PROBLEM TO BE SOLVED: To improve the radial rigidity of an accordion-like part in a dust cover.SOLUTION: There is provided a dust cover 70 cylindrically formed by an elastic body to cover the periphery of a joint for connecting a rack shaft to a tie rod. The dust cover 70 has an accordion-like part 81 formed in an accordion-like state, and in the accordion-like part, a honeycomb pattern 84 is formed on either one or both of the outer and inner peripheral faces of the accordion-like part. The honeycomb pattern is formed by partially providing a thick wall part 83 thicker than the periphery so as to protrude from the peripheral face of the accordion-like part, and the thick wall parts positioning at two sides among six sides of each hexagon composing the honeycomb pattern are disposed along the peripheral direction of the accordion-like part. |
