PROBLEM TO BE SOLVED: To provide a seal of a swiveling bearing for a construction machine that can be mounted into a seal groove and can be prevented from dropping during long use. SOLUTION: By providing seals 8 and 9 formed of elastic bodies mounted by inserting base ends 8b and 9b sides into seal grooves 10 and 11 formed in the inside periphery of the outer ring 2 of a bearing 1 and the outside periphery of the inner ring 3, providing a magnetic body on base ends 8b and 9b sides to be inserted into the seal grooves 10 and 11, and mounting the seals 8 and 9 to the seal grooves 10 and 11 by the magnetic force of the magnetic body, mounting of the seals 8 and 9 to the seal grooves 10 and 11 can be facilitated, and dropping of the seals 8 and 9 from the seal grooves 10 and 11 can be prevented by the magnetic force of the magnetic body even if used for many years. |
