  The strainer 3 is provided in the oil stored in the oil pan 7. The pipe member 6 includes a horizontal portion 61 that extends in the horizontal direction from one end connected to the oil pump 5, and a vertical portion 62 that extends substantially downward in the vertical direction from the opposite side of the horizontal portion 61 to the oil pump 5. The other end side of the pipe member 6, that is, the lower end of the vertical portion 62 is connected to the strainer 3.

  One end portion 8a of the bracket 8 is fastened and fixed to the cylinder block 4 via a bolt, and is fixed to the vertical portion 62 of the pipe member 6 by welding at the other end portion 8b. The one end 8a of the bracket 8 may be fixed to the cylinder block 4 via a stay. Moreover, the one end 8a of the bracket 8 may be fixed to the cylinder block 4 by a method such as welding.

  Next, with reference to FIG. 2, the fixing | fixed part of the other end part 8b of the bracket 8 and the vertical part 62 of the pipe member 6 is demonstrated. FIG. 2A is an enlarged view of the fixed portion viewed from the right side of FIG. FIG. 2B is an enlarged view of FIG. FIG.2 (c) is AA sectional drawing in Fig.2 (a). FIG.2 (d) is BB sectional drawing in FIG.2 (b). In addition, the bracket 8 is abbreviate | omitted in FIG.2 (c) and FIG.2 (d).

  The other end 8 b of the bracket 8 is curved along the outer shape of the pipe member 6. The other end portion 8 b of the bracket 8 is provided with a pair of inclined portions 81, a pair of continuous portions 82 (first extending portions), and a concave portion 83. The pair of inclined portions 81 are provided so as to approach each other toward the tip of the bracket 8.

  The recess 83 is provided at the center in the width direction of the bracket 8. The recess 83 includes a pair of parallel portions 84 and a bottom portion 85 that connects the back side ends of the pair of parallel portions 84. The pair of continuous portions 82 respectively connect the other end (lower end) of the inclined portion 81 and the other end (lower end) of the parallel portion 84.

  When the bracket 8 is fixed to the pipe member 6, the pair of continuous portions 82 are disposed so as to extend in a direction substantially orthogonal to the length direction of the pipe member 6, and the first welded portion 92 is attached to the pipe member 6. It is fixed by welding. When the bracket 8 is fixed to the pipe member 6, the pair of inclined portions 81 are also welded and fixed to the pipe member 6 via the second welding portion 91. Further, when the bracket 8 is fixed to the pipe member 6, the pair of parallel portions 84 and the bottom portion 85 in the concave portion 83 are also welded and fixed to the pipe member 6 via the third welding portion 93.

  That is, the bracket 8 is welded and fixed to the pipe member 6 with a pair of continuous portions 82, a pair of inclined portions 81, and a concave portion 83 extending in a direction substantially orthogonal to the length direction of the pipe member 6. It is fixed to the pipe member 6 through the one welded portion 92, the second welded portion 91 and the third welded portion 93.

  Here, with reference to FIG. 3, as a reference example, it is assumed that the pair of inclined portions 81 and the concave portions 83 are not provided, and only the distal end sides of both end portions are welded and fixed to the pipe member 6. FIGS. 3A and 3B are diagrams corresponding to FIGS. 2A and 2B in the reference example.

  As the engine 1 vibrates, stress in the left-right direction in FIG. 3B is applied to the fixed portion between the pipe member 6 and the bracket 8. At this time, in the reference example, since the extending direction of the welded portion 19 is substantially orthogonal to the stress load direction, the welded portion 19 is easily damaged. If the welded portion 19 is damaged, the pipe member 6 cannot be supported by the bracket 8. Furthermore, there is a possibility that the pipe member 6 has a hole, which hinders oil suction.
