Turning device for a self-inking stamp includes a housing and an actuating bracket. The housing has, on each of two opposite side walls, one control cam curved at least in sections for a turning shaft. The bracket is connected and displaceable relative to the housing. On each of two limbs arranged parallel to the housing side walls, the bracket has one turning shaft guide arranged transversely to a displacement direction of the bracket relative to the housing. The guide and the control cam overlap partially at least on a first side and in at least one position of the bracket relative to the housing and configure an opening which is continuous from an outer side, so that a turning shaft is introduceable in the longitudinal direction from the outside into the turning device. The guides have in each case one displaceably mounted sliding bush with a turning shaft bearing.
