- Figure 7 is a plan view showing the serial production method the renewal according to the insert can be recognized.

FIG. 8 is a view similar to FIG. 7.

According to a first embodiment and as can be seen in FIGS. 1 to 3, one half of the housing of a shaving device is shown in FIG shown, this housing half comprising an outer 2 and an inner side 3 (Figure 3), in which one as a damping cushion Acting insert 4 inserted on the outer side 2 of the housing half is ο

In the present case, the cushion 4 is essentially trapezoidal formed (Figure 2) and has on its inner surface a plurality of thorns 5 and flexible ribs 6, these thorns and ribs are molded in one piece with the pillow. The ribs 6 are preferably mutually perpendicular and form partitions, between which cavities 9 arise. FIG. 1 also shows that the outer side of the cushion 4 is somewhat roughened, so that the device is more easily grasped · The outer side of the cushion 4 can also be patterned as desired «
