PROBLEM TO BE SOLVED: To make vibration attenuation ability of a damper provided on a power transmission system of a sub drive wheel side proper.SOLUTION: A power transmission system from a drive source 6 to a sub drive wheel 4 comprises: a damper 80; a first rotation member 45 connected to a drive source side; and a second rotation member 46 connected to a sub drive wheel side. The damper 80 has a first cylindrical part 82 connected to the first rotation member 45, a second cylindrical part 84 connected to the second rotation member 46, and an elastic body layer 90 arranged between the first cylindrical part 82 and the second cylindrical part 84. The elastic body layer 90 has a first elastic part 91 which is compressed and deformed when the first cylindrical part 82 is displaced to a downstream side relatively to the second cylindrical part 84 in a rotation direction F1 in forward traveling time, and a second elastic part 92 which is compressed and deformed when the first cylindrical part 82 is displaced to an upstream side relatively to the second cylindrical part 84 in the rotation direction F1, in which vibration attenuation ability of the first elastic part 91 is higher than that of the second elastic part 92.SELECTED DRAWING: Figure 5
【課題】副駆動輪側の動力伝達系に設けられるダンパの振動減衰能力の適正化を図る。【解決手段】駆動源6から副駆動輪4までの動力伝達系に、ダンパ80、その駆動源側に連結された第1回転部材45、及び、副駆動輪側に連結された第2回転部材46が設けられ、ダンパ80は、第1回転部材45に連結された第1筒部82、第2回転部材46に連結された第2筒部84、及び、第1筒部82と第2筒部84との間に配置された弾性体層90を備え、弾性体層90は、前進走行時の回転方向F1において第1筒部82が第2筒部84に対して相対的に下流側に変位したときに圧縮変形される第1弾性部91と、前記回転方向F1において第1筒部82が第2筒部84に対して相対的に上流側に変位したときに圧縮変形される第2弾性部92とを有し、第1弾性部91の振動減衰能力が第2弾性部92の振動減衰能力よりも高い車両のトランスファ構造を提供する。【選択図】図5
