PROBLEM TO BE SOLVED: To provide a support structure of a unit swing type drive unit which effectively absorbs beat vibration in which change periodically occurs in a vibrational amplitude.SOLUTION: In a support structure 27 of a unit swing type drive unit, an intermediate shaft is provided at link arms 89a, 89b which are connected to a vehicle body 12 by a first pivot shaft 87, pivotally supported on a drive unit 25 by a second pivot shaft 88 so as to swing, and separated in a lateral direction. The link arms 89a, 89b are elastically supported on the vehicle body 12 by rubber bushes 114. Further, contact members 116, each of which enables the vehicle body 12 and the link arms 89a, 89b to rigidly contact with each other, are disposed at both ends of the first pivot shaft 87.SELECTED DRAWING: Figure 6

    【課題】周期的に振動振幅に変化が生じるうなり振動を効果的に吸収することができるユニットスイング式駆動ユニットの支持構造を提供する【解決手段】ユニットスイング式駆動ユニットの支持構造27は、第1ピボット軸87で車体12に連結され、第2ピボット軸88で駆動ユニット25に搖動可能に枢支されて左右方向に離間するリンクアーム89a、89bに中間軸を設け、車体12にリンクアーム89a、89bをラバーブッシュ114で弾性支持するとともに、第1ピボット軸87の両端に、車体12とリンクアーム89a、89bとを剛に当接可能な当接部材116を配置した。【選択図】図6
