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).
L~invention se rapporte à un épurateur d~air (EA) d~un moteur, dans lequel une paroi de jupe (11a) d~un corps de couvercle supérieur (11) à proximité d~un orifice d~aspiration (50) est étendue jusqu~au côté inférieur de l~orifice d~aspiration (50), pour empêcher les gouttes de pluie coulant sur la surface externe d~un corps de couvercle d~épurateur 10) d~être aspirées dans l~épurateur d~air à travers l~orifice d~aspiration (50). Un joint de garniture (68) et une unité d~élément d~épurateur (Ue) sont intégrés par empilement à la périphérie externe d~une voie d~aspiration (17) dans le corps du couvercle (10) de l~épurateur et une protubérance de verrouillage (75) fermement en prise avec la voie d~aspiration (17) est formée sur le joint de garniture (68) pour empêcher le joint de garniture (68) de tomber lorsqu~on remplace l~unité d~élément d~épurateur (Ue). En outre, l~épurateur d~air (EA) est disposé sur un côté du moteur (E) parallèlement à celui-ci, la partie inférieure du corps de couvercle (10) de l~épurateur est intégralement reliée au moteur (E) et repose sur celui-ci, avec un carburateur (4), à l~aide d~une paire de goujons de connexion (22, 23). La partie de paroi verticale de renforcement (37) du corps de couvercle (10) d~épurateur faisant face au moteur (E) via un espace est intégralement reliée au moteur (E) et repose sur celui-ci, à l~aide de l~autre goujon de connexion (24). Ainsi, la rigidité du support de l~épurateur d~air pour supporter l~épurateur d~air sur le moteur (E) peut être renforcée.
