PROBLEM TO BE SOLVED: To secure rigidity of a continuously extending frame constituting part and suppress an increase of the size of a connecting part between a frame main body and a sub frame, also when providing the connecting part in a longitudinal direction intermediate part of the frame constituting part, in a vehicle body frame structure of a saddle ride type vehicle making a part of a vehicle body frame as the sub frame attachable/detachable to/from the frame main body. SOLUTION: A frame main body side fastening part 42 and a sub frame side fastening part 52 are formed to vertically divide a part of the frame constituting part by the connecting part. A distal end side outer periphery of each of the fastening parts 42 and 52 is cut to avoid the fastening positions. Standing walls 48 and 58 corresponding to the cut parts are integrally formed on a base end side of the other fastening part. The distal end sides of the fastening parts 42 and 52 are fitted into recessed parts 49 and 59 surrounded by the standing walls 48 and 58 to be mutually fastened. COPYRIGHT: (C)2009,JPO&INPIT
