A lifter for an automotive seat, comprising a drive assembly including a long forward link member and a short rearward link member, and an operation mechanism including a drive shaft, a housing rotatably provided on the drive shaft, a gear provided in the housing, the gear being connected to the drive shaft, and a pair of first and second pawl members rotatably pivoted in the housing, with such arrangement that either of those pawl members is selectively brought to engagement with the gear by means of a switch-over cam. An operation lever is equipped with the housing, and both drive assembly and operation mechanism are operatively connected together. Thus, repeated reciprocal rotation of the operation lever attains an easy adjustment of the seat at a desired higher or lower level in a swinging manner, which permits a small rotation range of the operation lever.
