    • Shaving apparatus with at least one cutting unit (3) having an outer cutter (4) and an inner cutter (6) which is rotationally drivable with respect to the outer cutter by means of an driving shaft (18) of a driving device, which driving shaft exerts a prestress force (FY) on the inner cutter in the direction of the outer cutter. During cutting of a hair, the hair exerts a cutting force (FR) on the inner cutter (6), which force has a direction that is opposite to the driving force (FD) for driving the inner cutter. Claimed is that the driving device comprises only one rotationally drivable coupling element (11) having at least one driving surface (12), that the driving shaft (18) bears axially (32,33) on the outer cutter (4) via said coupling element (11), and that the inner cutter (6) comprises at least one driven surface (13) cooperating with said driving surface (12) for exerting the driving force (FD), the direction of the driving force (FD) being substantially perpendicular to the driving surface (12) and the driven surface (13) .
    • 具有至少一个具有外部刀具(4)和内部刀具(6)的切割单元(3)的剃须装置,所述内部刀具通过驱动装置的驱动轴(18)相对于外部刀具可旋转地驱动,所述驱动装置 驱动轴在内切割器上向外切割器的方向施加预应力(FY)。 在切割头发期间,头发在内切割器(6)上施加切割力(FR),该切割力具有与用于驱动内切割器的驱动力(FD)相反的方向。 要求保护的是,驱动装置仅包括一个具有至少一个驱动表面(12)的可旋转驱动的联接元件(11),驱动轴(18)经由所述联接器轴向地(32,33)支承在外部刀具 并且内切割器(6)包括与所述驱动表面(12)配合以施加驱动力(FD)的至少一个从动表面(13),驱动力(FD)的方向基本上 垂直于所述驱动表面(12)和所述从动表面(13)。
