Abstract

PURPOSE:To prevent the generation of welding strain without making any bearing part separately by providing projected parts at proper intervals on the lower edge of a main board of a side drop door in a dump truck or the like, and bending these projected parts to make a bearing part. CONSTITUTION:On the lower edge of a main board 2 of a side drop door 1 for a dump truck, projected parts 3 are provided at proper intervals and bent inward to form a bearing part 4. Brackets 8, 8' are fixed on a Z-shaped side plate 6 fixed on the outer edged of a floor board 5, and the bearing part 4 is set between these brackets 8, 8' to be smoothly rotated around a central shaft 9. In this construction, the bearing part 4 is made in one body, and free from separate manufacturing and welding for preventing the generation of strain.
