摘要： Shaving apparatus having at least one pivotable cutting unit (3) comprising an external cutting member (4) and an internal cutting member (6) which is drivable relative to said external cutting member, a drive mechanism (8) for driving said internal cutting member (6) into rotation, and a coupling member (18) having a coupling head (19) and a coupling body (20), which coupling head can be coupled to a coupling element (16) of the internal cutting member (6) in a detachable manner, said coupling body (20) being coupled to said driving mechanism (8). The coupling head (19) can be inserted into a cavity (21) of the coupling head (19). For driving said internal cutting member into rotation, the coupling head (19) comprises curved surfaces (25) for cooperation with surfaces (28) of said cavity (21). To improve the drive system, the coupling head (19) and the cavity (21) of the coupling element (16) have an approximately triangular shape which is rotationally symmetrical through 120?? as seen in the direction of the axis of rotation (24) of the coupling head (19).
