In a dust cover structure of a hydraulic shock absorber 10 covering a piston rod 12 of the hydraulic shock absorber 10 with a bellows-like dust cover 30, the dust cover 30 is divided into upper, intermediate and lower regions A, B, and C extending in a longitudinal direction. Thicknesses Ta and Tc of bellows portions 33A and 33C in the upper region A and the lower region C are made thin, and a thickness Tb of a bellows portion 33B in the intermediate region B is made thick.
