PROBLEM TO BE SOLVED: To alleviate a burden to a rider when the rider moves forward at high speed. SOLUTION: A frame structure 10 is equipped with a handlebar 20 for steering a front wheel by the rider, an upper frame 42 for supporting the handlebar 20 so as to be turnable by a forward upper turning support 60, and a lower frame 44 for supporting the front wheel 16 so as to be turnable by a forward lower turning support 76. The rear part of the upper frame 42 and the rear part of the lower frame 44 are connected by an engine front frame 46 with each other. The rear part of the upper frame 42 is connected to the engine front frame 46 through a press-fit buffering mechanism 58. The upper frame 42 has a cushion 66 for covering almost all surfaces of rear side surface of the upper frame 42. COPYRIGHT: (C)2009,JPO&INPIT
