Abstract: A shaving apparatus has at least one cutting unit detachably coupled to a drive mechanism via a coupling having first and second coupling members. The second coupling member has a coupling cavity. A coupling head of the first coupling member is in a form-locking engagement in the coupling cavity to transfer a driving force, and is detachable from the coupling cavity by movement in an axial direction parallel to an axis of rotation of the cutting unit. The second coupling member has a plurality of recesses, each recess extending in a radial direction from the coupling cavity and being delimited by two radially extending side wall sections. Each of the two radially extending side wall sections forms an edge with a bottom surface of the second coupling member, and the edges of each recess converge in a radially outward direction in relation to the axis of rotation.

Abstract: The invention relates to a shaving apparatus with at least one cutting unit (3) detachably coupled to a drive mechanism (8) via a coupling (18, 16), and to such a coupling. Said coupling comprises a second coupling member (16) having a coupling cavity (21). A coupling head (19) of a first coupling member (18) is in a form-locking engagement in said coupling cavity to transfer a driving force, and is detachable from said coupling cavity by movement in an axial direction (24) parallel to an axis of rotation of the cutting unit. Said second coupling member comprises a plurality of recesses (31), each recess extending in a radial direction from said coupling cavity and being delimited by two radially extending side wall sections (31a,31b). Each of said two radially extending side wall sections forms an edge (32a, 32b) with a bottom surface of said second coupling member, and the edges of each recess converge in a radially outward direction in relation to said axis of rotation.
