PURPOSE:To prevent the leak of the discharged oil from the divided surface by sealing the gap part by the sealing air supplied from a groove formed onto the divided surfaces of a bearing housing. CONSTITUTION:Sealing-air feeding holes 7 and 8 are connected onto a divided surface 1, and a groove 10 is formed so as to pass between an oil discharging chamber 9 and a fastening-bolt hole 2. In other words, even if the abnormal reduction of the contact surface pressure or the generation of gap is generated in the metal touch part of the divided surface, the sealing air supplied from a groove 10 part seals the gap part, and the trouble of leak of the discharged oil outside can be eliminated, by forming the sealing-air groove part 10 onto the divided surface 1. |
