PROBLEM TO BE SOLVED: To improve reliability by strengthening engagement of one protective member with other protective members without reducing assembling property in a lens barrier device for protecting a front surface of a lens barrel.SOLUTION: A second protective member 52B is rotated with a first protective member 52A rotational axis as a center and at least one of the first and second protective members enables elastic deformation. A restriction member 52B5 for restricting movement in the direction of the rotational axis of the first protective member is provided in the second protective member. The restriction member is engaged to the first protective member by elastic deformation of at least one of the first and second protective members and restricts the movement in the direction of the rotational axis of the first protective member. |
