VEHICLE BODY FRAME FOR A SADDLE TYPE VEHICLE A main frame attachment portion (44) to which a main frame (20) is welded is provided on a head pipe (11) formed by forging, and the main frame attachment portion (44) and a lower extension (45) extending downwardly from a pipe portion (40) are provided integrally with each other. A down frame attachment portion (50) is provided at a position of a lower portion of the lower extension (45) spaced from the main frame attachment portion (44) and the pipe portion (40), and the down frame (21) is welded at an upper end portion thereof to the down frame attachment portion (50). The down frame attachment portion (50) is configured from a connecting portion (54) extending in parallel to the pipe portion and an extension (55) extending rearwardly from a lower end portion of the connecting portion (54). The down frame (21) is welded only by contacting the same without inserting the same. By eliminating the insertion shape, reduction of the cost is implemented, and by disposing the down frame (21) in a spaced relationship from the main frame attachment portion (44) and the pipe portion (40) to which a high load is applied, the welding quality is improved. 11, A4 xA AxAD II) ~51 54 \ 121a \4 3b 52\\( 'N12 \\ \c 5
