Abstract
Official abstract text for this publication.
A sealing-equipped oil pan includes a gasket and an oil pan having a bottom portion and a peripheral wall for storing oil, and a ring-shaped rim portion located at an end of the peripheral wall and provided with the gasket, and is fastened to a target device with the gasket interposed between the rim portion and the target device. The gasket has a projection projecting from a sealing surface configured to come into contact with the target device for sealing. The peripheral wall of the oil pan has a base portion projecting from the rim portion and supporting the projection of the gasket. The base portion supports the projection of the gasket to prevent the gasket from tilting with respect to the rim portion, thereby preventing protrusion of the gasket.

The invention claimed is: 1. A sealing-equipped oil pan comprising: a sealing member that is composed of an elastic member; and an oil pan that has a bottom portion, a peripheral wall, and a rim portion, the bottom portion and the peripheral wall being configured to store oil, the rim portion having a ring shape, located at an end of the peripheral wall, and provided with the sealing member, the sealing-equipped oil pan being configured to be fastened to a target device with the sealing member being interposed between the rim portion and the target device, wherein the sealing member has a projection projecting from a sealing surface configured to come into contact with the target device for sealing, and the peripheral wall of the oil pan has a base portion projecting from the rim portion and supporting the projection of the sealing member, wherein the base portion projects in a direction intersecting a fastening direction of the oil pan and expands from the rim portion toward a region where oil is stored with respect to the rim portion having the ring shape, wherein the base portion has a flat portion supporting the projection of the sealing member, and the flat portion has a trapezoidal shape whose longer bottom side faces the rim portion. 2. The sealing-equipped oil pan according to claim 1 , wherein the projection of the sealing member projects in the direction intersecting the fastening direction of the oil pan in such a manner that a height of the projection of the sealing member inside the rim portion having the ring shape is larger than a height of the projection of the sealing member outside the rim portion having the ring shape. 3. The sealing-equipped oil pan according to claim 2 , wherein the sealing member has a return portion located at a distal end of a side wall extending along a shape of the rim portion and projecting toward inside of the rim portion. 4. The sealing-equipped oil pan according to claim 3 , wherein the oil pan has a plurality of washer portions projecting outward from the rim portion and each having a bolt hole through which a bolt to be screwed to the target device so as to fasten the oil pan to the target device is inserted, and the base portion is provided on a straight portion of the rim portion located between two of the washer portions. 5. The sealing-equipped oil pan according to claim 1 , wherein the sealing member has a return portion located at a distal end of a side wall extending along a shape of the rim portion and projecting toward inside of the rim portion. 6. The sealing-equipped oil pan according to claim 1 , wherein the oil pan has a plurality of washer portions projecting outward from the rim portion and each having a bolt hole through which a bolt to be screwed to the target device so as to fasten the oil pan to the target device is inserted, and the base portion is provided on a straight portion of the rim portion located between two of the washer portions. 7. A sealing-equipped oil pan comprising: a sealing member that is composed of an elastic member; and an oil pan that has a bottom portion, a peripheral wall, and a rim portion, the bottom portion and the peripheral wall being configured to store oil, the rim portion having a ring shape, located at an end of the peripheral wall, and provided with the sealing member, the sealing-equipped oil pan being configured to be fastened to a target device with the sealing member being interposed between the rim portion and the target device, wherein the sealing member has a projection projecting from a sealing surface configured to come into contact with the target device for sealing, and the peripheral wall of the oil pan has a base portion projecting from the rim portion and supporting the projection of the sealing member, wherein the projection of the sealing member projects in a direction intersecting a fastening direction of the oil pan in such a manner that a height of the projection of the sealing member inside the rim portion having the ring shape is larger than a height of the projection of the sealing member outside the rim portion having the ring shape, wherein the base portion has a flat portion supporting the projection of the sealing member, and the flat portion has a trapezoidal shape whose longer bottom side faces the rim portion. 8. The sealing-equipped oil pan according to claim 7 , wherein the base portion expands from the rim portion toward a region where oil is stored. 9. The sealing-equipped oil pan according to claim 8 , wherein the sealing member has a return portion located at a distal end of a side wall extending along a shape of the rim portion and projecting toward inside of the rim portion. 10. The sealing-equipped oil pan according to claim 9 , wherein the oil pan has a plurality of washer portions projecting outward from the rim portion and each having a bolt hole through which a bolt to be screwed to the target device so as to fasten the oil pan to the target device is inserted, and the base portion is provided on a straight portion of the rim portion located between two of the washer portions.
