PROBLEM TO BE SOLVED: To provide a motor cycle which facilitates reaction force adjustment of a buffer between when one passenger rides on a motor cycle and when two passengers ride on the motor cycle or a heavy luggage is mounted on the motor cycle, especially, facilitates a work for returning reaction force to that when one passenger rides on the motor cycle from reaction force adjustment when two passengers ride on the motor cycle or a heavy luggage is mounted on the motor cycle.SOLUTION: A motor cycle comprises: a swing arm 20 which is supported to a vehicle body 10 so as to oscillate freely, and which rotatably supports a rear wheel WR; a buffer 30 which connects the swing arm 20 and the vehicle body 10 and which absorbs impact from a road face; and a torsion bar mechanism 40 which has a torsion bar 41 which can generate reaction force R to the oscillation when the swing arm 20 oscillates and which is different from the buffer 30. The torsion bar mechanism 40 includes a reaction force adjustment mechanism 50 which can change a magnitude of the reaction force R, and the reaction force adjustment mechanism 50 has a reaction force zero adjustment part 500 which generates no reaction force R.SELECTED DRAWING: Figure 2

    【課題】1人乗りの時と、2人乗りの時や重い荷物を積んだ時とでの、緩衝器の反力調整が容易で、特に、2人乗りの時や重い荷物を積んだ時のための反力調整から、1人乗り時の反力に戻す作業が簡単な自動二輪車を提供する。【解決手段】。車体10に揺動可能に支持され、後輪WRを回転可能に支持するスイングアーム20と、スイングアーム20と車体10とを連結し、路面からの衝撃を吸収する緩衝器30と、緩衝器30とは別の、スイングアーム20の揺動時に揺動に対する反力Rを発生させることが可能なトーションバー41を有するトーションバー機構40を備え、トーションバー機構40は、反力Rの大きさを変更することができる反力調整機構50を含み、反力調整機構50は、反力Rを発生させない反力ゼロ調整部500を有している。【選択図】図2
