    • In an assembling method of an optical deflection apparatus in which a polygonal mirror is fixed on an outer ring of a radial bearing and an optical scanning is conducted by a rotation of an inner ring of the radial bearing, the assembling method includes the steps of placing the polygonal mirror on the outer ring of the radial bearing wherein the polygonal mirror and the outer ring of the radial bearing have an engagement portion including an adhering portion with a gap having a distance between the polygonal mirror and the outer ring of the radial bearing; adjusting a tilt angle of the polygonal mirror with respect to the outer ring of the radial bearing; and filling an adhesive in the gap of the adhering portion under the adjusted condition, thereby integrally fixing the polygonal mirror and the outer ring of the radial bearing.
    • 在其中多面镜固定在径向轴承的外圈上并且通过径向轴承的内圈的旋转进行光学扫描的光学偏转装置的组装方法中,组装方法包括以下步骤: 所述径向轴承的外圈上的多面镜,其中所述多角镜和所述径向轴承的外圈具有接合部分,所述接合部分包括具有在所述多角镜和所述径向轴承的外圈之间具有间隔的间隙的粘附部分; 调节所述多面镜相对于所述径向轴承的外圈的倾斜角度; 并且在调节状态下在粘合部分的间隙中填充粘合剂,从而整体固定多角镜和径向轴承的外圈。
