Zusammenfassung:	To prevent a phenomenon in which a bolt and a bush corotate when the bolt is fastened, in regard to a bolt fastening structure for making first and second members connected to each other by passing through a first member through-hole and a second member through-hole.SOLUTION: A bush 32 comprises: a cylindrical part 33 which has a central hole 37 subjected to insertion of a bolt and which is inserted into a first member through-hole 26; a flange part 34 which is integrally provided at one end of the cylindrical part 33 and which is locked to a first member; and a plurality of protrusions 36 which are provided on a contact surface 35 of the flange part 34 and which bite into the first member.SELECTED DRAWING: Figure 3 【課題】第１部材貫通孔および第２部材貫通孔に通されてこれら第１部材および第２部材を互いに結合するボルト締結構造に関し、ボルト締結時にボルトとブッシュが共回りする現象を防止する。【解決手段】ブッシュ３２は、ボルトが通される中心孔３７を有し第１部材貫通孔２６に差し込まれる円筒部３３と、円筒部３３の一端に一体に設けられて第１部材に係止する鍔部３４と、鍔部３４の接触面３５に設けられて第１部材に食い込む複数の凸部３６とを備える。【選択図】図３
