The present invention comprises a hub member (8) that is attached to a rotating shaft (11), and a circular scale plate (5) that is fixed to the hub member (8) by an adhesive (19) and has, on the frontsurface thereof, a pattern (14) comprising a high-reflection part (141) having high light reflectivity and a low-reflection part (142) having low light reflectivity. A step (23) is provided at the outer circumferential part of the hub member (8). The outer diameter of the scale plate (5) is made to be larger than the outer diameter of the outermost circumferential part of the surface (17) of thehub member (8) where the scale plate (5) and the hub member (8) are adhered to each other. 具备：毂部件(8)，安装于旋转轴(11)；以及圆形型的标尺板(5)，通过粘接剂(19)固定到毂部件(8)，并且在表面具有由光的反射率高的高反射部(141)和光的反射率低的低反射部(142)构成的图案(14)，其中，在毂部件(8)的外周部设置有台阶(23)，标尺板(5)的外径大于毂部件(8)中的标尺板(5)和毂部件(8)的粘接面(17)的最外周部处的外径。
