PROBLEM TO BE SOLVED: To provide a vibration control structure which suppresses torque variation caused by gear change and drive reaction force to downsize a power unit and can reduce vibration generated on the power unit.SOLUTION: In a power unit (P) in which an internal combustion engine (E) is provided with transmissions (Tm, Ts), a vibration control structure of the power unit has torque dampers (60, 57a, 57b, 58a, 58b) between speed change gears (53, 54) of the transmission (Ts) and a power transmission shaft (51) rotationally supporting the speed change gears (53, 54). 【課題】変速や駆動反力に伴うトルク変動自体を小さく抑えてパワーユニットを小型化するとともに、パワーユニットの振動を可及的に低減することができるパワーユニットの防振構造を供する。【解決手段】内燃機関(E)に変速機(Tm,Ts)が備えられたパワーユニット(P)において、変速機(Ts)の変速歯車(53,54)と同変速歯車(53,54)を軸支する動力伝達軸(51)との間にトルクダンパ(60,57a,57b,58a,58b)が設けられたパワーユニットの防振構造。【選択図】図６
