An electric actuator assembly is proposed. The electric actuator assembly includes: a brush card assembly provided with a brush card part in which a plurality of terminals is molded through insert injection molding; a motor assembly coupled to the brush card assembly and electrically connected thereto; a housing provided with a coupling part into which the brush card assembly is inserted, having a circuit board provided with a connector, and having a gear assembly for receiving power from the motor assembly and transmitting the power to outside, the circuit board and the gear assembly being installed in the housing, wherein terminal holes through which the plurality of terminals passes and a coupling hole into which a part of the brush card part is inserted are separately provided in the coupling part.

A rotor for an electric motor, comprising a rotor magnet and a bearing for the rotatable support on a fixed axle, the bearing comprising first and second bearing half-shells, wherein at least the first bearing half-shell is moveably arranged within the rotor body with respect to the second bearing half-shell, and wherein the first bearing half-shell is supported against the rotor body by a resilient element tangentially arranged with respect to the axle. The resilient element, at both its side surfaces facing in an axial direction of the axle, has at least one respective first protrusion extending in the axial direction, and the first bearing half-shell, on a side facing away from its bearing surface, includes at least two axially spaced second protrusions each extending in a radial direction and cooperating with the first protrusions for aligning the resilient element.

An actuator includes a first damper member and a second damper member that couple a movable body and an immovable body and each include a gel member in a tubular form. The gel member has a first end face and a second end face that are different from each other in cross-sectional shape. The first damper member and the second damper member are oppositely oriented in the axial direction, and are opposite from each other in position of the first end face and the second end face. Consequently, the characteristic variance due to the difference in the direction, in which the movable body moves, is reduced or removed in the actuator as a whole, even if each single damper member is involved with such characteristic variance.
