본 발명의 특징은 상기 실린더블록(110)의 오일통로(111) 주변과 면접촉되는 베드플레이트(120)의 오일통로(121) 주변 접면부에 요홈(122)을 형성하여 접면부가 내측 접면부(123a)와 외측 접면부(123b)의 2단으로 구분되게 하고, 그러한 베드플레이트(120)의 내측 접면부(123a)와 외측 접면부(123b) 위로 실링수단(130)인 실런트의 도포나 가스켓을 설치한 것에 있다.A feature of the present invention is to form a recess 122 in the contact portion around the oil passage 121 of the bed plate 120 which is in surface contact with the oil passage 111 of the cylinder block 110, the contact portion is the inner contact portion ( 123a and the outer contact portion 123b, and the coating or gasket of the sealant, which is the sealing means 130, is placed on the inner contact portion 123a and the outer contact portion 123b of the bed plate 120. It is installed.

이와 같이 형성된 본 발명은 실린더블록(110)과 면접촉되는 베드플레이트 (120)의 접면부가 요홈(122)에 의해 내측 접면부(123a)와 외측 접면부(123b)로 분리되어 있으므로 실린더블록(110)과 면접촉될 때 그 사이에 설치된 실런트나 가스켓의 실링수단(130)을 내측 접면부(123a)와 외측 접면부(123b)가 각각 눌러주어 2중으로 눌러주는 효과를 얻게 된다.In the present invention formed as described above, since the contact portion of the bed plate 120 which is in surface contact with the cylinder block 110 is separated into the inner contact portion 123a and the outer contact portion 123b by the recess 122, the cylinder block 110. The inner contacting portion 123a and the outer contacting portion 123b respectively press the sealing means 130 of the sealant or the gasket installed therebetween when the surface contact is made.

따라서, 본 발명의 실링수단(130)은 실린더블록(110)과 베드플레이트(120) 접면부의 면압이 어느정도 떨어지더라도 실린더블록(110)과 베드플레이트(120)의 접면부를 상기와 같이 2중으로 실링된 효과를 얻으므로 오일이 누유되는 것을 최대한 방지할 수 있다.Therefore, the sealing means 130 of the present invention, even if the surface pressure of the contact portion of the cylinder block 110 and the bed plate 120 drops to some extent, the contact portions of the cylinder block 110 and the bed plate 120 are doubled as described above. The sealing effect is obtained to prevent oil leakage as much as possible.

즉, 베드플레이트(120)의 내측 접면부(123a)를 통해 누유된 오일이 있더라도 그 오일은 베드플레이트(120)의 접면부에 형성한 요홈(122)으로 흘러내려 모인 후 오일팬으로 리턴되고, 상기 요홈(122)의 외측으로 외측 접면부(123b)에 의한 실링이 또 작용하므로 설혹 내측 접면부(123a)를 통해 누유되는 오일이 있더라도 엔진의 외부에 까지 흘러나오지는 않으므로 외관상으로 전혀 보이지 않게 된다.That is, even if there is oil leaked through the inner contact portion 123a of the bed plate 120, the oil flows down into the groove 122 formed in the contact portion of the bed plate 120 and is returned to the oil pan. Since the sealing by the outer contacting portion 123b also acts on the outside of the recess 122, even if there is oil leaked through the inner contacting portion 123a, it does not flow out to the outside of the engine so that it is not visible at all. .

이상에서와 같이 본 발명은 실린더블록의 오일통로와 면접촉되는 베드플레이트의 접면부가 요홈에 의해 내측 접면부와 외측 접면부의 2열로 분리되어 2중의 실링효과를 볼 수 있고, 또한 내측 접면부를 통해 누유되는 오일이 있더라도 그 오일은 요홈으로 흘러내리게 되므로 오일이 외부로 누유되는 것을 방지할 수 있으며, 이로 인해 엔진의 외관상으로 누유되는 오일이 보이지 않으므로 소비자의 불만을 줄이고 품질에 대한 신뢰성을 높힐 수 있는 효과가 있다.As described above, in the present invention, the contact portion of the bed plate which is in surface contact with the oil passage of the cylinder block can be separated into two rows by the grooves so that the double sealing effect can be seen, and the inner contact portion Even if there is oil leaked through the oil, the oil flows down into the grooves, thereby preventing oil from leaking to the outside. This prevents oil leakage from the external appearance of the engine, thereby reducing consumer complaints and increasing reliability of quality. It has an effect.
