1. A double sump oil pan comprising: a separator made of plastic that partitions an interior of the oil pan into an inner sump and an outer sump, and the separator has a protrusion;a plate that has an insertion hole, which receives the protrusion; andan elastically deformable sealing member attached to the plate, whereinthe sealing member contacts an inner wall of the oil pan, thereby sealing the outer sump, andthe plate and the separator are fixed to each other by heat-swaging the protrusion. 2. The double sump oil pan according to claim 1, wherein the sealing member is a rubber lip. 3. The double sump oil pan according to claim 1, wherein the plate has a ring-like shape, andthe sealing member is attached to an entire perimeter of the plate. 4. A double sump oil pan comprising: a separator that partitions an interior of the oil pan into an inner sump and an outer sump;a plate; andan elastically deformable seal attached to the plate, whereinthe seal contacts an inner wall of the oil pan along which oil flows down, and the seal guides the oil directly on a face of the seal to go down the face of the seal and away from the inner wall, thereby sealing the outer sump, the face of the seal includes at least a portion that declines, with respect to a vertical direction relative to the ground, toward the inner sump, andthe plate and the separator are fixed to each other. 5. The double sump oil pan according to claim 4, wherein the separator has a protrusion,the plate has an insertion hole, which receives the protrusion, andthe plate and the separator are fixed to each other by heat-swaging the protrusion. 6. The double sump oil pan according to claim 4, wherein the seal is a rubber lip. 7. The double sump oil pan according to claim 4, wherein the plate has a ring-like shape, andthe seal is attached to an entire perimeter of the plate. 8. The double sump oil pan according to claim 4, wherein the separator is made of plastic. 9. The double sump oil pan according to claim 4, wherein the seal seals a gap between the separator and the inner wall of the oil pan. 10. The double sump oil pan according to claim 4, wherein one or more side wall of the separator includes at least one through hole to permit a communication of the oil between the inner and outer sumps, and a bottom wall of the separator does not include any through hole. 11. The double sump oil pan according to claim 4, wherein the plate includes an inward portion that declines, with respect to the vertical direction relative to the ground, toward the inner sump. 12. A double sump oil pan comprising: a separator that partitions an interior of the oil pan into an inner sump and an outer sump; a plate; and an elastically deformable seal attached to the plate, wherein the seal contacts an inner wall of the oil pan along which oil flows down, and the seal guides the oil directly on a face of the seal to go down the face of the seal and away from the inner wall, thereby sealing the outer sump, the face of the seal includes at least a portion that extends in a vertical direction relative to the ground, and the plate and the separator are fixed to each other.
