A seat slide device including two slide assemblies each having an upper slide element which is slid by a drive unit along a lower track element via a flexible drive transmission element. The drive unit is provided in the seat and the flexible drive transmission element is arranged between the drive unit and two slide assemblies, such that a part of the flexible drive transmission element extends along a direction in which the two slide assemblies extend. An auxiliary flexible drive transmission element may be added to insure imparting a drive force to the upper slide element. A lock operation/control system is provided to insure precise locking and unlocking of the upper slide element with respect to the lower track element, while simultaneously effecting selective switch-over operation of the drive unit to cause forward and backward movement of the upper slide element along the lower track element.
