Abstract
The front fork () includes a fork main body () in which an inner tube () is inserted into an outer tube () to enable free expansion and contraction, a damper () generates a damping force when a rod () moves within a cylinder () as the fork main body () expands and contracts, an air chamber () delimited by a free piston (), which compensates for variation in the internal volume of the cylinder () caused by invasion and retreat of the rod () into and from the cylinder (), a pressurizing spring () housed in the air chamber (), which biases the free piston () in a direction for enlarging the air chamber (), and a sub-spring () which biases the free piston () in a direction for shrinking the air chamber () in opposition to the pressurizing spring ().
