Description of the invention (9) The outer cylinder 5 8 is rotated by the elastic deformation of the rubber bush 5 6. A mechanism that more elastically suppresses the rotation of the outer cylinders 5 7, 5 8 · is provided between the cross tube 8 and the front outer cylinder 5 7. That is, in the center of the cross tube 8, the opening of the rectangular box body 70 is inclined obliquely toward the outer tube 57, and it is embedded with rubber 71 inside. One of the outer tubes 5 7 is projected obliquely above the center of the outer tube 57. The protrusion 72 is inserted into the rubber 71 of the case 70. As described above, a load in the front-rear direction is applied to the bracket 16 and the protrusion 7 2 elastically deforms the rubber 71 to prevent the outer tube 57 from rotating around the support shaft 53 as the center. The internal combustion engine 25 is supported by the support shaft 50 and the support shaft 61 in such brackets 16, 16, and the front end of the rear frame fork 18 is supported by a pivot shaft 17. Therefore, the vibration of the internal combustion engine 25 can be reduced to be transmitted to the vehicle body frame 2 side by the presence of the rubber bushes 55, 56, 61 '66 and the rubber 71 provided at the four-point connecting link 15. Further, referring to FIG. 1, a straight line L connecting the ground point of the rear wheel 19 and the pivot 17 of the rear frame fork 18 is formed between the front and rear support shafts 50'6 7 of the bracket 16. Therefore, for the movement of the rear wheels 19, it is possible to suppress the movement of the bracket 16 through the rear frame forks 18, and to suppress the posture change of the internal combustion engine. When accelerating, the rotation of the rear wheel 19 causes the rear frame fork 18 to push forward toward the vehicle body, and it acts on the pivot 16 of the bracket 16 on the rear frame fork 18 to the front. Force, as shown by the solid line in Figure 5 (Figure 5 is for the purpose of saying ----_--------- making -------- ordering -------- I ^ -1 ^^} 1 (Please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) -12- A7 436442 B7___ V. Description of the invention (1 〇) For the sake of clarity, the action is exaggerated.) According to the elastic deformation of the rubber bushings 6, 1, 6, the outer ring members 6 0, 65 are shaken and deformed forward. Previously, the deformation of the outer ring member 60 was transmitted through the connecting member 5. 9. With the support shaft 5 3 as the center, the outer sleeve 57 is rotated clockwise in the left side view by the elastic deformation of the rubber bush 5 5, and the deformation of the rear outer ring member 65 is transmitted through the connecting member 6 4 With the support shaft 5 4 as the center and the elastic deformation of the rubber bush 5 6, the outer cylinder 5 8 is rotated clockwise in the left side view. In addition, the rotation of the front outer cylinder 5 7 causes the integral protrusion 7 2 to swing clockwise in the left side view so as to elastically deform the rubber 71 in the vehicle body side box 70. Therefore, the force acting on the vehicle body during acceleration is cushioned by the rubber 71 and the rubber bushes 55, 56 '61' 6 6 provided at the four-point connecting link 15. When decelerating, for the vehicle body frame 2, a backward force acts on the bracket 16 as shown by the dotted line at 2 of FIG. 5 so that the front and rear outer cylinders 5 7 '5 8 are counterclockwise on the left side view. Directional rotation 'With rubber 7 1 and rubber bushings 5 5' 5 6 '6 1, 6 6 which are connected to the connecting rod 15 at 4 points, the force acting during deceleration is cushioned to suppress the impact on the vehicle body. Here, the four-point connecting link 15 has a rear connecting member 64 that is longer than the front connecting member 59. The swing angle of the front outer ring member 60 is greater than the swing angle of the rear outer ring member 65. It is also large that 'the deformation amount of the bracket 16 and the internal combustion engine 25 is restricted by the short connecting members 59, and the necessary movement is prevented. In addition, the rotation angle of the front outer cylinder 5 7 is greater than the rotation of the rear outer cylinder 5 8 (please read the precautions on the back before filling this page) ---- Order -------: Line ^-Ministry of Economy The paper size printed by the Intellectual Property Bureau employee consumer cooperative is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -13-A7 436442 _______B7_____ V.
