| 主权项 | 1. A rotary wheel having a circular disc shape, comprising: a luminescent light emitting area in which a luminescent material is provided along a circumferential edge of the circular disc shape; an annular step portion which is formed at a different level from a reference plane which is a surface where the luminescent light emitting area is formed; and a balance correction material which is placed at the annular step portion, wherein the annular step portion comprises an annular rear surface step portion which is formed along the circumferential edge of the circular disc shape on an opposite side of the rotary wheel from a side of the surface where the luminescent light emitting area is provided, wherein the rear surface step portion is formed on an outer circumferential side of the luminescent light emitting area, and wherein the balance correction material is placed at the annular rear surface step portion so as to even a rotational balance when the rotary wheel is rotated. | ||
