PROBLEM TO BE SOLVED: To provide a support structure of a drive axle capable of enhancing an effect of loosening stop while preventing an increase in weight or an increase in the number of assembling processes.SOLUTION: A support structure of a drive axle is such that a power transmission mechanism (A), which transmits power of a power source, and driving wheels (WR) are fixed to a drive axle (70) which is rotatably supported by a support part (53) included in a vehicle (1). Herein, a female screw (78) is formed on an internal surface of a hollow formed at an end of the drive axle (70). By tightening a bolt (60) to be engaged with the female screw (78), the power transmission mechanism (A) is fixed to the drive axle (70). A step (76) is formed between a small-diameter part (71) and a large-diameter part (72) formed on a periphery of the drive axle (70). Owing to the step (76), the position in an axial direction of the power transmission mechanism (A) fixed to the small-diameter part (71) is restricted.SELECTED DRAWING: Figure 5

    【課題】重量増や組み立て工程の増加を防ぎつつ緩み止め効果を高めることができる駆動軸の支持構造を提供する。【解決手段】車両(1)に設けられる支持部(53)に回転可能に軸支される駆動軸(70)に対して、動力源の動力を伝達する動力伝達機構(A)と駆動輪(WR)とを固定するようにした駆動軸の支持構造において、駆動軸(70)の端部に形成された中空部の内周面に雌ねじ部(78)を形成する。雌ねじ部(78)に螺合するボルト(60)を締め付けることで、動力伝達機構(A)が駆動軸(70)に固定される。駆動軸(70)の外周面に形成される小径部(71)と大径部(72)との間に段差(76)を設ける。段差(76)によって、小径部(71)側に固定される動力伝達機構(A)の軸方向位置を規制する。【選択図】図5
