Disclosed is a differential side oil seal preventing lubricating oil from being leaked from the interior of a differential gear housing to the outside. The differential side oil seal comprises a support frame, a sealing member and an assembling member. The support frame is a member made of a rigid material in a ring-shape and is inserted into the interior surface of the differential gear housing. The sealing member is a ring-shaped member made of an elastic material to be coupled to a support frame, and seals the rotary shaft by covering the outer circumferential surface of the rotary shaft arranged on the interior of the differential gear housing. The assembling member is a member made of a rigid material and having a ring-shape and has the front end fixedly coupled to the support frame and the rear end spaced from the sealing member to be arranged on the rear side and protecting the sealing member by covering the sealing member. The tip of the rear end of the assembling member is bent backward at a point of the rear end of the assembling member, which has a minimum diameter, to have a U-shaped section or is bent backward at the point of the minimum diameter to be rolled into a circular shape. |
