ABSTRACT:
A lens cap has a disc-shaped cap body, a pair of sliding members opposed to each other on the cap body and slidable diametrically of the cap body, and a biasing member for biasing the sliding members in a direction in which they are extended outwardly from the cap body. The sliding members have connecting portions engageable with a connecting portion provided on the inner peripheral surface of the rim of a lens barrel. The lens cap is mounted on the lens barrel by engagement between the connecting portions. Engaging members are provided at the opposed ends of the sliding members and limit the outward extension of the sliding members from the cap body against the biasing means by mutual engagement therebetween.
