PROBLEM TO BE SOLVED: To provide a frame structure of a motor cycle which effectively achieves proper vehicle body rigidity balance, reduction of the number of components, weight reduction, and cost reduction etc.SOLUTION: A frame structure of a motor cycle comprises: a pair of left and right main frames 11 which extends from a head pipe 101 to the rear side while expanding its width; and a pivot frame 12 welded to the main frames 11 and extending to the rear lower side. An engine 121 is disposed below the main frames 11. Hanging parts for holding and fastening the engine 121 are provided in the main frames 11. An expansion part 13 is provided at the vehicle width direction outer side of a front part of each main frame 11, and the hanging parts may be set at the expansion part 13.SELECTED DRAWING: Figure 2

    【課題】車体剛性バランスの適正化、部品点数削減、軽量化及びコスト低減等を有効に実現する自動二輪車のフレーム構造を提供する。【解決手段】ヘッドパイプ101から後方に向かって拡幅しながら延出する左右一対のメインフレーム11と、メインフレーム11に溶着され後下方に向かって延びるピボットフレーム12で構成され、メインフレーム11の下方にエンジン121が配置される。メインフレーム11にエンジン121を保持締結するための垂下部が設けられる。メインフレーム11の前部に車幅方向外側に膨出部13を設け、膨出部13に垂下部を設定可能にする。【選択図】図2
