An adjusting device for positioning a load comprises a spindle-type lifting gear, first and second bearing brackets with bearing pins that engage in a respective bearing bush of the gear unit housing for the swivelable bearing support of the gear unit housing of the spindle-type lifting gear, a driving motor with a motor shaft, and a motor flange unit with a flange housing that is rigidly connected to the driving motor on one side and to the gear unit housing on the other side. The flange housing is secured to one of the side surfaces of the gear unit housing at which the bearing bushes of the gear unit housing are arranged. The driveshaft of the spindle-type lifting gear extends parallel to the swiveling axis around which the spindle-type lifting gear is swivelable. The flange housing has, on the side facing the swiveling axis, a recess into which part of the end portion of the arm of the bearing bracket adjacent to the flange housing projects.
