Claims

[Scope of utility model registration request]

The front wheel is configured to transmit power from the front wheel drive shaft 33 inserted through the front axle housing 31 to the front axle 32 via the king pin 36, thereby enabling power transmission regardless of the steering rotation of the front axle 32. Axle 3
2, a drive pinion that pivotally supports an intermediate shaft 39 in parallel with the front axle 32, transmits power to the front axle 32 via the same shaft 39, and meshes with the outer end of the intermediate shaft 39 and the inner end of the front axle 32; 40 and a driven gear 41, and a front axle case 45 which pivotally supports a front axle 32 is mounted rotatably and fixedly around an intermediate shaft 39, in a vehicle height changeable.
