Abstract
An underwater housing has a housing body of which a bottom is open and a lid is fitted to the bottom opening in watertight fashion. A manually operable dial is rotatably mounted on an upper side of the housing body in such a manner that a portion of the manually operable dial projects from a rear side of the housing body. A driving gear is formed on a lower side of the manually operable dial, and is in mesh with a driven gear. Within the housing body, a coupling gear is formed coaxially on the driven gear. When the manually operable dial is rotated in a first direction, the coupling gear is rotated in a second direction, and causes a wind-up dial of a camera to rotate in turn in the first direction, that is, in the same direction as the manually operable dial. The manually operable dial is prevented from rotating in the second direction by a reverse-rotation-preventing member.
