ABSTRACT:
A structure of a motor driven driving mechanism of a sewing machine comprises a motor mounted on one side of the sewing machine and a driving mechanism disposed inside the frame of the sewing machine driven by the motor. A rotor shaft extends out of the cover, the rotor shaft comprises a connecting portion for connecting with the driving mechanism, and at least one resilient element is disposed on two sides of the connecting portion for connecting the connecting portion with the driving mechanism. Since the rotor shaft rotatably drives the driving mechanism, therefore frictional or ramming effects among the assembly parts can be eliminated or at least substantially reduced. Thus noise during operation and the damage to the mechanical parts can be effectively reduced.
