Zusammenfassung:	An oil seal apparatus and a blower including the same are disclosed. The oil seal apparatus and the blower can assemble a body pipe quickly regardless of assembling direction of the body pipe when assembling the body pipe by forming a plurality of oil return holes, i.e., forming more than four or five oil return holes at upper portion, lower portion, left portion, and right portion of an outboard surface of the body pipe. The oil seal apparatus may be mounted in a shaft through-hole formed at an oil box of a blower. The oil seal apparatus may include: a body pipe mounted on a rotation shaft penetrating through the shaft through-hole and provided with a step portion formed at an exterior circumference of the body pipe; at least one collecting groove for collecting oil which is formed at an interior circumference of the body pipe; and more than four oil return holes evenly spaced from each other, formed at the body pipe slantedly from an inboard side to an outboard side, and communicating with the collecting groove.
