<p>In the present invention, disclosed is an actuator for opening and closing a fuel filler door which minimizes generated noise by buffering and distributing impact, generated when the filler door is opened and closed, by applying a damper made of a impact absorption material on an assembly portion between a sector gear, which is linked with a worm gear rotated by a driving motor and pivots, and an operation rod, which is linked with the sector gear and linearly moves. The actuator includes: the worm gear (22) installed on the driving motor (20); the sector gear (30) having a link arm (32) which is engaged with the worm gear (22) to be installed to be able to pivot and protrudes from one side to an outer side in a radial direction; the operation rod (40) which includes an assembly slot formation unit (42) to be joined with the link arm (32), is linked with the sector gear (30), and can move in a linear direction; and the damper (50) which is installed in the assembly slot formation unit (42) of the link arm (32) and accommodates a joining protrusion (36) of the link arm (32) in a slot space therein.</p> |
