のため弾性部材の固有振動数を前記のように設定しても
所期の振動遮断効果が得られないという問題がある。In this type of motorcycle, in order to prevent the vertical vibration of the engine from propagating to the frame, it is necessary to set the natural frequency of the elastic member to a value less than 1 relative to the frequency of the engine when it is idle. However, there is a problem in that the engine is pulled backwards due to the tension of the drive chain during driving, so even if the natural frequency of the elastic member is set as described above, the desired vibration isolation effect cannot be obtained. be.

に確実に行うことができる。As described above, according to the present invention, both ends of the non-stretchable flexible member extending substantially parallel to the suspension direction of the drive chain 7 are fixed to at least the front part of the engine and the frame opposite thereto. Therefore, the flexible member prevents the engine from being pulled rearward by the tension of the drive chain, and the flexible member and the elastic member work together to absorb vertical vibrations of the engine. Propagation of vibration to the frame can be blocked. Furthermore, by preventing the engine from moving, the drive chain can be prevented from slackening, and the drive force can always be transmitted reliably.
