DUST COVER

Japanese Patent JP2017082889

A

PROBLEM TO BE SOLVED: To provide a technology which secures the rigidity of a dust cover, and reduces the resistance of an airflow of a disc rotor in a peripheral direction.SOLUTION: In a dust cover 10, a plurality of beads are arranged at an opposing part 12 opposing a disc rotor 90. The plurality of the beads include an arc-shaped first bead 22 arranged in a region including a gravity center of the opposing part 12, and a second bead 24 and a third bead 26 which are arranged in arc shapes at the outside of the first bead 22 in a radial direction. The second bead 24 and the third bead 26 are overlapped on each other within a range larger than 10° with respect to the first bead 22 at an angle with an axle center as an apex angle. The second bead 24 extends from the axle center from an end of the third bead 26 side, straddles a semi-linear line passing through a first fastening part 14 of the opposing part 12, and extends at angles of 20° or larger. The third bead 26 extends from the axle center from an end of the second bead 24 side, straddles a semi-linear line passing through a second fastening part 16 of the opposing part 12, and extends at angles of 20° or larger.SELECTED DRAWING: Figure 1
