PROBLEM TO BE SOLVED: To achieve smooth vibration absorption and improvement of rigidity, and reduce cost.SOLUTION: A swing type power unit suspension mechanism 5 comprises: a first link 53 which is coupled so as to vibrate freely, to a bolt 58 which is a frame pivot shaft of a vehicle body frame 11 through a radial bearing 61; and a second link 54 which is coupled so as to vibrate freely to the first link 53 and the power unit 131. The second link 54 further comprises: a set of two link members 55 whose one end parts are coupled so as to vibrate freely to the first link 53 through a radial bearing 62, whose the other end parts are coupled so as to vibrate freely to the power unit 131 through a radial bearing 63, and being disposed in parallel; and a vibration control member 56 which can be elastically deformed and disposed over the set of two link members 55.

    【課題】スムーズな振動吸収と剛性の向上を図りつつ、コストの削減を図る。【解決手段】スイング式パワーユニットの懸架機構5は、車体フレーム11のフレームピボット軸であるボルト58にラジアルベアリング61を介して揺動可能に連結される第1リンク53と、第1リンク53とパワーユニット131に揺動可能に連結される第2リンク54とを有し、第2リンク54は、さらに、一端部が第1リンク53にラジアルベアリング62を介して揺動可能に連結され、他端部がパワーユニット131にラジアルベアリング63を介して揺動可能に連結され、互いに平行に設けられる組をなす2個のリンク部材55と、組をなす2個のリンク部材55の間に跨って設けられる弾性変形可能な防振部材56とを有する。【選択図】図3
