An electric actuator includes a motor having a rotary shaft. The electric actuator further includes a vibration damping gasket mounted on the motor. The vibration damping gasket includes an annular body attached around the motor and an end wall formed on one end of the annular body, and the end wall defines a through hole allowing the rotary shaft to pass therethrough. The motor further includes an outer housing, and the annular body of the vibration damping gasket is attached around the outer housing. The end wall of the vibration damping gasket contacts with the end surface of the outer housing. The vibration damping gasket is made from a resilient material. The electric actuator can effectively reduce the mechanical vibration, improve a buffering effect thereof, and hence reduce the noise.

A brush assembly has a brush, a brush cage, and a spring. The spring is a constant force spring having two coil portions and a connecting portion. The connecting portion the brush are together received in the brush cage. The brush has a contact end arranged to make sliding contact with a commutator and a second end remote from the contact end against which the spring applies its force, to urge the brush out of the brush cage. A hook is formed at each of two opposite sides of the brush cage, at a first end portion of the brush cage adjacent the contact end of the brush. The coil portions respectively engage the hooks. The hooks extend at different angles to a corresponding outer surface of the brush cage.
