Oil strainer structure of engine and oil return structure of engine |
(57) 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.
