Patent

CA 2689648

In an engine air cleaner, a suction opening (50) communicating with outside air and a discharge opening (16) communicating with an engine (E) are provided in an upper cover body (11) of a cleaner cover (10), a cleaner element unit (Ue) for cleaning the outside air sucked in via the suction opening (50) is housed within the upper cover body (11), and a skirt wall (11a) of the upper cover body (11) in the vicinity of the suction opening (50) extends further downward than the suction opening (50). This prevents raindrops running down the outer face of the cleaner cover body (11) from being sucked into the interior of the air cleaner via the suction opening (50). Further, a seal packing (68) and the cleaner element unit (Ue) are superimposed and fitted onto an outer periphery of an intake passage (17) within the cleaner cover body (10), the seal packing (68) preventing outside air from leaking directly into the discharge opening (16), and the seal packing (68) is provided with a retaining projection (75) that is tightly engaged with the intake passage (17). This prevents the seal packing (68) from being unintentionally detached from the cleaner cover body (10) when replacing the cleaner element unit (Ue), etc., thus preventing assembly of the seal packing (68) from being forgotten or the seal packing (68) from being lost. Furthermore, an air cleaner (AC) is disposed so as to be side by side with one side of the engine (E), a lower part of the cleaner cover body (10) is joined integrally to and supported on the engine (E) together with a carburetor (4) via a pair of connecting bolts (22, 23), and a reinforcing vertical wall portion (37) of the cleaner cover body (10) facing the engine (E) across a gap is joined integrally to and supported on the engine (E) via another connecting bolt (24). This enhances the rigidity with which the air cleaner is supported on the engine (E).
