Abstract

An oil strainer 51 includes: a lower member 52 having an oil suction hole 52f opening in oil stored in an oil pan; an upper member 53 having an oil discharge hole 53a leading to an oil pump; and a strainer element 55. The lower member 52 and the upper member 53 are joined to each other with the strainer element 55 held between joint surfaces of the upper and lower members 52 and 53. Thus, it is possible to form the oil strainer 51 into a flat shape so as to be compactly arranged in a narrow space, and also maximize an area of the strainer element 55 to prevent clogging. Further, the lower member 52 and the upper member 53, which are die-molded articles, are highly flexible in their shapes, whereby the oil suction hole 52f and the oil discharge hole 53a can be arranged in the most suitable positions, and the cross-sectional area of oil flow can be sufficiently secured.

Claims (8)

1. An oil strainer structure of an engine, comprising:

an oil strainer for filtering oil in an oil pan, the oil strainer being arranged between a balancer housing and the oil pan of the engine and supported by the balancer housing, the oil strainer including:

a lower member which is a die-molded article having an oil suction hole opening in the oil stored in the oil pan, an upper member which is a die-molded article having an oil discharge hole leading to the oil pump, and a strainer element, the lower member and the upper member being joined to each other with an outer peripheral portion of the strainer element held between joint surfaces of the upper and lower members.
2. The oil strainer structure of an engine according to claim 1, wherein the oil strainer has a cross-sectional area decreasing from the oil suction hole to the oil discharge hole.
3. An oil strainer structure of an engine, comprising:

an oil strainer for filtering oil in an oil pan, the oil strainer including two members joined to each other and being supported on a lower surface of a balancer housing of the engine, wherein an oil return member for returning oil separated from blowby gas is formed by two members joined to each other, and wherein one of the two members forming the oil return member is commonly used as one of the two members forming the oil strainer.
4. The oil strainer structure of an engine according to claim 3, wherein the commonly used member is a lower member; and the lower member and a first upper member that is joined to the balancer housing constitute the oil strainer, and the lower member and a second upper member that is joined to the balancer housing constitute the oil return member.
5. An oil strainer structure of an engine, comprising:

an oil strainer for filtering oil in an oil pan, the oil strainer being supported on a lower surface of a balancer housing of the engine, wherein the oil strainer is supported so as to provide a bridge between opposite ends of the balancer housing.
6. The oil strainer structure of an engine according to claim 5, further comprising a rib which is projectingly provided on an upper or lower surface of the oil strainer.
7. The oil strainer structure of an engine according to claim 5 or 6, further comprising an oil return member for returning oil separated from blowby gas to the oil pan, the oil return member being integrally formed at a joint portion where an end of the oil strainer is joined to the balancer housing.
8. An oil return structure of an engine, comprising:

an oil return member for returning oil separated from blowby gas to an oil pan, the oil return member being arranged between a balancer housing and the oil pan of the engine, the oil return member including:

an upper member which is a die-molded article having an oil inlet hole leading to an oil return passage in the balancer housing; and a lower member which is a die-molded article having an oil outlet hole opening in the oil in the oil pan, the upper and lower members being joined to each other.
