To achieve a change of a tread width of a lean vehicle.SOLUTION: By changing positions of a first side member 11 and a second side member 12 with each other, either one of a first state and a second state, whose tread widths are different from each other is selected, and the following conditions are satisfied: an upper left leaning rotating shaft LUL and a lower left leaning rotating shaft LDL are offset in the horizontal direction of a vehicle body frame 21 from a left steering rotating shaft SL when viewed from the cross direction of the vehicle body frame 21, and an upper right leaning rotating shaft LUR and a lower right leaning rotating shaft LDR are offset in the horizontal direction of the vehicle body frame 21 from a right steering rotating shaft SR when viewed from the cross direction of the vehicle body frame 21. A straight line connecting the upper left leaning rotating shaft LUL with the lower left leaning rotating shaft LDL is overlapped with a ground surface 31a of a left front wheel 31 when viewed from the cross direction of the vehicle body frame 21, and a straight line connecting the upper right leaning rotating shaft LUR with the lower right leaning rotating shaft LDR is overlapped with a ground surface 32a of a right front wheel 32 when viewed from the cross direction of the vehicle body frame 21.SELECTED DRAWING: Figure 9

    【課題】リーン車両のトレッド幅を変更可能にする。【解決手段】第一サイド部材11と第二サイド部材12の位置を入れ替えることで、トレッド幅が相違する第一状態と第二状態のいずれかが選択され、以下条件が成立する。上左リーニング回動軸LULと下左リーニング回動軸LDLは車体フレーム21の前後方向から見て左ステアリング回動軸SLから車体フレーム21の左右方向に、上右リーニング回動軸LURと下右リーニング回動軸LDRは車体フレーム21の前後方向から見て右ステアリング回動軸SRから車体フレーム21の左右方向にオフセットしている。上左リーニング回動軸LULと下左リーニング回動軸LDLを結ぶ直線は、車体フレーム21の前後方向から見て左前輪31の接地面31aと、上右リーニング回動軸LURと下右リーニング回動軸LDRを結ぶ直線は、車体フレーム21の前後方向から見て右前輪32の接地面32aと重なっている。【選択図】図9
