Abstract
A power seat slide device for a motor vehicle comprises a rail unit including a stationary rail mounted to a vehicle floor and a movable rail slidably engaged with the stationary rail. The movable rail carries thereon a seat. A twin gear member is rotatably held by the movable rail. The twin gear member includes a worm gear and a first crossed helical gear. An elongate counterpart structure for the worm gear is possessed by the stationary rail. The counterpart structure extends along the stationary rail and is meshedly engaged with the worm gear, so that rotation of the twin gear member about its axis induces a straight-line movement of the movable rail relative to the stationary rail. An electric motor is held by the movable rail. A speed reduction gear unit is held by the movable rail. The speed reduction gear unit is arranged between the electric motor and the first crossed helical member in such a manner that the twin gear member is rotated by the electric motor through the speed reduction gear unit.
