Abstract
An actuator comprising a housing defining an interior cavity for a motor, gear assemblies, and a printed circuit overlying the motor and the gear assemblies. An elastomeric seal band is located between the housing and the cover for sealing the interior cavity of the housing. The seal band includes a plurality of compressible elastomeric beads that abut against the cover and exert a force against the printed circuit board respectively for preventing the vibration of the printed circuit board in the housing. A plurality of curved clips are received in respective clip brackets formed on the housing and the cover respectively for clamping a cover to the housing.
