In a dust cover made of an elastic material such as rubber, which seals airtightly to prevent dust from entering the part, an outwardly protruding flange part is integrally formed with the large-diameter fitting part, and the flange part is reinforced with steel material or the like. What is claimed is: 1. A dust cover, characterized in that a dust cover is embedded therein, and a protrusion that protrudes upward is integrally formed on the upper surface of the tip of the flange portion, either continuously or discontinuously over the entire circumference. (2) The dust cover according to claim 1, wherein the protrusion is a lip-shaped protrusion. (3) The dust cover according to claim 1, wherein the protrusion is a protrusion with a substantially semicircular cross section.
