To achieve downsizing of a cover member provided at a power transmission shaft.SOLUTION: A support device 5 supports a shaft member 1A which transmits rotational force of a driving source of a vehicle to driving wheels and has: an insulator 26; a bearing 27; and a first cover member 28 located at one side of the bearing 27. The insulator 26 has: an insulator body part 26A formed into an annular shape by an elastic material; a first core grid 26B located between the insulator body part 26A and the bearing 27; and a second core grid 26C located at the outer periphery side of the insulator body part 26A. In the first cover member 28, an outer diameter D28 is formed smaller than an inner diameter D26C of the second core grid.SELECTED DRAWING: Figure 2 【課題】本発明の目的は、動力伝達軸に設けられるカバー部材の小型化を実現することにある。【解決手段】車両の駆動源の回転力を駆動輪に伝達するシャフト部材１Ａを支持する支持装置５は、インシュレータ２６と、軸受２７と、軸受２７の一方側に位置する第１カバー部材２８と、を有する。インシュレータ２６は、弾性材料で環状に形成されるインシュレータ本体部２６Ａと、インシュレータ本体部２６Ａと軸受２７との間に位置する第１芯金２６Ｂと、インシュレータ本体部２６Ａの外周側に位置する第２芯金２６Ｃと、を有する。第１カバー部材２８は、外径Ｄ２８が、第２芯金の内径Ｄ２６Ｃよりも小さく形成されている。【選択図】図２
