A mounting structure for an oil pan (10) is disclosed. The oil pan (10) includes an outer pan (11) made from a metal and an inner pan (20) made from a synthetic resin and fixed to an underside of an engine (50) by bolts (B). The mounting structure includes abutments (12T, 52T) formed on outer portions of the opening edges (12, 52) of the outer pan (11) and the engine (50) so as to abut against each other, respectively, bolt holes (12B, 52B, 52C, 12C) formed through the outer peripheral portions of the opening edges (12, 52) so that the bolts (B) are inserted through the bolt holes (12B, 52B, 52C, 12C) respectively, an accommodation space (56) defined between inner peripheral portions of the opening edges (12, 52) of the outer pan (11) and the engine (50) by collapsing the inner peripheral portion of the opening edge of either outer pan (11) or engine (50), and a flange (25) protruding sideways from the inner pan (20) and loosely fitted in the accommodation space(56).
