A vehicular exterior rearview mirror assembly includes a powerfold actuator and a mirror head. The powerfold actuator includes an electrically-operable motor that rotatably drives a gear that is engaged with an output gear to pivot the housing portion relative to the output gear and a pivot post. The powerfold actuator includes a base portion fixed relative to the pivot post and the mounting arm, a first gear, a housing portion, a lifter element non-rotatably disposed at the base portion, and a spring element that urges the first gear toward the base portion. With the mirror head at the drive position, the spring element acts on the base portion via the output gear and housing portion. During powered pivoting of the housing portion relative to the pivot post, the spring element acts on the base portion via the output gear and not via the housing portion or the lifter element.
