Abstract (en)

[origin: EP2163738A1] In a breather device for an engine, since a predetermined gap (±) is formed between an outer surface of a breather chamber (26) disposed in the interior of a head cover (13) and an inner surface of the head cover (13), even if the outside temperature decreases, the gap (±) functions as an insulating space, thereby preventing blow-by gas from freezing in the interior of the breather chamber (26). Moreover, since a blow-by gas inlet (30) formed in a wall face of the breather chamber (26) is made to open at a position that faces the inner surface of the head cover (13), compared with a case in which the blow-by gas inlet (30) is made to open in a lower face of the breather chamber (26), not only can the degree of freedom for the position of the blow-by gas inlet (30) be increased, but it is also possible for an effect in separating oil to be exhibited by means of the gap (±) between the breather chamber (26) and the head cover (13), thereby preventing oil from entering the breather chamber (26).
