PROBLEM TO BE SOLVED: To increase the assemblability of a sealing type rolling bearing in which a dust cover is fitted to the fitting part of a bearing raceway to a mounted member into the mounted member. SOLUTION: A first fitting part 13 for fitting the tube part 61 of the dust cover 60 and a second fitting part 14 fitted to a shaft 2 are formed on the inner peripheral part 12 of the inner ring 10, and the second fitting part 14 is more projected to the radial inner side than the first fitting part 13. Since a frictional force between the dust cover 60 and the shaft 2 is lowered when the bearing is assembled on the shaft 2, the displacement of the position of the dust cover 60 can be suppressed to increase the assemblability of the bearing. In particular, when the second fitting part 14 is more projected to the radial inner side than the tube part 61 of the dust cover 60, the dust cover 60 does not in slidable contact with the shaft 2 and the displacement of the position does not occur in assembling the bearing.
