The hair-cutting unit (4) further comprises a holding member (7) which is pivotable relative to the supporting member (6) between a holding position of holding the cutting members (41, 42) in an operational position in the supporting member (6), and a releasing position of releasing the cutting members (41, 42) for removal from the supporting member (6), and a biasing mechanism (8) which is configured to bias the holding member (7) towards the holding position. At least in an opened position of the supporting member (6), pivoting of the holding member (7) out of the holding position is prevented solely by the biasing force of the biasing mechanism (8).

A shaving unit (12) has an assembly of at least two rotary hair-cutting units (13) and a supporting member (26) to which the hair-cutting units are connected. The assembly of the hair-cutting units and the supporting member can move linearly relative to a base portion (20) between a first, retracted, position and a second, extended, position. The supporting member is biased by a spring member (30) away from the base portion. The hair-cutting units each have an individual hair-collecting chamber and they are individually pivotable relative to the supporting member. The base portion comprises a coupling structure (44) by means of which the shaving unit can be releasably coupled to the main housing (15) of a shaving device.

A shaving apparatus (1) having a first shaving unit portion (7) connected to a main housing (2) and accommodating a single driven input member (9) rotatable about an axis of rotation. A second shaving unit portion (8) of the shaving apparatus has a hair-cutting unit (12) and a drive unit (13) which transmits a driving force from the single driven input member to an internal cutting member (19) of the hair-cutting unit. The second shaving unit portion is manually rotatable relative to the first shaving unit portion about the axis of rotation of the single driven input member. An adjustment system (24) has a sensing unit (28, 29) configured to have an output property which varies with the angular position of the second shaving unit portion relative to the first shaving unit portion about the rotational axis. The adjustment system adjusts an operational parameter of the shaving apparatus in dependence on the output property of the sensing unit.
