Shock absorber

A shock absorber comprising:

• a shock absorber main body including an outer tube and a rod inserted into the outer tube so as to be movable in an axial direction to generate a damping force during extension or contraction;
• an outer tube-side spring seat attached to an outer periphery of the outer tube;
• a rod-side spring seat attached to the rod;
• a coil spring interposed between the outer tube-side spring seat and the rod-side spring seat with the outer tube and the rod inserted inside an inner periphery thereof;
• a stopper provided on the outer tube so as not to be movable in the axial direction;
• a cap body having an annular shape, allowing insertion of the rod, including a flange on an outer periphery thereof, and fixed to a rod-side end of the outer tube;
• and
• a tubular protector sandwiched between the stopper and the flange and fixed to the outer periphery of the outer tube while covering a part of the outer tube to prevent interference between the coil spring and the outer tube.
