  Referring also to FIG. 5, the two first fastening members 71 are each fastened to the engine-side stay 64 via the first rubber 101, and the second fastening member 72 is fastened via the second rubber 102. It is concluded. That is, since the first fastening member 71 and the second fastening member 72 are rubber-mounted, vibration generated in the engine 14 and the vehicle body frame 11 is not easily transmitted to the heat exchanger 60. As a result, vibration of the heat exchanger 60 is suppressed.

  In the present embodiment, the rubber member is interposed in the second fastening member. However, the rubber member may be interposed in the third fastening member. Alternatively, a rubber member may be interposed in the third fastening member, and a rubber member may not be interposed in the second fastening member.

Next, the operation of the front structure of the saddle-ride type vehicle described above will be described.
3 and 5 together, the upper heat exchanger (radiator 61) and the lower heat exchanger (oil cooler 62) are connected by connecting members 75L and 75R, and the upper heat exchanger (radiator 61). The lower end 60b and the upper end 60a of the heat exchanger 60 including the lower heat exchanger (oil cooler 62) are supported by the vehicle body frame 11 or a vehicle body component such as the engine 14 provided on the vehicle body frame 11. The

  Conventionally, in order to support the upper heat exchanger and the lower heat exchanger, for example, it is necessary to attach the upper and lower parts of the upper heat exchanger to the vehicle body frame and the engine and to attach the upper and lower parts of the lower heat exchanger to the vehicle body frame and the engine. is there. Then, there is a possibility that the number of parts such as mounting stays will increase.

  In this regard, in the present invention, the upper heat exchanger (radiator 61) and the lower heat exchanger (oil cooler 62) are connected by connecting members 75L and 75R, and the upper end 61a of the upper heat exchanger (radiator 61) is connected. Attached to the main frames 13L and 13R, the lower end 62b of the lower heat exchanger (oil cooler 62) was attached to the engine 14. Accordingly, an increase in the number of parts related to mounting can be suppressed, and the upper heat exchanger (radiator 61) and the lower heat exchanger (oil cooler 62) can be reliably supported on the vehicle body side.

  Referring also to FIG. 2, a pair of left and right upper end support portions 93 </ b> L and 93 </ b> R extending upward to the upper end 61 a of the upper heat exchanger (radiator 61) are fastened from the outer side in the vehicle width direction toward the inner side. The lower end support portion 94 that is fastened at the bottom and extends rearward to the lower end 62b (see FIG. 3) of the lower heat exchanger (oil cooler 62) is fastened from the bottom to the top, that is, from the outside to the inside. Fastened at 73.

  Thus, since the upper end 61a of the connected upper heat exchanger (radiator 61) and the lower end 62b of the lower heat exchanger (oil cooler 62) are both fastened from the outside to the inside, the assemblability is improved. Can be increased. In addition, since the fastening directions coincide with each other, it is possible to easily absorb the dimensional variation of the parts by moving the integrated heat exchanger 60 back and forth and up and down.

  Further, the first fastening member 71 is fastened via the first rubber 101, and the second fastening member 72 is fastened via the second rubber 102. This makes it difficult for vibration generated in the engine 14 and the vehicle body frame 11 to be transmitted to the heat exchanger. As a result, vibration of the heat exchanger 60 is suppressed.

  The front exhaust pipe 51 extending from the front bank 43 of the engine 14 has a front protrusion 52, and the pipe extending from the radiator 61 has an upper pipe 88 extending along the upper end 61 a of the radiator 61. An upper pipe 88 is disposed above.

  The space between the front bank 43 and the front exhaust pipe 51 of the engine 14 is a limited space. Since the upper pipe 88 is disposed above the front projecting portion 52 of the front exhaust pipe 51 which is such a limited space, the expansion of the occupied space around the radiator 61 can be suppressed. As a result, the layout around the radiator 61 can be made compact.

Next, a case where the radiator is changed to a specification different from that of the embodiment will be described. In the figure, the oil cooler is omitted.
As shown in FIG. 6, the radiator 61 </ b> B has a tube and fins, and a water core portion 81 </ b> B that exhibits a heat dissipation action when the traveling wind passes through, and left and right radiators provided at the left and right ends of the water core portion 81 </ b> B Tanks 82BL and 82BR. An electric fan is not attached.

  An input port 85 through which a cooling medium is input is provided on the upper side of the right radiator tank 82BR. An upper pipe 88B extends to the input port 85 along the upper end 61Ba of the radiator 61B. The pipe extending from the radiator 61B has an upper pipe 88B extending along the upper end 61Ba of the radiator 61B. A major difference from the embodiment is that the upper pipe 88B has a long metal portion.

  If the upper pipe 88B is made of a long metal part, the heat of the cooling refrigerant can easily escape to the outside as compared with the case where a part of the upper pipe is made of rubber or resin. As a result, the cooling performance of the radiator 61B can be improved. Other structures and operations are the same as in the embodiment, and a description thereof is omitted.

Although the present invention is applied to a motorcycle in the embodiment, it can also be applied to a tricycle and can be applied to a general vehicle.
Also, the upper heat exchanger may be an oil cooler and the lower heat exchanger may be a radiator. Alternatively, both the upper heat exchanger and the lower heat exchanger may be radiators, or both the upper heat exchanger and the lower heat exchanger may be oil coolers.

  The present invention is suitable for a motorcycle having a heat exchanger at the front of the vehicle.
