【発明の詳細な説明】 ［産業上の利用分野］ この発明は、燃料タンクを車体フレームに後方に傾倒可
能に設ける自動二輪車の燃料タンク取付装置に関する。Description: TECHNICAL FIELD The present invention relates to a fuel tank mounting device for a motorcycle in which a fuel tank is provided in a vehicle body frame so as to be tiltable rearward.

ボルトとナットにより車体フレームのブラケットに着脱
可能に取り付けたものがある。[Prior Art] In a motorcycle, a fuel tank is usually arranged above the engine so as to straddle the body frame. In this type of fuel tank, for example, as disclosed in Japanese Utility Model Laid-Open No. 58-43575, a stay is provided at the rear portion of the fuel tank, and the stay is rotated around a pivot shaft attached to a vehicle body frame via a rubber bush. There is one in which the fuel tank is movably supported, and a bracket is provided on the front part of the fuel tank, and the bracket is detachably attached to the bracket of the vehicle body frame with bolts and nuts.

部のボルトとナットを外すことで、後部のピボット軸を
支点として回動させて後方に傾倒することができ、これ
によりエンジン上方が開放され、上からの修理点検作業
が容易にできる利点がある。When repairing and inspecting the engine, etc., this fuel tank can be rotated around the pivot shaft of the rear part as a fulcrum and tilted rearward by removing the bolts and nuts on the front part. Therefore, there is an advantage that repair and inspection work can be easily performed from above.
［発明が解決しようとする課題］ ところで、燃料タンクの傾倒で、燃料タンクの後部に設
けたステーの回動と共にラバーブッシュが回動し、ラバ
ーブッシュの姿勢が変化して荷重の加わる方向が定まら
ないため、ラバーブッシュの荷重設計が難しく、ラバー
ブッシュが長期の使用に耐えないという不具合がある。[Problems to be Solved by the Invention] By the way, when the fuel tank is tilted, the rubber bush is rotated along with the rotation of the stay provided at the rear portion of the fuel tank, and the posture of the rubber bush is changed to determine the direction in which the load is applied. Since there is no rubber bush, it is difficult to design the load of the rubber bush, and there is a problem that the rubber bush cannot withstand long-term use.
また、燃料タンクの前部はブラケットを燃料タンクの下
面近傍に直接固定し、しかもこのブラケットを車体フレ
ームのブラケットに着脱可能に取り付ける構造であるた
め、車体の振動が燃料タンクの前部に着接伝達され、燃
料タンクの前部の振動が大きくなる。Further, since the front portion of the fuel tank has a structure in which a bracket is directly fixed near the lower surface of the fuel tank and the bracket is detachably attached to the bracket of the vehicle body frame, vibration of the vehicle body contacts the front portion of the fuel tank. As a result, the vibration at the front of the fuel tank is increased.
このため、例えば車体フレームに弾性部材を介してブラ

して設けたブラケットが残り、修理点検作業のときに邪
魔になる。Therefore, for example, it is considered that a bracket is provided on the vehicle body frame via an elastic member and the bracket at the front portion of the fuel tank is attachable to and detachable from the bracket to reduce the vibration of the fuel tank. In the structure in which the elastic member is installed between the frame and the frame, when the fuel tank is tilted rearward, the bracket provided on the body frame side via the elastic member remains, which becomes an obstacle during repair and inspection work.
さらに、燃料タンクの前部のブラケットが燃料タンクの

る。Furthermore, since the bracket at the front of the fuel tank projects a lot from the bottom of the fuel tank to the front side and is provided near the lower surface, when the fuel tank is tilted rearward, the bracket is provided around the head pipe, for example. It is necessary to consider not to interfere with other parts such as brackets.

取付装置を提供することを目的としている。The present invention has been made in view of such circumstances, suppresses the vibration of the fuel tank, and further, the elastic member withstands long-term use even when the fuel tank is tilted, and the front mounting stay of the fuel tank is tilted when the fuel tank is tilted. An object of the present invention is to provide a fuel tank mounting device for a motorcycle that does not need to consider interference with other parts and that does not interfere with repair and inspection work even though it is supported via an elastic member.

能に構成したことを特徴としている。[Means for Solving the Problems] In order to solve the above problems, in a fuel tank mounting device for a motorcycle of the present invention, a rear side of a fuel tank is supported by a vehicle body frame via a rear elastic member. The bracket is rotatably supported, and on the other hand, the front part of the fuel tank is provided with a recess near the upper surface, and the front mounting stay is supported in this recess via a front elastic member. The fuel tank is detachably attached to the vehicle body and the front side stay and the vehicle body stay are disengaged from each other so that the fuel tank can be tilted rearward with the rear side bracket as a fulcrum.

えられる。[Operation] In the present invention, the rear portion of the fuel tank is rotatably supported by the rear mounting bracket supported by the vehicle body frame via the rear elastic member, while the front portion of the fuel tank is interposed by the front elastic member. The front attachment stay is supported by the front attachment stay, and the front attachment stay is detachably attached to the vehicle body frame. Vibration of the fuel tank is suppressed by the rear elastic member and the front elastic member.

に考慮する必要がない。Further, a recess 10c is formed in the front portion B of the fuel tank 8, and the front mounting stay 22 is supported in the recess 10c via front elastic members 23 and 24. Since the stay 22 has a small protruding amount and the front mounting stay 22 is supported in the vicinity of the upper surface of the front portion B of the fuel tank 8, the front mounting stay 22 is supported by, for example, a head pipe when the fuel tank 8 is tilted rearward. It is not necessary to consider so as not to interfere with other parts such as a reinforcing bracket (not shown) provided around.
