ボルトで共締めすることにより、エンジンを強度部材と
して利用したものが知られている。In a frame in which a bracket member for pivotally supporting the rear arm is connected to the rear end of the left and right main frame members connected to the steering head pipe, a boss part protruding from the engine crankcase has conventionally been installed between the left and right bracket members. It is known that the engine is used as a strength member by interposing the boss part and the bracket member and tightening them together with bolts.
ところが、上記ブラケット部材は、それ自体が高剛性に

等の問題があった。However, in addition to being made with high rigidity, the bracket members themselves are connected to each other via cross members, so even if the through bolts are tightened, the bracket members hardly bend inward. First, it was difficult to effectively tighten the boss portion. For this reason, a gap may be created between the boss portion and the bracket member, resulting in problems such as the engine not being able to be used effectively as a strength member.
そこで、本発明においては、左右のブラケット部材とエ

とを特徴とする。Therefore, in the present invention, when the left and right bracket members and the boss part of the engine are fastened together with a through bolt, the outer periphery of the through bolt comes into contact with the end face of the boss part as the through bolt is tightened. In addition to providing a pressing part,
At least one of the bracket members is provided with an insertion hole into which the pressing part is movably inserted in the axial direction, and the bracket member is provided with a slit whose one end opens into the inner circumferential surface of the insertion hole, The present invention is characterized in that a screw member is screwed in to reduce the diameter of the insertion hole by narrowing the groove width of the slit.
この構成によれば、ねじ部材を緩めた状態では、通しボ

付は力をボス部に有効に伝えることができる。According to this configuration, when the screw member is loosened, the pressing part on the outer periphery of the through bolt is movable in the axial direction of the through bolt with respect to the bracket member. portion comes into contact with the end surface of the boss portion, and the boss portion can be firmly tightened between the pressing portions or between the pressing portion and the bracket member on the opposite side without a gap. Therefore, even if the bracket member has high rigidity, force can be effectively transmitted to the boss portion by tightening the through bolt.
そして、この締付は後にねじ部材をねじ込んで、挿通孔

を強度部材の一部として有効に利用できる。This tightening can be done later by screwing in a screw member to reduce the diameter of the insertion hole, and since the pressing part is fixed on the inner peripheral surface of the insertion hole, the tightening of the boss part can be done without changing the state. It can be maintained as is. Therefore, the boss portion can be firmly positioned and fixed between the bracket members, and the engine can be effectively used as a part of the strength member.

スペーサ２４に伝えることができる。Therefore, in the case of this configuration, the other end of the slit 28 is closed within the extension portion 27 without opening to the outer peripheral lower surface of the bracket member 5, so when the bolt 30 is tightened, the slit 28 is closed. The groove width is reduced substantially uniformly over the entire area. Therefore, the slit 28 is not locally deformed, and the tightening force of the bolt 30 can be transmitted to the spacer 24 more reliably.
さらに、本発明を実施するに当たっては、通しボルトの
挿通端側に位置するボルト挿通孔にめねじ部を形成して
