The invention relates to a shaving apparatus comprising a first blade ( ) and a second blade ( ) having parallel cutting edges ( ) extending perpendicularly to a cutting direction X of the blades. The second blade follows the first blade, viewed in the cutting direction. According to the invention, the first blade comprises a blocking element ( ) which is provided on a side surface ( ) of the first blade at a distance (d) from the cutting edge ( ) of the first blade, which distance (d) is much smaller than an average diameter of a hair ( ) to be shaved by the apparatus, the first blade being periodically displaceable in the cutting direction by a displacing unit ( ) of the apparatus from a first position, in which the cutting edge of the first blade is close to the cutting edge of the second blade, to a second position. In a prefered embodiment, said distance (d) ranges between 10 &mgr;m and 50 &mgr;m, and is in particular 30 &mgr;m. In a preferred embodiment, the blocking element ( ) is a front surface ( ) of a carrier ( ) of the first blade, a blade part ( ) comprising the cutting edge of the frist blade being mounted on said carrier. The shaving apparatus performs a retractile action, so that a shaving result achieved by the apparatus is maintained for a long period of time.

A micromotor includes a magnetic rotor fixed on a shaft. A stator has at least one winding. Bearings are provided to rotatably support the shaft relative to the stator. The bearings include a first silicon substrate having a V-groove, with a pair of bounding walls. Both bounding walls extend parallel to the shaft. The bearings also include a second silicon substrate having a third bounding wall which also extends parallel to the shaft. The shaft is positioned relative to the stator by the three bounding walls.
