ABSTRACT:
A water tight seal structure for a camera or other device comprises a step formed in the upper end of an opening provided in the frame of the device to pass a rotating shank body which forms a movable operating member of the device. Water repellent rubber is fixedly secured to the step. The inner peripheral surface or the upper surface of the water repellent rubber is maintained in tight engagement with the adjacent surface of the shank body to prevent an ingress of water into the device.
