Abstract

An oil strainer support structure for an internal combustion engine capable of improving the maintainability of an oil strainer is provided. In an oil strainer support structure for an internal combustion engine having an oil strainer, the oil strainer is supported by a drain bolt provided in the internal combustion engine. The oil strainer can be detached by removing the drain bolt to improve maintainability.

First claim

The invention claimed is:

1. An oil strainer support structure for an internal combustion engine having an oil strainer,
wherein an oil inlet of the oil strainer is provided with an annular flange and the flange is fitted with a filter that reduces suction of a foreign matter,
a drain bolt is provided with a hollow portion that is open at a leading end of the drain bolt, said hollow portion being provided with a plurality of pressing portions that project from an edge of the hollow portion, wherein
each of the pressing portions define an opening,
the filter is inserted in the hollow portion of the drain bolt,
the pressing portions of the drain bolt abut against the annular flange, and
the oil strainer is supported by the drain bolt that is provided in the internal combustion engine.

2. The oil strainer support structure according to claim 1 ,
wherein an outer diameter of the oil strainer is smaller than an inner diameter of an internal thread of a threaded hole to which the drain bolt is screwed.

3. The oil strainer support structure according to claim 2 ,
wherein the internal combustion engine is provided with a baffle that prevents undulation of an oil surface of oil, the baffle is provided with a baffle opening, and the oil strainer passes through the baffle opening.

4. The oil strainer support structure according to claim 1 ,
wherein the internal combustion engine is provided with a baffle that prevents undulation of an oil surface of oil, the baffle is provided with a baffle opening, and the oil strainer passes through the baffle opening.

5. The oil strainer support structure according to claim 1 , further comprising a crankcase having an oil inflow port and an oil passage,
wherein the oil inflow port is formed in the crankcase in order to connect one end portion of the oil strainer to the oil passage of the crankcase, and an inner diameter of a partition wall opening is larger than a maximum inner diameter of the inflow port.

6. The oil strainer support structure according to claim 1
wherein a bottom of the crankcase has a pair of convex portions, and the oil inlet of the oil strainer is provided between the pair of convex portions.
