PROBLEM TO BE SOLVED: To enable transmission of a steering force from an assist steering system to a steering shaft even when a part of a steering force transmission system becomes inoperable in a steering gear of a saddle-riding type vehicle, comprising: a front fork having the steering shaft at the upper end and supporting a front wheel at the lower end; a steering arm attached to the steering shaft; a steering force transmission member rotatably supported by the steering shaft disposed on a vehicle frame; and a steering system link connecting the steering arm and the steering force transmission member.SOLUTION: A steering gear of a saddle-riding type vehicle comprises engagement parts 38d, 72d allowing a steering force transmission member 38 and a steering assistance force transmission member 72 to be engaged so that the steering assistance force transmission member 72 can be rotated around a steering shaft 39 in conjunction with rotation of the steering force transmission member 38, disposed between the steering force transmission member 38 and the steering assistance force transmission member 72.SELECTED DRAWING: Figure 6
【課題】上端部に操向軸を有すると共に下端部で前輪を支持するフロントフォークと、操向軸に取り付けられる操舵アームと、車体フレームに設けられる操舵軸に回動可能に支持される操舵力伝達部材と、操舵アームと操舵力伝達部材とを連結する操舵系リンクとを備える鞍乗型車両の操舵装置において、操舵力伝達系の一部が不作動になった場合でも、アシスト操舵系から操向軸に操舵力を伝達可能とする。【解決手段】操舵力伝達部材38と操舵補助力伝達部材72との間には、操舵力伝達部材38の回動に伴って操舵補助力伝達部材72が操舵軸39の回りに回動されるように操舵力伝達部材38と操舵補助力伝達部材72とを係合可能とする係合部38d,72dが設けられる。【選択図】図6
