According to an embodiment of the present disclosure, provided is a head-up display actuator for a vehicle, comprising: a driver unit including a motor for generating a driving force, a lead screw constituting a driving shaft, and a guide shaft spaced apart from the lead screw and formed in parallel with the same; a link unit coupled to the lead screw and capable of moving in the longitudinal direction of the lead screw; and a cooling unit attached to the motor to cool the motor. Therefore, clearance of a contact part can be prevented, and back lash of the lead screw and clearance or the like of the link unit can be removed.
본 개시의 일 실시예에 의하면, 구동력을 발생시키는 모터(motor), 구동축을 이루는 리드스크류(lead screw), 리드스크류와 이격된 상태로 나란하게 형성되는 가이드축(guide shaft)을 포함하는 구동부(driver unit); 리드스크류와 결합하고, 리드스크류의 길이 방향으로 이동 가능한 링크부(link unit); 및 모터에 부착되어, 모터를 냉각하는 냉각부(cooling unit)를 포함하는 것을 특징으로 하는 차량용 헤드업 디스플레이 액추에이터(Head-Up Display actuator)를 제공한다.
