A front fork is provided with a plurality of adjusters, while including a spring adjuster. In a front fork according to the means for solving the problem of the present invention, a spring adjuster is rotatably mounted on a position eccentric to a center of a cap as viewed in an axial direction and includes a screw portion disposed in an outer periphery protruded into a fork main body, and a plate in which the screw portion of the spring adjuster is screwed to change support positions of a suspension spring is brought into contact with a case (tubular member) at two points on both sides in a circumferential direction of the normal of the case that passes a mounting center of the spring adjuster. Accordingly, while being prevented from rotating, the plate can be downsized and can be disposed so as not to interfere with first and second adjusters.
