Title: FRONT FORK
Abstract:
The present invention is equipped with: a damper (D), which has a cylinder (5) and a piston rod (6) inserted into the cylinder (5) so as to be movable in the axial direction, and which is interposed between an outer tube (1) and an inner tube (2); a suspension spring (S), which is a coil spring formed by winding a wire, and which forms a tubular partition wall (7) as a result of one axial end of the wire coming into tight contact before the stroke toward the compression side reaches the maximum value; and cushion rubber (8), which can be inserted inside a partition wall (7). When the cushion rubber (8) is inserted inside the partition wall (7), a restriction passage (70), which imparts resistance to the flow of a fluid moving from the inside to the outside of the partition wall (7), is formed between the partition wall (7) and the cushion rubber (8), and when the cushion rubber (8) is inserted further inside the partition wall (7), the cushion rubber (8) is compressed.
