In a grease-sealed double-row rolling bearing that is sealed by a plate, a small gap is formed at the end of the inner diameter surface on the sealing plate side of the retainer with the outer diameter surface of the inner ring, and a small gap is formed on the outer surface inclined surface to form a small gap at the tip. What is claimed is: 1. A grease-sealed double-row rolling bearing characterized in that an annular projection with a tapered cross section is provided, and a grease reservoir recess is provided between adjacent pockets of a retainer. (2) The grease-sealed double-row rolling bearing according to claim 1, wherein the grease reservoir recess is an axial recess formed between adjacent pockets on the inner diameter surface of the cage. (3) Utility model registration claim 1, characterized in that the grease reservoir recess is an axial recess formed between adjacent pockets on the inner diameter surface of the cage, and a portion thereof opens on the outer diameter surface of the cage. Grease-sealed double-row rolling bearings as described in . (4) The grease-sealed double-row rolling bearing as claimed in claim 1, wherein the grease reservoir recess is an axial slit that divides the cage between adjacent sockets.
