    • An accessory and an accessory for an image pickup apparatus are provided and are advantageous in reducing cost by reducing the number of parts. A retaining ring is engaged in an annular groove formed in an outer circumference of a cylindrical part of a wide-angle converter lens. Each of retaining ridges has a bottom wall extending from the inner circumference of the annular part in the direction of the width of the annular part in a recess, and a protruded wall extending radially outward of the annular part from the end of the bottom wall, spaced from the annular part, and protruding radially outward from the first outer circumference. When the parts, provided with the retaining ridges, of the annular part are depressed radially inward of the annular part, the protruded wall sink radially inward from the first outer circumference.
    • 提供了用于图像拾取装置的附件和附件,并且通过减少部件的数量来降低成本是有利的。 保持环接合在广角转换器透镜的圆筒部的外周形成的环状槽中。 每个保持脊具有从环形部分的内圆周沿着环形部分的宽度方向延伸到凹部的底壁,以及从底壁的端部沿环形部分径向向外延伸的突出壁, 与环形部分间隔开,并且从第一外圆周径向向外突出。 当具有环形部分的保持脊的部分被径向向内压向环形部分时,突出的壁从第一外圆周径向向内凹陷。
