ACCESSORY, AND ACCESSORY FOR IMAGING DEVICE

摘要

Provided are an accessory advantageous for reducing the parts count and the cost, and an accessory for an imaging device. A retaining ring (36) is mounted in an annular groove (52) of the outer circumference (34) of a cylindrical portion (32) of a wide conversion lens (30). A retaining pawl (54) is constituted to include a bottom wall (5402) extending in a notched portion (43) widthwise of the annular portion (52) from the inner circumference of an annular portion (52), and a projecting wall (5404) extending radially outward of the annular portion (52) from the leading end of the bottom wall (5402) and projecting radially outward of a first outer circumference (3802) at a portion spaced from the annular portion (52). The projecting wall (5404) undergoes displacement radially inward of the first outer circumference (3802), when the portion of the annular portion (52) having the retaining pawl (54) is displaced radially inward of the annular portion (52).
