A linear actuator may include a rail including a gear rack extending along a longitudinal direction of the rail and a pinion unit configured to slidably engage the gear rack. The gear rack may include at least one no-teeth section among a row of teeth and the at least one no-teeth section may extend over a length. The pinion unit may include two pinion gears both configured to engage the gear rack, the two pinion gears being spaced apart from each other by a center-to-center distance along the longitudinal direction; and an electric motor configured to drive the two pinion gears. The length may be equal to or longer than two pitches of the teeth of the gear rack and shorter than the center-to-center distance.
