When the fixing nut 40 is coupled to the seat cone 10, the upper surface of the fixing nut 40 presses the bead 21 surface of the oil pipe 20, and the lower surface of the fixing nut 40 is washer. Combining while pressing 30. As a result, the fixing nut 40, the oil pipe 20, the seat cone 10, the washer 30, and the radiator tank 200 may be firmly coupled with only the fixing nut 40.

The first O-ring 50 is mounted on the contact surface of the first O-ring groove 17 and the oil pipe 20. In this case, the first o-ring 50 is a sealing material having a ring-shaped elasticity, and is mounted to the first o-ring groove 17 in a state of being wound on the outer surface of the oil pipe 20. As a result, a sealing material having elasticity rather than a metal material may be positioned at a contact portion between the oil pipe 20 and the seat cone 10, thereby improving airtightness.

The second o-ring 60 is mounted in the second o-ring groove 19. In this case, the second O-ring 60 is a sealing material having a ring-shaped elasticity, and is mounted in the second O-ring groove 19 to be positioned on the contact surface between the radiator tank 200 and the lower block 11 of the seat cone 10. . As a result, a sealing material having elasticity rather than a metallic material may be positioned at a contact portion between the radiator tank 200 and the seat cone 10 to improve airtightness.
