Abstract: To provide a cooling apparatus for a vehicle enabling protection of a cooling device by effectively utilizing a vehicle frame. The cooling apparatus, which is attached to a vehicle including a vehicle frame and a steering member provided at a front upper portion of the vehicle frame, has a heat exchanger, which performs thermal exchange with the outside air. The heat exchanger is provided within an area formed with a vertical plane passing through a front end of the vehicle frame and a horizontal plane passing through an upper end of the steering member.

Abstract: A vehicular air cleaner having an air inlet and an air outlet formed in one side of an air cleaner case. An air intake duct is connected to the air inlet through a duct seal, and a connecting tube connected to a carburetor is connected directly to the air outlet. The air cleaner device is provided with a combined seal-tube having an integral duct seal and connecting tube.

Abstract: To improve the low-temperature resistance of a blow-by gas treatment device. An air cleaner is connected through a carburetor to the intake side of a cylinder portion constituting an engine in a four-wheel buggy. A blow-by gas induction pipe is provided to connect a crankcase and one side surface of the air cleaner, so as to induce a blow-by gas from the crankcase to a return chamber defined in the air cleaner at one side portion thereof. An exhaust pipe extends rearwardly from the exhaust side of the cylinder portion along a part of the induction pipe, and is connected to a muffler. The muffler is located in the vicinity of the return chamber in the air cleaner, so as to warm the return chamber by the heat radiated from the muffler, thereby ensuring good returnability of the blow-by gas even at low temperatures. The exhaust pipe similarly warms the induction pipe.
