In order to achieve the above object, in a front fork F according to the means for solving the problem of the present invention, first and second adjusters 5, 6 are mounted on a cap 4 so as to be axially movable, and a contact portion 52 of the first adjuster 5 in contact with a first adjustment rod 7 and a contact portion 62 of the second adjuster 6 in contact with a second adjustment rod 8 are displaced in an axial direction of a vehicle body tube 2 so as not to interfere with each other. Therefore, even when each of the first and second adjusters 5, 6 moves in the axial direction with respect to the cap 4, the corresponding first and second adjustment rods 7, 8 can be moved independently without being interfered with each other.
