Patent number: 10583772Abstract: A vehicle lamp includes a lamp body, a lamp unit and a leveling actuator. The lamp unit is supported to the lamp body to be aimable in an upper and lower direction and in a right and left direction. The leveling actuator rotates the lamp unit in the upper and lower direction independently from rotation by the aiming. An aiming nut is mounted to the aiming screw and threadably engaged with the aiming screw. The leveling actuator comprises an actuator main body fixed and supported to the lamp unit and an output shaft member supported to the actuator main body to be moveable in the front and rear direction of the lamp. The output shaft member is disposed to protrude upward or downward from the actuator main body and is coupled to the aiming nut at a leading end portion of the output shaft member.Type: GrantFiled: September 25, 2018Date of Patent: March 10, 2020Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Daisuke Aizawa, Keiichi Tajima
