PROBLEM TO BE SOLVED: To provide a lubricating device for an engine that can reduce passage resistance of an oil strainer and can eliminate the necessity of a support stay of an oil filter.SOLUTION: An oil strainer 2 includes an outer cylinder 5 and an inner cylinder 6. The outer cylinder 5 and the inner cylinder 6 have straight center axes 5a, 6a, respectively, and serve as an inner and outer double cylinder. A strainer inlet 4 is provided at a lower end of the outer cylinder 5, and a peripheral wall of the inner cylinder 6 serves as a filter portion 6b. The oil strainer 2 is downwardly obliquely led out from a cylinder block 1 toward an inner bottom portion of an oil pan 3. An upper end 5b of the outer cylinder 5 is fixed to the cylinder block 1, and an upper end opening 6c of the inner cylinder 6 is communicated with an oil passage inlet 1a of the cylinder block 1.SELECTED DRAWING: Figure 1 |
