The generation of a casting defect is suppressed which would otherwise occur to frame members of a seat frame when being formed of a magnesium alloy or an aluminum alloy by casting. The seat frame (100) according to the present invention is for a saddle-riding type transporter (200), and includes a pair of frame members (10L,10R) formed of a magnesium alloy or an aluminum alloy by casting. The pair of frame members (10L,10R) each include a first side wall (11), a second side wall (12) located outer with respect to the first side wall (11) in a vehicle width direction (B), and a connecting wall (13) for connecting the first side wall (11) and the second side wall (12) to each other. The connecting wall (13) includes seat fixing section (13a,13b,13c) for fixing a seat (136,139). The pair of frame members (10L,10R) each include a first region (R1) in which a top end of the first side wall (11) and a top end of the second side wall (12) are connected to each other by the connecting wall (13), and a second region (R2) in which a portion below the top end of the first side wall (11) and a portion below the top end of the second side wall (12) are connected to each other by the connecting wall (13).
