Abstract: A shock absorber is provided. The shock absorber of the present invention includes a shock absorber main body, a damping passage, a primary damping force generation component, and a secondary damping force generation component. The shock absorber main body has an outer tube and a rod and is stretchable. The damping passage communicates operating chambers with each other provided in the shock absorber main body. The primary and secondary damping force generation components are provided in series with the damping passage. The secondary damping force generation component includes a secondary valve, an annular facing portion, and a valve stopper. The annular facing portion faces the secondary valve with an annular gap between the annular facing portion and the secondary valve. The valve stopper has elasticity to allow bending, and when the secondary valve bends and comes in contact with the valve stopper, restricts the secondary valve from bending.
