ABSTRACT:
The present invention provides an oil pan with a built-in filtering element which does not easily receive influence of lateral swing of oil, which has high support rigidity of a filter, or which has excellent assembling operability of the filter, or which is light in weight as compared with a conventional oil pan. The oil pan P1with a built-in filtering element has a filter20. The filter20is provided therein with an oil flow path Q which is in communication with an oil pump. The filter20filters oil flowing toward the oil pump. An oil flow path includes a bottom flow path Qb having a flow path wall7extending along a bottom wall5of the oil pan, and a side flow path Qs having a flow path wall8extending along a first sidewall1of the oil pan. The first sidewall includes a drain hole1hwhich opens at the bottom flow path and through which the filter can be inserted into the bottom flow path. The bottom flow path is provided with a filter retaining portion7kwhich retains the inserted filter. The drain hole is provided with a plug fixing portion1mwhich fixes a closing plug10of the drain hole. The closing plug is formed with a filter receiver11kagainst which a terminal end20kof the inserted filter is abutted.
