PURPOSE:To prevent a crack from occurring at a fitting section and prevent the disk buffer action from being diminished by removably fitting a weight to a wheel shaft outer end section in a wheel load increasing device to increase the tractive force of a tractor, etc. CONSTITUTION:A weight 6 is removably fitted with a fitting bolt 8 to a disk 3 fitted to the outer end section 2 of a wheel shaft 1. At this time, the disk 3 is tightened to the outer end section 2 at the vicinity of its center with a fitting bolt 8 and nut 11, and the disk 3 is fixed in conjunction with a fitting bolt 4. Thereby, the settling and crack of a bolt hole can be prevented. In addition, a disk 3 base section is pressed to the outer end section 2 of the wheel shaft 1 with a fitting seat 5 to increase the fitting area, thus a crack, etc. can e prevented and the disk buffer action can be prevented from being diminished. |
