1. A shock absorber comprising:
a cylinder in which a working fluid is sealed;
a piston provided to be slidable in the cylinder and partitioning an inside of the cylinder into two chambers;
a piston rod connected to the piston and extending to an outside of the cylinder;
a passage through which a working fluid flows from the chamber on an upstream side to the chamber on a downstream side in the cylinder due to movement of the piston;
a first damping force generation mechanism provided in the passage formed in the piston to generate a damping force;
a second damping force generation mechanism disposed separately from the first damping force generation mechanism and provided on the piston rod; and
a fluid storage mechanism disposed separately from the second damping force generation mechanism and provided on the piston rod, wherein
the fluid storage mechanism includes:
a flexible disc which deforms before the second damping force generation mechanism opens; and
a plate-shaped biasing member
having a hole portion formed as a flow path of the working fluid between an inner circumferential end portion and an outer circumferential end portion,
being inserted with the piston rod at the inner circumferential end portion, and
being fixed to the piston rod, and wherein
the biasing member is in contact with the flexible disc over an entire circumference, and forms a part of a fluid storage chamber.
