ABSTRACT:
A left fore leg (31) is formed to shape by a casting means, integrating an inner joint portion (31A), an outer joint portion (31B) and an intermediate tubular portion (31C) into an unitary tubular structure. In this case, a joining end (31A1) of the inner joint portion (31A) as well as an outer joining end (31B1) of the outer joint portion (31B) is in the form of an open end of a rectangular shape. Accordingly, it becomes possible to cut the production cost of truck frame (11) and to form a longer welding bead around the outer periphery of the respective inner and outer joining ends (31A1) and (31B1) to enhance the joint strength between the inner joint portion (31A) and a center frame (12) as well as the joint strength between the outer joint portion (31B) and a side frame (22).
