Abstract
A shaving apparatus having an external cutting member and an internal cutting member, which is rotationally drivable with respect to said external cutting member, which internal cutting member is supported on the external cutting member both by an axial and a radial bearing means, the internal cutting member being in axially interlocking engagement with the external cutting member, the internal cutting member and the external cutting member, the shaving apparatus further having a drive member for driving the internal cutting member. In operation, in order to minimize the frictional losses between the internal and the external cutting member, the drive member exerts on the internal cutting member exclusively a force for rotationally driving the internal cutting member, while the drive member does not exert any axial force on the internal cutting member.
