Become.

In addition, it may be difficult to set the initial connection state between the handle stem and the fork stem. Therefore, when fixing the positioning member to the handle stem, it is preferable to interpose a position adjusting member. That is, if the position of the positioning member fixed to the handle stem can be adjusted by the position adjusting member, the handle can be accurately positioned with respect to the wheel regardless of the direction in which the receiving member is fixed. The positioning member can be fixed to the handle stem. Therefore, the manufacturing cost and the assembly cost of the receiving member can be reduced, and it is possible to simply and reliably return to the initial position without any positional adjustment from the second and subsequent connection of the handle stem.

In order to separate the handle stem and the fork stem, it is sufficient to simply remove the connecting member and pull it out. To restore the handle stem, the connecting member is fitted after the positioning member and the receiving member are fitted. Just attach it. In addition, if a steadying member for fixing the handle stem to the frame is provided, the folded handle stem does not move, and can be fixed at a desired position, which is convenient.
