A dryshaving apparatus in which a shaving head and an oscillating-armature motor constitute an assembly. This assembly is mounted in the housing of the dryshaving apparatus by elastic elements only, at least one elastic element being a strip-shaped integral hinge extending transversely to the oscillating movement and connected at one end to the assembly and at its other end to the housing. The assembly together with the elastic elements has a mechanical resonant frequency less than the oscillation frequency, divided by 2ROOT 2, of the parts of the assembly performing the oscillating movement.
