A hydraulic damper includes: a cylinder having a cylinder tube; a piston slidingly movable within the cylinder tube; a piston rod integrally movable with the piston; a first chamber and a second chamber into or from which fluid flows by sliding movement of the piston relative to the cylinder tube; a piston port portion connecting the first chamber and the second chamber; a damping force generating device disposed downstream of the piston port portion through which the fluid flows; and a sub-valve disposed upstream and/or downstream of the damping force generating device. The sub-valve is provided with a sub-valve port portion that is connected to a flow path of the piston port portion. A total cross-sectional area of a flow path of the sub-valve port portion is smaller than a total cross-sectional area of the flow path of the piston port portion.

A hydraulic shock absorber includes an enclosure member. The enclosure member has an inflow path which guides oil from the outside to the inside. The inflow path is arranged so that an axis of the inflow path deviates from a central axis of a rod.
