摘要： A rolling bearing apparatus includes inner rings, an outer ring, and sealing devices each having a seal case fixed to the outer ring. The seal case includes a fixing portion press-fitted in the outer ring, and a ring-shaped portion extending radially inwardly from an axially-outer end of the fixing portion. The fixing portion has a ridge formed on and projecting radially outwardly from an outer peripheral surface thereof. The ridge is disposed nearer to the axially-outer end of the fixing portion than an axially inner end of the fixing portion.
