    • 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.
    • 滤油器51包括:下部件52,该下部件52具有开口于存储在油盘中的油中的吸油孔52f; 具有通向油泵的排油孔53a的上部件53; 以及过滤器元件55.下部件52和上部件53通过过滤器元件55保持在上部件52和下部件53的接合表面之间而彼此接合。因此,可以形成滤油器51 成扁平形状以致紧凑地布置在狭窄的空间中,并且还使过滤器元件55的面积最大化以防止堵塞。 另外,由于作为模塑成形品的下部件52和上部件53的形状柔软性高,因此能够将吸油孔52f和排油孔53a配置在最合适的位置, 可以充分确保油流的截面积。
