PROBLEM TO BE SOLVED: To surely weld both end parts of a cross pipe to the internal walls of main frames by absorbing a dimension between a pair of the right and left main frames or an error of a length in the axial direction of the cross pipe in the body frame of a motorcycle equipped with a head pipe having a cylindrical section by which a front fork axially supporting a front wheel is supported in a manner to be steerable, a pair of the right and left main frames which are connected to the head pipe and extend down-backward, and the cross pipe which bridges the front sections of both main frames. SOLUTION: On the internal walls of both main frames 23, an attaching hole 32 is coaxially provided. Both end parts of the cross pipe 27 which is passed through the attaching holes 32 is welded to the internal walls of both main frames 23. COPYRIGHT: (C)2005,JPO&NCIPI
