PROBLEM TO BE SOLVED: To provide a trunnion type suspension structure which eliminates positional limitations on a point where a trunnion bracket is fastened by an upper gusset and thereby realizes effective force transmission.SOLUTION: A cutout recessed part 51c which may engage with an upper surface of a cross member 10 and places a reinforcement lateral plate part 51a in contact with the upper surface of the cross member 10 is formed at a reinforcement vertical plate part 51b which extends so as to be suspended from one end edge of the reinforcement lateral plate part 51a of an upper gusset 51 and is attached to an upper part of an inner surface of a web 5a in a frame 5. This structure allows the upper gusset 51 to be attached in a later process. |
