PROBLEM TO BE SOLVED: To provide a cage for a rolling bearing having superior mechanical characteristics, and hardly causing deformation even when it is used in a rolling bearing used in a high temperature of 150°C or more, and in high speed rotation wherein a product of a pitch circle diameter of the rolling bearing and a rotational speed of the rolling bearing is one million or more. SOLUTION: The cage 10A for the rolling bearing is composed of polyamide-imide resin containing 10-40 mass% glass fiber with an average fiber diameter of 3μm to 30μm. COPYRIGHT: (C)2007,JPO&INPIT
