Rotary shaver with improved support structure for shaving heads

A shaving device comprising a base structure and a head structure, wherein the head structure comprises:

• a head support structure configured to hold at least one shaving head;
• a coupling element arranged in a central area of the head structure;
• and
• wherein the base structure comprises:
• a retaining structure configured for releasably retaining the coupling element for coupling the head structure to the base structure;
• and
• the base structure being free of support elements in an area of an outer circumference of the head structure such that the head structure, when coupled to the base structure, is not supported in the area of its outer circumference, and the head structure, when coupled to the base structure, being substantially only retained on the base structure by a retaining force exerted by the retaining structure on the coupling element,
• wherein the coupling element is a shaft-like element protruding from the central area of the head structure and comprising, at a distal end thereof, a sloped surface facing the head support structure,
• wherein the retaining structure comprises
• a retaining recess for receiving the coupling element;
• and
• a spring element at least partly provided in the retaining recess, the spring element being arranged for engaging the sloped surface of the coupling element such that the coupling element is retainable in the retaining recess,
• and wherein a collar is provided around the coupling element for abutting on an edge around the circumference of the retaining recess.
