2. Description of the Related Art In a conventional engine intake system including a resonator, a resonator is arranged in the vicinity of the air cleaner and is usually attached to the vehicle body separately. And, in the middle of the intake hose connecting the throttle body and the air cleaner, the connection hose is branched and connected to the resonator to suppress intake noise,
The electronically controlled fuel injection and supply system is designed to improve the torque characteristics at low speeds (for example, in Japanese Utility Model Laid-Open No. 51-1.
56308).

As for the carburetor type intake device provided with a cooling / heating switching valve, there is known an air cleaner integrally provided with the cooling / heating switching valve.

However, although the air cleaner and the resonator are arranged close to each other, they are separately configured and separately mounted on the vehicle body, so that the number of parts is increased and the cost is increased. At the same time, there is a problem that the installation space also becomes large because it is necessary to secure a mounting space for each.

Further, even though an air cleaner integrated with a cooling / heating switching valve is known, it is constructed separately from an ordinary air cleaner and is not configured to be commonly used, so that there is a problem that the cost is increased.

In view of the above problems of the prior art, the present invention provides an air cleaner structure which is integrated with a resonator and an air cleaner structure which can be used for both an air cleaner integrated with a resonator and an air cleaner integrated with a cooling / heating switching valve. The purpose is to
