Composite oil seal having electric corrosion prevention function

A composite oil seal having an electric corrosion prevention function, the composite oil seal being mounted on a shaft in a motor housing to prevent leakage of oil in the motor housing, the composite oil seal comprising:

• a seal main body formed of an elastic material, the seal main body having an outer circumferential surface formed to be in tight contact with an inner circumferential surface of the motor housing and at least one lip protruding inwards so as to be in contact with an outer circumferential surface of the shaft;
• and
• an electrical path fabric formed of woven metallic yarns, the electrical path fabric being mounted to the seal main body to electrically connect the shaft to the motor housing so that current induced in the shaft flows to the motor housing,
• wherein the electrical path fabric is formed in a circular disc-shape having a central hole through which the shaft passes, an inner rim, an outer rim, a first flat side attached to the seal main body, and a second flat side opposite to the first flat side, and
• wherein a diameter of the central hole is smaller than a diameter of the shaft and a diameter of the electrical path fabric is greater than a diameter of the inner circumferential surface of the motor housing such that the inner rim and the outer rim are bent in a direction that the second flat side faces, with the first flat side in direct contact with both the outer circumferential surface of the shaft and the inner circumferential surface of the motor housing.
