PURPOSE:To improve strength for external force given from the outside, make maintenance easy and prevent contact with a radiator during guard transformation by overlapping a radiator guard on the front side of a body frame and positioning the radiator and the radiator guard in a front-and-back ubiquitous relation, as viewed from the side. CONSTITUTION:A circular metal-pipe radiator guard 53 is provided so as to be projected from a front-tube 12 constituting a down-tube 11 to the outside of a body and bent in a U shape as viewed from the side to form a vertical pipe 53a and upper and lower pipes 53a, 53c inwardly in width, and supported to the front-tube 12 and a reinforcing frame using bolts 54, 55. On the other hand, a radiator 48 is arranged on the front side of the front-tube 12 and guarded at the side outer-edge by a guard 53. In this way, the vertical pipe 53a is superposed on the front-tube 12 in parallel and so improved in resistance under external force. Also, the radiator 48 is in front of the guard 53 and so made in size almost equal to the guard to improve its performance. |
