ボトムブリッジと一体形成したことを特徴としている。(Means for Solving the Problems) In order to achieve the above points, the present invention provides a motorcycle, etc., which is supported by welding and joining a pair of left and right front fork pipes made of pipe material with a bottom bridge extending from a plate material. The front 1 fork is characterized in that a reinforcing member for reinforcing the joint between the front j fork pipe and the bottom bridge is integrally formed with the bottom bridge.
以下、本発明を自動二輪中に適用した一実施例についτ
図面に基づいて説明する。Hereinafter, an example in which the present invention is applied to a motorcycle will be described.
The explanation will be based on the drawings.

されている。The bottom bridge 14 is formed of a plate material and is welded to the front fork pipes 5a, 5a, and there are reinforcing gussets 1zla, 1 roughly on the L side and below this joint.
4b are each integrally formed, and these gussets 14a,
14b is also welded to the front fork pipes 5a, 5a.

とができる。[Effects of the Invention] As described above, the present invention provides a front fork of a motorcycle or the like in which a pair of right and left fronts 1 made of a pipe material are welded and supported by a bottom bridge made of a plate material to a fork pipe. Since the reinforcing member that reinforces the joint between the front fork pipe and the bottom bridge is integrally formed with the bottom bridge, there are fewer welding points than before, and the front fork pipe and bottom bridge can be easily matched and welded. It can be done.
