Abstract

PURPOSE:To easily adjust a vehicle height in a wheel supporting structure in an agricultural tractor or the like, by pivotably mounting a wheel supporting knuckle to an arm vertically swingably pivoted to a body, and interchangeably engaging the knuckle with a plurality of mounting holes of a knuckle holder. CONSTITUTION:Upper and lower brackets 31 and 32 are projected from an inside surface of a reduction case 26. A knuckle 35 is relatively rotatably connected through king pins 33 and 34 to the brackets 31 and 32. A knuckle arm 37 is fixed to the upper bracket 31. The knuckle arm 37 is pivotably connected through a tie rod 38 to a front end of a link mechanism 91. An upper arm 39 is pivotably mounted to an upper portion of the knuckle in such a manner as to be relatively swingable in vertical direction. Right and left knuckle holders 50 are fixed to a differential case 20, and are formed with vertically arranged mounting holes 63-65 to which the knuckle 35 is bolted. Thus, adjustment of a vehicle height may be easily carried out by changing a bolted position of the mounting holes.
