Elastic bush and motor using same

An electric motor using an elastic bush, the electric motor comprising:

• a yoke assembly generating a magnetic field;
• an armature assembly configured such that a coil is wound on a core slot formed in a core, and disposed in the yoke assembly to rotate about a rotating shaft;
• a front bush coupled to a side of the rotating shaft to reduce a gap with a peripheral component;
• and
• the elastic bush fitted over the rotating shaft, located between the armature assembly and the front bush to prevent a gap between the front bush and the armature assembly,
• wherein the elastic bush comprises a bush body and a circular separation plate spaced apart from each other and connected to each other via a connecting leg, a relative distance between the bush body and the circular separation plate varying as the connecting leg is elastically deformed,
• wherein each connecting leg comprises:
• a body connecting portion extending away from a radial side of the bush body and extending parallel to the circular separation plate;
• and
• an extending portion connected at a first end thereof to the body connecting portion in a direction perpendicular to the body connecting portion, and connected at a second end thereof to a bottom of the circular separation plate, and
• wherein the height of the bush body in an extending direction of the rotating shaft is greater than the distance between the bush body and the circulation separation plate.
