PROBLEM TO BE SOLVED: To provide a structurally new dust cover that achieves smooth contraction deformation of a bellows cylinder part while making a length during contraction short by reducing the number of main valley parts.SOLUTION: A dust cover 10 includes a bellows cylinder part 12 in which a plurality of main valley parts 14 depressed to an outer peripheral side are continuously provided. The main valley part 14 comprises a set of inclined wall parts 16 and 16 that are inclined to an axial outside toward an outer periphery. An inclination angle (&bgr;) of an outer peripheral part 60 of the inclined wall part 16 is set smaller (α>&bgr;) than an inclination angle (α) of an inner peripheral part 58. |
