Abstract
Disclosed is a waterproof camera in which a watertightness of an interior of a camera body or a lens tube is maintained during a state where zooming is not performed by a zooming knob defined as a zooming manipulation member. When the lens tube is advanced and retracted by zooming, although the zooming knob is manipulated, a gap serving as an air hole is formed with this manipulation, and the interior of the camera body or the lens tube communicates with the outside air. This prevents such a state that a drive resistance of the lens tube increases. The camera does not require a special filter or the like as provided in the prior art waterproof camera, the filter being disposed in the gap serving as the air hole.
