Electric geared motor unit comprises two bearings (20, 21). Bearings have male and female positioning attachments (29), such as tenons (41, 42) and mortises (39), able to work with each other so as to fix /stop bearings in specific position. One bearing (21) has catch (30) that is pressed against periphery of one toothed wheel (18) of electric unit. Catch works together with teeth of toothed wheel to allow its rotation corresponding to pre-stress of spring (not shown). An Independent claim is also included for the electric lock.
