PROBLEM TO BE SOLVED: To secure a length of a swing arm and improve flexibility of the layout of the swing arm in a front wheel suspension device of a saddle-riding type vehicle in which the handle is connected with a front fork through a link member.SOLUTION: A front wheel suspension device 1 of a saddle-riding type vehicle includes: a front fork 10 supporting a front wheel 9; a steering member 25 which is rotated around a steering axis line C1 in conjunction with the operation of a handle 20; and a link member 30 comprising an upper link 31 swingably connected with the steering member 25 and a lower link 32 swingably connected with the upper link 31 and the front fork 10; a swing arm 40 having upper and lower arms 41, 42; and a support member 15 forming a steering axis line C2 and swingably supporting front end parts of the upper and lower arms 41, 42. The support member 15 has a cylindrical shape and supports the front fork 10 at its radial inner side so that the front fork 10 may rotate around the steering axis line C2.SELECTED DRAWING: Figure 1
【課題】ハンドルとフロントフォークとをリンク部材を介して連結した鞍乗り型車両の前輪懸架装置において、スイングアームのレイアウトの自由度を向上しつつスイングアームの長さを確保する。【解決手段】前輪9を支持するフロントフォーク10と、ハンドル20の操作に伴って操舵軸線C1の回りに回動される操舵部材25と、操舵部材25に揺動可能に接続される上リンク31と、上リンク31及びフロントフォーク10に揺動可能に接続される下リンク32とによって構成されるリンク部材30と、上下アーム41,42を有するスイングアーム40と、ステアリング軸線C2を形成すると共に、上下アーム41,42の前端部を揺動可能に支持する支持部材15と、を備える鞍乗り型車両の前輪懸架装置1において、支持部材15は、筒状をなし、支持部材15の径方向内側でフロントフォーク10をステアリング軸線C2の回りに回動可能に支持する。【選択図】図1
