CONSTITUTION:The axle shaft 5 of a drive axle with a steering device is supported by a bearing 7 at the axle end 9, and a spherical section 1 is integrally formed on the axle end 9. A knuckle 2 is supported by this spherical section 1 via king pins 4, and an axle case 20 is fitted to the knuckle 2 with bolts 22. In this case, a seal 3 made of ring-shaped rubber, felt, etc. and fitted to the knuckle 2 is brought into contact with this spherical section 1. This seal 3 is arranged slantly and intersectionally astride king pin bearings 19 pivotally supporting the upper and lower king pins 4, 4.
