摘要： A lens including: a lens body having first and second surfaces; a flange part formed to protrude from a periphery of the lens body and to have a cylindrical outer circumferential surface; a lens installation surface formed at an outer edge part of the flange part; a recessed part formed as a part of the flange part such that a part of the cylindrical outer circumferential surface is recessed toward the optical axis; and a gate root part located at a central part of the recessed part. The gate root part has a flat surface which is in a same level with respect to the lens installation surface. The gate root part lies on an optical axis side with respect to a virtual curved surface formed by extending the cylindrical outer circumferential surface through the recessed part.

摘要翻译： 一种透镜，包括：具有第一和第二表面的透镜体; 凸缘部，其形成为从所述透镜体的周边突出并具有圆筒状的外周面; 形成在所述凸缘部的外缘部的透镜安装面; 凹部，其形成为所述凸缘部的一部分，使得所述圆筒形外周面的一部分朝向所述光轴凹陷; 以及位于凹部的中心部的门根部。 门根部具有相对于透镜安装表面处于相同水平面的平坦表面。 门根部相对于通过凹部延伸圆筒形外周面而形成的虚拟曲面位于光轴侧。
