Description

Driving apparatus for vehicle The present invention relates to a driving device for a vehicle, and more specifically, to a driving device for a vehicle that adjusts the distance between a mirror housing and a base provided in a vehicle. The vehicle is equipped with an inside mirror to allow the driver to assess the situation behind the vehicle, and outside mirrors on both sides to assess the situation to the sides and rear. Through the field of view obtained by the inside or outside mirrors, the driver can identify surrounding vehicles or pedestrians and perform actions such as reversing, overtaking, and changing lanes. Recently, camera mirrors containing cameras are being applied instead of outside mirrors to reduce air resistance while driving and minimize the risk of damage from external impacts. Since images of the vehicle's surroundings acquired by the camera mirror are displayed through a display device installed inside the vehicle, the driver can easily grasp the situation around the vehicle. Meanwhile, while the outside mirror or camera mirror is extended to allow the driver to perceive the surrounding conditions of the vehicle during driving, it is necessary to fold the outside mirror or camera mirror toward the vehicle when parking or passing through a narrow space to prevent damage to the mirror or to secure the surrounding space. In this case, the driver can rotate the outside mirror or camera mirror using an actuator or manually.
