Abstract
The present invention provides a seal for rolling bearings having improved sealing properties, undergoing no separation between a core and a peripheral portion nor deformation even in long-term use. The seal comprises a flexible resin portion which comes into contact with an outer race and a rigid resin portion which is more rigid than the flexible resin portion, the rigid resin portion and the flexible resin portion being fusion bonded together into an integral body.
