PROBLEM TO BE SOLVED: To prevent wear of a seal ring of a device feeding into a partition. SOLUTION: In a device feeding into a partition to guide a shaft 13 especially like an ocean ship propeller shaft onboard, at least two seal rings are provided to this device. Each ring has substantially L-shape and is mounted on the shaft 13. In the mounted condition, free ends 21 of seal ring leg parts 18 extending along a shaft direction contact each other and those rings enclose the shaft 13 around the free end 21 under pressurized condition. Free ends 22 of legs 19 extending in a radial direction are elastically locked with surfaces 23 of side walls 12 extending in a radial direction of a housing 5 facing each other. The legs 19 extending in the radial direction are slightly separated and take oblique positions against the shaft 13 when viewed from the shaft 13. |
