1. An oscillating power tool comprising:
a housing;
a motor disposed generally within the housing and including a drive shaft;
an output spindle configured to be driven by the motor and journaled for oscillating rotation about an oscillation axis;
a drive mechanism configured to convert rotation of the drive shaft into oscillating rotation of the output spindle about the oscillation axis, the drive mechanism including an eccentric member configured to rotate off center about a motor axis, and a forked member operatively coupled to the eccentric member and configured for oscillating rotation about the oscillation axis in response to rotation of the eccentric member; and
an amplitude adjustment actuator configured to move the eccentric member in a direction generally parallel to the motor axis to change an angular amplitude of oscillating rotation of the forked member, wherein the amplitude adjustment actuator includes a first actuator portion having a first actuation surface extending through a first aperture in the housing and a second actuator portion having a second actuation surface extending through a second aperture in the housing.
