A hydromount (2) includes: a housing (4) and a compensating diaphragm (6), which enclose a hydraulic volume (8), a partition wall (12), which partitions the hydraulic volume (8) into a working chamber (14) and into a compensating chamber (16). The partition wall (12) contains a transfer channel (18), via which the two chambers (14, 16) are connected to one another, and wherein the partition wall (12) has an opening, in which there is a diaphragm or membrane (20) of flexible, elastomeric material clamped between two components (22, 24), wherein the diaphragm (20) is clamped between the two components (22, 24) in such a way that, as a result of the clamping, a radial pretension is produced in the diaphragm (20).
