<P>PROBLEM TO BE SOLVED: To provide a rolling bearing device facilitating assemble work of components, and continuously stably supplying grease base oil sealed in a grease reservoir to a raceway surface of a fixed side bearing ring. <P>SOLUTION: A grease reservoir moulding 3 has: a body part 14 fitted to a spacer 2; and a hollow clearance forming piece 15 extended from the body part 14 to a stepped surface 5b side and forming a flow passage between its peripheral wall and an outer ring 5 by being opposed to the stepped surface 5b at its tip end via a clearance δ1. A slipping-out preventing piece 18 having a protruding part 18a protruding to a radial direction is formed on a fitting surface of the body part 14 to the spacer 2. The slipping-out preventing piece 18 prevents the spacer 2 from slipping out of the body part 14 in the state where the body part 14 is fitted to an inner peripheral surface of the spacer 2 on the bearing space side. <P>COPYRIGHT: (C)2010,JPO&INPIT |
