PROBLEM TO BE SOLVED: To deal with a temperature rise owing to an increase in the lubrication lifetime, preventing the costs from increasing without changing the material of grease and the other component with the conventional one in view of a practical use that it is necessary to take measures to deal with the temperature rise in a rolling bearing for an alternator involving the tendency to increase electric capacity of the alternator. SOLUTION: A grease reservoir 14 is installed along both sides of a track groove 4 of an outer ring 2 in a rolling bearing for the alternator, which can repeatedly contribute to the lubrication action by containing grease on the grease reservoir 14.
