Shaving apparatus having at least one cutting unit with an external cutting member and a rotatable internal cutting member each the external and internal cutting members having cooperating cutting edges forming bearing surfaces of a first bearing, and a second bearing with bearing surfaces. To minimize the friction between the cutting edges, a support device having visco-elastic properties is provided between the two bearings. During operation, the distance between the bearing surfaces of the first bearing adjusts to the distance between the bearing surfaces of the second bearing. During cutting of hairs, the support device behaves as a stiff element whereas during periods in which no hairs are cut, the support device behaves relatively soft so that the cutting gaps between the cutting edges are closed. |
