A mirror angle adjusting device can stably hold a pivot plate (H), while a contact part between the pivot plate (H) and an actuator (A) smoothly slides for a long period of time. The mirror angle adjusting device includes the pivot plate (H) attached to a back side of a mirror (M), and the actuator (A) for holding the pivot plate (H) . In the mirror angle adjusting device, grooves (121a) for storing a lubricant are formed on a support surface of the actuator (A), and grooves (311) for storing a lubricant are formed on a sliding surface of the pivot plate (H) which is slidably in contact with the support surface. In the mirror angle adjusting device, the contact part between the pivot plate (H) and the actuator (A) can smoothly slide for a long period of time, and the pivot plate (H) can be stably held.
