前記ピボットフレームの前記下部は、前記サイドスタンドブラケットの近傍において、前記ロアフレームにのみ連結されるフレーム固定部を備えることを特徴とする。
前記凹部に、前記サイドスタンドブラケットが取り付けられていることを特徴とする。
サイドスタンドブラケット11は、例えば鍛造にて成形された金属の板材から構成されており、図4に示すように、側面視において、略三角形状の基部11tの下端部に前方側へ延出する前方延出部11fが設けられ、基部11tの略中央部に後方側へ延出する後方延出部11rが設けられている。また、基部11tの下端部には、サイドスタンド10を回転可能に保持する取付用孔11dhを有するサイドスタンド取付部11dがサイドスタンド10を立てた時に所望の傾斜角度にて支持できるように下端側に向かって車両外側に傾斜して設けられている。即ち、前方延出部11fは、基部11tの下端部からサイドスタンド取付部11dよりも前方へ延出している。基部11tの略中央部には第1固定用孔11ahを有する第1固定部11aが設けられており、後方延出部11rには係止用孔11ghが穿設されている。また、基部11tの上端部及び前方延出部11fには第2固定用孔11bhを有する第2固定部11bがそれぞれ設けられている。詳しくは後述するが、第1固定部11aはピボットフレーム5にのみ連結され、第2固定部11bはメインステップブラケット21にのみ連結される。また、基部11tには、第1固定部11aの下方に車両内側に突出(図5参照)するピン部材11pが設けられている。
また、サイドスタンドブラケット11の形状およびメインステップブラケット21の形状についても適宜変更可能であり、また、締結ボルトの本数についても上記実施態に何ら制限されるものではない。
また、上記実施形態においては、自動二輪車について説明したが、本発明は、車輪の数に関わらず、サイドスタンドを要する鞍乗型車両に適用できる。
