includes a motor configured to generate a driving power; a motor shaft that extends from the motor, such as to define a first axis, and is configured to rotate by the driving power of the motor; a pulley configured to rotate on a second axis, that is spaced from the first axis, according to rotation of the motor shaft; a belt configured to couple the motor shaft and the pulley, and convert the rotation of the motor shaft to rotation of the pulley, and tension of the belt applies a force to the motor shaft in a direction towards the second axis; a camera module configured to be mounted on the pulley and rotate together with the pulley; and an elastic body configured to apply a biasing force to the motor shaft such as to bias the motor shaft in a direction away from the second axis.
