けとほぼ同様にして取付ければＪ−い。In the usage example of the oil cooler (1) described above, the length direction of the heat dissipation fins (4) is in a slightly inclined and almost parallel state with respect to the traveling direction of the two-wheeled vehicle. may be parallel to the direction of travel. In addition, in the above usage example, J3 has a hole (22) in the cowling (21).
The oil cooler (1) is attached to the cowling (21) so that the heat dissipation fins (4) come out of the cowling (21) through the holes (22), but the present invention is not limited to this. Only a hole is formed in the cowling (21) through which the pipe connecting member (6) passes, and the oil cooler (1) is inserted into the cowling (21) so that the pipe connecting member (6) enters the cowling (21) through this hole. 21) It may be placed along the outer surface and attached to the cowling (21). Roughly speaking, the above usage example is for a two-wheeled vehicle, but in the case of a four-wheeled vehicle, it can be attached to the side of the body in almost the same way as it is attached to the nozzle ring of a two-wheeled vehicle.

なる。Effects of the Invention The oil cooler according to the present invention has an oil cooler body made of a flat hollow extruded aluminum material with an oil passage inside the oil cooler body, and an oil cooler body made of a flat hollow extruded aluminum material, which is provided on the side of the oil cooler body, and has an oil passage inside the oil cooler body. The bulk of the oil cooler is lower than that of conventional oil coolers.
Since the installation space is small, it does not interfere with other equipment,
Alternatively, it can be installed in a location where a sufficient cooling effect can be obtained without being disturbed. In the case of a two-wheeled vehicle, the direction of the air guided by the radiation fins is
It is possible to install it on the side of the U-ring so that it is parallel or almost parallel to the direction of travel, allowing air to efficiently hit the heat radiation fins while driving, improving oil cooling efficiency and reducing bulk. Because it is low, the resistance while running is also small. In addition, in the case of four-wheeled vehicles, it is possible to install them on the side of the body so that the direction of the air guided by the heat dissipation fins is parallel or almost parallel to the direction of travel, which allows the air to flow more efficiently while driving. It hits the heat dissipation fins well, resulting in excellent oil cooling efficiency and low stiffness, which reduces resistance while driving. Furthermore, the installation work is easier than when installing in the engine room.
