Method of manufacturing shock absorber

A method of manufacturing a shock absorber, the shock absorber comprising:

• an inner cylinder;
• an outer cylinder having a bottomed tubular shape, which defines, in combination with the inner cylinder, a reservoir;
• a piston inserted into the inner cylinder;
• a piston rod having one end coupled to the piston and another end extending to an outside through an opening of the outer cylinder;
• a damping force adjustment mechanism provided to a side portion of the outer cylinder, the damping force adjustment mechanism including a damping unit capable of adjusting a damping force and an actuating unit capable of actuating the damping unit;
• and
• a spring seat, which is fixed to the outer cylinder and is configured to receive a suspension spring,
• the method comprising:
• a fastening step of fastening the damping unit and the actuating unit together, which are provided to the side portion of the outer cylinder;
• and
• a spring-seat fixing step of fixing the spring seat to the outer cylinder after the fastening step, wherein the spring-seat fixing step comprises a pushing step of pushing a bottom portion of a shock absorber main body under a state in which the another end of the piston rod is facing down.
