The invention relates to a hand prosthesiscomprising a chassis to which a plurality of fingerprostheses are articulated, said finger prostheses beingmovable about at least one swiveling axis relative to thechassis and towards each other by means of a drive. Theaim of the invention is to provide a hand prosthesiswhich has a simple control mechanism, works reliably andcan be produced at low cost. For this purpose, the forcetransmission devices on a common drive are coupled to thefinger prostheses in such a manner that starting from arest position and depending on the direction of rotationof the drive at least two finger prostheses go throughdifferent angles of adjustment relative to the chassis.
