To allow easy adjustment of the hardness of a suspension by a rider on a bicycle.

A suspension fork 10 for a bicycle is equipped with a fork portion 40 supporting a front wheel 12, the first fork stem 41, the second fork stem 42, a coil spring 43, a load adjustment part 44 and a connector 45. The first fork stem 41 is rotatably supported on a head 21. The second fork stem 42 is disposed axially movably within the first fork stem 41. The coil spring 43 biases the two fork stems 41, 42 in opposite directions. The load adjusting part 44 is equipped with an adjusting screw which is moved axially to change the initial length of a coil spring 43 and a rotating part which is capable of relative axial movement and incapable of relative motion. The connector 45 connects two fork stems 41, 42 allowing relative axial movement while restricting relative rotation therebetween.
