PROBLEM TO BE SOLVED: To realize a sealing device for rolling bearing easily transportable and easily installed without increasing the rotating torque of a rolling bearing. SOLUTION: An outer diameter side engagement part 20 projected in the inner radial direction is installed at the base end part of a seal material 3a. The inner diameter (d) of the outer diameter side engagement part 20 is made smaller than the outer diameter D of a slinger 2a at an outer peripheral edge. By this, seal side members 1 and 3a formed by fixedly connecting the seal material 3a to a core 1 can be prevented from being separated from the slinger 2a. As a result, an operation for packing the seal side members 1 and 3a and the slinger 2a into a carrying case is made easier in the state of the seal side members 1 and 3a combined with the slinger 2a, and also the operation for installing the seal side members 1 and 3a and the slinger 2a into the rolling bearing is made easier. |
