A pair of reinforcing stays 5 are provided approximately at the center of the
A pair of seat trays 3 are provided rearward from a joint 6 between the center pillar 3 and the reinforcing stay 5, and an engine support member 8 is vertically provided below. In addition, 9 is a back stay that connects the approximate center part of the seat rail 7 and the lower part of the center pillar 3.
IO is a horizontal rod that connects the left and right main frames 21.
