ABSTRACT:
The invention concerns a clockwork motor, particularly but not exclusively, for toys, wherein an escapement consisting of a friction memeber that is pressed resiliently against a sliding surface moving with a part of the clockwork motor running down under the action of a mainspring, and wherein the pressure force for the friction member is arranged to be approximately proportional at any given moment to the driving force of the mainspring at the moment. The friction member is mounted on a carrier spaced from and movable relative to the sliding surface, and a stationary end of the mainspring engages with the carrier.
