Abstract
A suspension fork 10 for a bicycle is provided with a fork portion 40 for supporting a front wheel 12, a sleeve-like first fork stem 41, a sleeve-like second fork stem 42, a coil spring 43, an adjustment bolt 44, and a coupling portion 45. The first fork stem 41 is rotatably supported by a head portion 21, and the second fork stem 42 extends from the fork portion into an interior of the first fork stem 41. The coil spring 43 biases the first fork stem 41 and the second fork stem 42 away from each other. The coupling portion 45 includes a rotation preventing key 51 and an oblong slit 52 for coupling the first fork stem 41 and the second fork stem 42, and allows the first and second fork stems to be movable in an axial direction relative to each other but unrotatable relative to each other.
