PROBLEM TO BE SOLVED: To provide a method for fixing a shield plate capable of maintaining the roundness of a race ring constant after the shield plate is fixed, by reducing a caulking force applied to the shield plate and eliminating a deformation amount of the race ring in caulking. SOLUTION: In this shield plate fixing method, metallic shield plates 12a, 12b are caulked and fixed to seal grooves (outer ring seal grooves Gs) formed on race rings (outer ring 4, inner ring 6) relatively rotatably incorporated in a bearing (ball bearing 2) by a caulking die 14 of a predetermined caulking tool T. The shield plate is caulked and fixed to the seal grooves by applying a caulking force to the shield plate from the caulking tool while swinging one of the caulking tool and the race rings relative to the axis Ax of the race ring at a predetermined swing angle α.
