Effects of the invention As is clear from the above explanation, at least one locking protrusion protruding from the top and bottom of the air cleaner assembly is connected to the engagement hole of the elastic member fitted into the support hole of the vehicle body side member. The upper and lower elastic members are fitted vertically into the support hole, and are pressed and fixed with a fixing member so that at least one of the upper and lower elastic members does not separate from the support hole, and the at least one of the upper and lower elastic members is A locking protrusion that is loosely fitted in advance into the support hole is fitted into the support hole, and is pressed and fixed by a fixing member that is directed from the mounting direction of at least one of the upper and lower elastic members. A structure for attaching an air cleaner assembly to a vehicle body has been proposed.

The effects obtained by this structure are as follows.

The air cleaner assembly is supported by fitting the upper and lower locking protrusions into the support holes of the vehicle body side member via the elastic member, so there is no direct need for fixing bolts, and the parts The number of parts is small and assembly is easy.

Since the upper and lower locking protrusions are engaged with the support holes of the vehicle body side member through the elastic members, vibrations of the vehicle body are difficult to be transmitted to the air cleaner assembly.

The locking protrusions protruding from the top and bottom surfaces of the air cleaner assembly are oriented vertically and fit into the engagement holes of the elastic members. When the air cleaner assembly moves up and down, the load that acts on the upper and lower elastic members only acts as a compressive force on the elastic members that are supported from behind by the vehicle body side members or fixed members. Since the load on the members is small, durability is good, and the air cleaner assembly is always stably supported.

When assembling the air cleaner assembly to the vehicle body, there is no fear of applying excessive prying force to the elastic member due to the locking protrusion, and the assembling is simple and the assembling workability is good.
