Abstract: A vehicular muffler mounting structure in which a muffler is supported inside wheels by a body frame is provided. The muffler is connected to the body frame through a fastener that is screwed substantially parallel to the lengthwise direction of a body.

Abstract: A vehicular air intake system including a resonator for eliminate the possibility of dust and water droplets collecting in the resonator. An end portion of an air intake duct is branched into a resonator and an air intake section. In the air intake section, a chamber is formed having an air intake port for taking in outside air. The resonator is disposed upwardly of the air intake port. A branch pipe section and the chamber are positioned such that they are slightly inclined downwardly toward a main pipe section. In this arrangement, the air intake duct is disposed downwardly of a seat and a resin cover such that the air intake port is located a required distance away from a rear external surface of a fuel tank.

Abstract: To improve throttle response and productivity of an air cleaner of a vehicle. A vehicular air cleaner structure is provided, in which an air cleaner is mounted to a vehicle body frame and an intake duct for drawing air in the air cleaner and a connecting tube for providing communication between the air cleaner and the side of an engine are connected to the air cleaner. The intake duct and the connecting tube are connected to the air cleaner. A connection rubber capable of being flexed by a change in pressure in the air cleaner is disposed on a side wall as at least one of walls of the air cleaner.

Abstract: An air cleaner is provided in an all terrain vehicle in order to improve the control performance for effecting optimal combustion in an engine by accurately measuring the temperature of air introduced into the engine. The air cleaner includes an air cleaner case disposed behind an engine, a throttle valve disposed between the engine and the air cleaner case, and connecting tube for connecting the air cleaner case and the throttle valve with each other. A temperature sensor is disposed in either a front or rear face of the air cleaner case. Optionally, the temperature sensor is disposed in the connecting tube.

Abstract: A vehicular radiator unit has an improved support stay for a cooling fan, making it possible to reduce the amount of time necessary to mount the cooling fan to a heat radiating part. The vehicular radiator unit includes a radiator supported by a body frame. A cooling fan enhances the heat radiating performance of the radiator. A support stay supports the cooling fan and is attached to the radiator. The support stay includes plural arms. The lower arm holds the radiator by sandwiching a peripheral portion thereof.
