摘要：
Disclosed is an improved casing for containing cameras, videocameras, flashlights, portable radios and other articles which can be used in scuba diving. It is designed to cause the inner pressure of the casing to vary and balance with the surrounding water pressure. It is guaranteed free from deformation, collapse or water invasion in underwater use without using thick strong wall or frame structure.
