Abstract
PURPOSE:To eliminate the need to rotate a disc for centering, by a method wherein a centering plate having an outer peripheral edge being the diameter of a mating line is joined under a microscope with an encoder disc body having a mating line for centering. CONSTITUTION:An outer peripheral edge 21 of a centering plate 2 is coincided with a mating mark 11 of a disc body 1, and in this case, a plurality of recessed parts 22 in the outer peripheral edge 21 are a measure for positioning. The outer peripheral edge 21 and an inner peripheral edge 24 are completely in a concentric relation, and after the position of a joint can be confirmed, an adhesive is poured in the recessed parts 22 for joining and securing. The circle of a pattern 13 for signal on the disc body 1 is concentric to that of the inner peripheral circle 24 of the centering plate 2. The inner peripheral edge 24 is formed so as to have a size coincided with the outer size of a hub insertion part, and is so sized to be insertable without any looseness. After an adhesive is poured in the recessed parts 23, centering is effected, and the plate 2 is securely joined with the hub.
