PROBLEM TO BE SOLVED: To effectively drive to open/close a lens barrier with small number of parts, to reduce the power consumption of a driving motor so as to attain excellent economicity and to miniaturize not only the driving motor but also a camera itself. SOLUTION: A link member 9 is provided so as to freely rotate on a supporting shaft 8, and the lens barrier 7 is provided on the member 9, whereby the lens barrier 7 is provided so as to freely move between a front position where it interrupts a lens and a retreat position on the side of the lens. Then, a driving arm 10 is provided on the output shaft 15 of the driving motor 11 so as to freely turn centering the output shaft 15, and a recessed groove 14 extended in the radial direction of the shaft 8 or 15 is formed on either the member 9 or the arm 10 and a projecting part 16 engaged with the groove 14 is provided on the other.
