ck absorber capable of improving the operability of a piston rod, giving an initial set load to shock-absorbing rubber of a vehicle, and improving the ride quality of the vehicle can be provided. This hydraulic shock absorber includes a cylinder (2), a first support member (11), a cover member (12), a main piston rod (21) extending through the first support member (11), a sub piston rod (22), and a piston (13) between the two piston rods. The hydraulic shock absorber further includes a free piston (15) slidably fitted in the cylinder (2) so that a pipe (90) extends through the free piston (15). A first oil chamber (16) and second oil chamber (17) on the two sides of the piston (13) communicate with each other via a valve. A second support member (14) partitions a second oil chamber (17) and third oil chamber (18), and the free piston (15) partitions the third oil chamber (18) and a gas chamber (19). |
