<P>PROBLEM TO BE SOLVED: To provide a structure for fixing a handle system of a bicycle, the structure being able to reliably fix a handle system to a fork stem of a bicycle. <P>SOLUTION: A tapered part 15 that gets more tapered in a lower inner diameter in the fork stem 4 is formed. The handle system 20 is inserted from above in the fork stem 4. A fixation member 21 is provided in a lower end part of the handle stem 20, the fixation member 21 radially moving the lower end part of the handle stem 20 to press it on an inner circumference of the fork stem 4 by being pulled up. A pull-up structure 14 for pulling up the fixation member 21 is provided in the handle stem 20. An insertion amount regulating structure 25 for regulating an insertion amount of the handle stem 20 is provided in the handle stem 20 so that the fixation member 21 is retained to be upper than the tapered part 15 when the handle stem 20 is inserted into the fork stem 4 from above along with the fixation member 21. <P>COPYRIGHT: (C)2012,JPO&INPIT |
