A guide recess 7, which is a guide section A, is provided in the lower part of the vehicle body frame 1 configured as described above. That is, a hole 9 is formed in the overlapping portion 8 of the engine hanger bracket 6 and the floor panel 5, and a concave member 10 is fixed to the floor panel 5 so as to cover the hole 9. The guide recess 7 is formed by the hole 9 and the recess 10.
is formed.

The engine hanger bracket 6 is provided with a pair of bracket parts 11.
1 is provided with a connecting hole 11a.

The rear vehicle body 45 and the stand mechanism 44 are provided with a stand hanger 12, and the stand hanger 12 is provided with a stand 13 which is in contact with a stopper 12a in a grounded state and whose forward rotation is restricted. 14 is a return spring that returns the stand 13 to the folded state. The stand hanger 12 is swingably connected to the case 17 of the power unit 42 by a pin 16 above the middle portion thereof. Stand hanger 12 of stand mechanism 44
An anti-vibration link mechanism C is provided at the tip. This anti-vibration link mechanism C is connected to the stand hanger 12.
A pivot shaft 19 is connected to the connecting boss 18 via a bearing 20.
is provided, and a link 21 is attached to this pivot shaft 19.
The lower ends of are connected.

Further, a connecting plate 22 is fixed to the connecting boss 18. A connecting boss 23 is fixed to the upper end of the link 21. An engaging arm 24 that protrudes upward is fixed to the connecting boss 23, and an engaging body 25 made of an elastic material is provided at the tip of the engaging arm 24. This constitutes an engaging portion B that is inserted into and engaged with A. The connection boss 23 is provided with a seat portion 26, and the connection plate 22 is connected to the seat portion 26 via a buffer mechanism 27.

This buffer mechanism 27 includes elastic members 28 and 29 disposed on the front and back sides of the connecting plate 22, a collar 30,
The restraining plate 31 is fastened to the seat part 26 with a bolt 32 inserted through the collar 30, and the connecting plate 22 is connected to the seat part 2 through the elastic member 28.

At the rear vehicle body 45, the stand 13 is moved against the return spring 14 and touches the ground, and the rear vehicle body 45 is supported by the stand 13 and the rear wheels 43 to bring the rear vehicle body 45 into an upright state.

In this upright state, the engagement arm 24 projects obliquely upward.

In the front vehicle body 41, from a state in which the front wheels 40 are grounded and the vehicle body frame 1 portion is lifted, the vehicle body frame 1 portion is rotated downward about the grounding point O of the front wheels 40 as a fulcrum, and the vehicle body frame 1 portion is rotated downwardly to the lower part of the vehicle body frame 1. The engaging body 25 at the tip of the engaging arm 24, which is the engaging part B of the rear vehicle body 45, is inserted and engaged into the guide recess 7, which is the provided guide part A.

When the engaging body 25 is inserted and engaged in the guide recess 7 in this manner, the connecting hole 11a of the bracket portion 11 of the engine hanger bracket 6 matches the upper connecting boss 23 provided on the link 21.

Therefore, this connecting hole 11a and the connecting boss 2
A pivot shaft 34 serving as a connecting shaft is inserted into the engine hanger bracket 6, and the link 21 of the anti-vibration link mechanism C is connected to the engine hanger bracket 6.

Thereby, the front vehicle body 41 and the rear vehicle body 45 are connected.

Although the body frame 1 of the front body 41 is of a monocot type, it may be of a pipe type.

(Effects of the Invention) As detailed above, the power unit mounting device for a motorcycle according to the present invention can be mounted on a front body including a front wheel and a body frame, and a rear body including a power unit, a rear wheel, and a stand mechanism. an engine hanger bracket provided in the body frame of the front vehicle body and having a connection hole; and a connection boss provided in the rear vehicle body and connected to the connection hole of the engine hanger bracket via a connection shaft. In the motorcycle equipped with a vibration-proof link mechanism, an engaging part having a deformable elastic material is provided on the vibration-proof link mechanism to protrude upward, and the engaging part is inserted into the body frame of the front vehicle body. The invention is characterized in that a guide portion is provided for aligning the connecting boss with the connecting hole of the engine hanger bracket.

Therefore, the rear body is made to stand upright using the stand mechanism and the rear wheels, and the front wheel is grounded on the front body, and the body frame is lifted, and then moved downward using the grounding point of the front wheel as a fulcrum. When the engaging part on the rear vehicle body side is inserted and engaged with the guide part, the connecting boss of the connecting part can be aligned with the connecting hole of the engine hanger bracket.
