ABSTRACT:
Ends of each supporting pin are projected to both sides of each link plate. Each supporting shaft is fixed by welding to each link plate at a position near one end side of the plate. A pipe-like connecting shaft is axis-aligned to and fitted on an end portion of the supporting pin which projects inward from each link plate, so as to be supported between link plates. An end portion of the supporting pin which projects outward from each link plate is passed through a side frame section and fixedly riveted over. Further, each link plate is fixed by welding to both ends of the connecting shaft, and a link base frame is assembled between side frame sections.
