One of a pair of the hydraulic shock absorbers each mounted in the right and left sides of a front wheel for a two-wheel vehicle includes a contraction-side damping valve ( 5 a) disposed in a flow passage ( 11 ) communicating a rod-side oil chamber (R 1 ) with a piston-side oil chamber (R 2 ), the contraction-side damping valve ( 5 a) permitting an operating oil to flow from the piston-side oil chamber (R 2 ) to the rod-side oil chamber (R 1 ) only when a volume in the piston-side oil chamber (R 2 ) is reduced, and a contraction-side check valve ( 6 ) disposed in a flow passage ( 10 ) communicating the piston-side oil chamber (R 2 ) with the reservoir (R), the contraction-side check valve ( 6 ) permitting the operating oil to flow from the reservoir (R) to the piston-side oil chamber (R 2 ) only when a volume in the piston-side oil chamber (R 2 ) is increased.
