Kind Code:
A1
Abstract:
The present invention is provided with: a cap body that has a blocking part covering the lens from the optical axis direction and that is removably attached to a lens hood which is located at an end in an optical axis direction of a unit body having a lens disposed therein and which has an engagement groove extending in a direction around an optical axis; a plurality of engagement members that each have an engagement lug capable of engaging with the engagement groove, and are located and separated from each other in the direction around the optical axis in a state that allows the plurality of engagement members to move relative to the blocking part in a direction perpendicular to the optical axis; and an inner cover that is located on the opposite side from the blocking part with the engagement member interposed therebetween in the optical axis direction. The greatest one of the angles between the adjacent engagement lugs in the direction around the optical axis with respect to the center of the blocking part is smaller than the angle between both ends of the engagement groove in the direction around the optical axis with respect to the center axis of the lens hood.
