PROBLEM TO BE SOLVED: To provide a lens cap that can improve influence of a backlash arising from a play between a support part and a barrier on an interspace between each barrier in a state where an inner side of a mount part is sealed.SOLUTION: A lens cap 50 to be mounted to a lens barrel 13 provided with a movable lens barrel 40 allowed to extend from a fixation tube 35 toward a photographing optical axis OA direction and retract into the fixation tube 35 comprises: a circular mount part 51 for being mounted to the fixation tube 35; a plurality of barriers 52 that covers a tip of the movable lens barrel 40 while sealing the inner side of the mount part 51; a plurality of support parts 53 that is provided at the mount part 51 for individually supporting each barrier 52 rotatably around an open/close axis line (56) orthogonal to the photographing optical axis OA direction; and a pressing mechanism 80 that is provided at each support part 53 for individually giving each barrier 52 pressing force toward one of the directions of the open/close axis line of each support part 53 in which each barrier 52 is configured to be rotatable. |
