To ensure degree of freedom of shock absorber layout while suppressing increase in friction at a connection part with a vehicle body frame.SOLUTION: A rear suspension device 40 for a two-wheeled motor vehicle elastically supports a swing arm 5 for a rear wheel to a vehicle body frame 6 by a shock absorber 41 and a linkage 42. The linkage 42 comprises: a first link member 50 which connects a lower end part of the shock absorber 41 and the swing arm 5; and a second link member 60 which connects the first link member 50 and the vehicle body frame 6. The second link member 60 comprises: a pair of left and right arm parts 70 which connect the first link member 50 and the vehicle body 6 and extend along in a vehicle longitudinal direction; and a horizontal part 80 which connects the pair of left and right arm parts 70 with each other halfway between a front end part and a rear end part of the arm part 70 and extends along a vehicle width direction.SELECTED DRAWING: Figure 2

    【課題】車体フレームとの連結部でのフリクションの増加を抑制しつつ、ショックアブソーバのレイアウトの自由度を確保する。【解決手段】自動二輪車のリヤサスペンション装置40は、ショックアブソーバ41及びリンク機構42により後輪用のスイングアーム5を車体フレーム6に弾性的に支持する。リンク機構42は、ショックアブソーバ41の下端部とスイングアーム5とを連結する第1リンク部材50と、第1リンク部材50と車体フレーム6とを連結する第2リンク部材60と、を備える。第2リンク部材60は、第1リンク部材50と車体フレーム6とを繋ぎ且つ車両前後方向に沿うように延びる左右一対のアーム部70と、左右一対のアーム部70同士をアーム部70の前端部と後端部との間の途中で繋ぎ且つ車幅方向に沿うように延びる横架部80と、を備える。【選択図】図2
