PROBLEM TO BE SOLVED: To accurately and surely execute interlocking operation between tilting of a vehicle body 44 and rotation of a steering shaft 53 for a long period of time.SOLUTION: A first bevel gear 56 is fixed to a lower end part of a steering shaft 53, and a second bevel gear 57 is supported by a front frame 31, and when tilting of a vehicle body 44 is interlocked with rotation of the steering shaft 53 by meshing these first bevel gear 56 and second bevel gear 57, even when slight dust intrudes between the first and second bevel gears 56 and 57 during traveling of a tricycle, an influence is hardly received from the dust since both the bevel gears only partly mesh, and the bevel gears are durable for a long-term use since strength is greatly high as compared with a wire, and interlocking operation can be accurately and surely executed for a long period of time.SELECTED DRAWING: Figure 4

    【課題】車体44の傾動とステアリング軸53の回転との連動動作を長期間正確かつ確実に行う。【解決手段】ステアリング軸53の下端部に第1傘歯車56を固定するとともに、前フレーム31に第2傘歯車57を支持させ、これら第1傘歯車56と第2傘歯車57とを噛み合わせることで車体44の傾動とステアリング軸53の回転とを連動させるようにすれば、三輪車両の走行中に多少の塵埃が第1、第2傘歯車56、57間に侵入しても、両傘歯車はその一部でしか噛み合っていないので、該塵埃から殆ど影響を受けることはなく、しかも、傘歯車はワイヤに比較して強度が大幅に高いため、長期間の使用にも耐えることができ、前記連動動作を、長期間正確かつ確実に行うことができる。【選択図】図4
