Abstract
A conveyance seat includes: a pair of lower rails; a pair of upper rails, each of which is slidably assembled to the corresponding lower rail; an electric drive mechanism; a pair of brackets, each of which is assembled to an upper surface of the corresponding upper rail; and a pair of buffer members, each of which is arranged between the upper surface of the upper rail and the bracket. The electric drive mechanism includes a drive source fastened to one of the brackets; a shaft; a pair of screws assembled one to each rail of the lower rails or the upper rails; a pair of nuts; and a pair of gear subassemblies. The electric drive mechanism electrically slides each upper rail with respect the corresponding lower rail by the screw moving relative to the nut or by the nut moving relative to the screw, by rotation of the shaft when the drive source is driven.
