    • An arc tube is formed by a glass tube that is turned at a substantially middle thereof and wound around a spiral axis from the middle, to have a double-spiral structure. End portions of the arc tub are wound around the spiral axis. A holder has insertion openings formed therein in such shapes that correspond to shapes of the ends of the arc tube. The insertion openings allow the ends of the arc tube to be inserted along a bottom wall of the holder. The holder also includes guide grooves provided in the areas before the insertion openings in the spiral direction of the ends of the arc tube. The guide grooves allow the end portions of the arc tube to come in contact, and when the arc tube is rotated around the axis, guide the ends of the arc tube to the insertion openings.
    • 电弧管由玻璃管形成,该玻璃管在其大致中间转动并从中间围绕螺旋轴缠绕,以具有双螺旋结构。 电弧槽的端部围绕螺旋轴线缠绕。 保持器具有形成在其中的形状的插入开口对应于电弧管的端部的形状。 插入开口允许电弧管的端部沿着保持器的底壁插入。 保持器还包括设置在电弧管的端部的螺旋方向上的插入开口之前的区域中的引导槽。 引导槽允许电弧管的端部接触,并且当电弧管围绕轴线旋转时,将电弧管的端部引导到插入开口。
