A hydraulic shock absorber includes: a cylinder; a piston rod on which a first piston, a valve, and a second piston are disposed sequentially from one end side; and an oil lock portion that is disposed on the one end side inside the cylinder, and that forms a gap flow path between the oil lock portion and an outer circumferential surface of the first piston. The first piston has a piston internal flow path, and is displaceable in an axial direction of the piston rod. When the piston rod moves toward the one end side, the first piston relatively moves toward the other end side with respect to the piston rod and the other end side of the first piston abuts against the valve, so that due to a flow of working oil passing through the piston internal flow path, the valve bends to generate damping force.
