PROBLEM TO BE SOLVED: To improve power transmission feeling in a power transmission mechanism including a drive shaft and form the power transmission mechanism compactly in a vehicle width direction.SOLUTION: A power transmission mechanism includes: a drive shaft 22 which transmits power from an engine 11; a bevel gear 35 provided at a rear part of the drive shaft 22; a ring gear 50 which meshes with the bevel gear 35 and is coaxially provided with rear wheels 3; a rear wheel axle 47 coupled to the ring gear 50; and a gear case 24 which houses at least the ring gear 50 and the bevel gear 35. In the power transmission mechanism, a damper mechanism 36 is provided on a power transmission path between a shaft body 31 of the drive shaft 22 and the bevel gear 35. The damper mechanism 36 is housed in the gear case 24. 【課題】ドライブシャフトを備えた動力伝達機構において、動力の伝達フィーリングを向上させるとともに、動力伝達機構を車幅方向にコンパクトに構成できるようにする。【解決手段】エンジン１１からの動力を伝達するドライブシャフト２２と、ドライブシャフト２２の後部に設けられるベベルギア３５と、ベベルギア３５に噛み合うとともに後輪３と同軸に設けられるリングギア５０と、リングギア５０に結合する後輪車軸４７と、少なくともリングギア５０及びベベルギア３５を収容するギアケース２４とを備える動力伝達機構において、ドライブシャフト２２のシャフト本体３１とベベルギア３５との動力伝達経路上にダンパ機構３６が設けられ、ダンパ機構３６は、ギアケース２４内に収容される。【選択図】図２
