A radial oil seal structure is provided to secure the sealing compression force against the variation of oil compression pressure acting on the oil seal. A radial oil seal structure comprises a main rib(3) and a sub rib(5) which are integrally formed on a seal housing(1) comprising a horizontal part(17) and a vertical part(19), a spring(9) installed on the inner diameter part of the main rib, an oil pressure control rib in which an oil outlet(15) is formed on a partition(11) extended from the spring, and a mounting part formed on the outer diameter part of the main rib. The partition forms an oil chamber(13) between with the seal housing. |
