置に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a case in which the side wall of the case portion has a groove for accommodating the irregular cross-section sealing piece, and this groove is formed in the sealing area by the side wall and a protective collar protruding from the side wall. A rubber elastic sealing device between two separable case parts, in which the irregular cross-section sealing piece is in contact with the side surface of the groove, but is layered from the bottom of the groove, especially for a transmission case for a vehicle drive device. It relates to a sealing device between the oil pan and the oil pan.

に密封して裁っている。Such a rubber-elastic sealing device is known from US Pat. No. 2,914,038, which has a groove in one of the case parts formed by the side walls for accommodating a sealing piece of irregular cross-section. It is inserted into the groove of the bearing ring and is sealed and cut on the contact surface bent outward from the side wall of the oil pan by a pressure fit.

油受は密封装置が保証されなＩ／１という欠点を持って
いる。As is well known, oil pans are made from sheet steel or light alloys, and the inherent strength of this material prevents leakage in the sealed area when the oil pan is assembled with adjacent case parts with the interposition of a sealing piece of irregular cross-section. Due to the increasing requirements regarding corrosion, weight reduction and structural diversity, plastic oil pans have been proposed to replace the common oil pans. However, due to the spaced mounting screws, a well-functioning oil pan has the disadvantage of I/1, where a seal is not guaranteed.

片部分が支持力を直接側壁へ導入する。Due to the special sealing device between the case parts, the spreading force of the groove is made as small as possible, and the supporting force of the irregular cross-section sealing piece is
This is caused by the modified cross-section sealing section which cuts over the lower housing part without going through the groove sides or the groove bottom, which introduces the supporting force directly into the side wall.
異形断面密封片がＬ字状に形成され、短い方の一辺が側

されている。A sealing piece 3 of irregular cross section is provided between the two case parts, that is, the transmission case 1 of the automatic transmission system and the vehicle drive system oil receiver 2 made of plastic, for elastic sealing. As shown in the figure, it is inserted into a groove 4 which serves to accommodate the sealing piece.

' covers the side wall 5, and one side 3a that enters the groove 4 is separated from the groove bottom 4a, but is in contact with both groove side surfaces 4b. The irregular cross-section sealing piece 3 has two elevations 7.8 of approximately semicircular cross section extending parallel to the longitudinal direction, via which the transmission case 1 is supported. These ridges 7,8
are positioned such that the i-side ridge 7 is above the groove 4 and the other ridge 8 is above the side wall 5. In this case, the supporting force is introduced directly into the side wall 5 only via the ridge 8. Since one side 3a in the groove 4 can escape toward the groove bottom 4a and therefore has no supporting force, no force to spread the groove 4 is generated.
