There is described a movement actuator (10) comprising: a first actuator part (11; 41) and a second actuator part (12; 20) that are rotatably mounted relative to one another; and an electromotor (73) and a transmission system (60) coupled between the electromotor (73) and the two actuator parts (11, 12; 41, 20) for rotating these actuator parts (11, 12; 41, 20) relative to one another. The transmission system (60) comprises a worm wheel (61) and two worms (63, 64) concentrically attached thereto on two sides, preferably manufactured in one piece, the diameter of the worm wheel (61) being greater than the diameters of the worms (63, 64), which worms drive a gear wheel (40) with the interposition of respective intermediate gear wheels (65, 66), so that the movement actuator can be of a particularly compact and even modular design while maintaining its strength. |
