1. A vehicular exterior rearview mirror assembly, the vehicular exterior rearview mirror assembly comprising:
a mirror head accommodating a mirror reflective element;
a support structure having an inboard end and an outboard end, wherein the inboard end of the support structure is configured for attachment at a side of a vehicle equipped with the vehicular exterior rearview mirror assembly, and wherein the support structure, with the inboard end of the support structure attached at the side of the vehicle, extends laterally from the side of the vehicle;
wherein the mirror head is movably mounted at the support structure;
an adjustment mechanism comprising an electrically operable motor, wherein, with the inboard end of the support structure attached at the side of the vehicle and when the electrically operable motor is electrically operated, the adjustment mechanism operates to move the mirror head along the support structure between a retracted position, where the mirror head is closer to the side of the vehicle at which the support structure is attached, and an extended position, where the mirror head is further from the side of the vehicle at which the support structure is attached;
a shutoff device disposed at the mirror head, wherein the shutoff device comprises a base portion and a movable portion movably disposed at the base portion, and wherein the movable portion has an inner end disposed within the base portion and an outer end opposite the inner end;
wherein, with the adjustment mechanism operating to move the mirror head along the support structure, the movable portion moves relative to the base portion;
wherein, with the adjustment mechanism operating to move the mirror head along the support structure toward the retracted position, the shutoff device stops movement of the mirror head responsive to the movable portion engaging a first micro switch at a first end region of the base portion; and
wherein, with the adjustment mechanism operating to move the mirror head along the support structure toward the extended position, the shutoff device stops movement of the mirror head responsive to the movable portion engaging a second micro switch at a second end region of the base portion that is opposite the first end region of the base portion.
