Abstract
This invention provides a structure of an apparatus case with a rotation member which can selectively restrict the rotation of a rotation bezel, rotatably mounted on a case body, in one or both of the forward and reverse directions. First and second rotation bezels are rotatably mounted on the case body, and a plate spring for restricting the rotation of the first rotation bezel is provided below the second rotation bezel. The plate spring is partly bent to rise it, thereby forming a hook. A rugged portion is formed on the lower surface of the first rotation bezel and an opening into which the hook is inserted is formed in the second rotation bezel. When the hook does not engage with the rugged portion, the first rotation bezel is freely rotatable. When the hook is inserted into the opening and is engaged with the rugged portion by rotating the second rotation bezel, the first rotation bezel is rotatable only in one of the forward and reverse directions. When the circumferential direction edge of the opening is brought into contact with the lower surface of the hook by rotating the second rotation bezel in the other direction, the hook tightly engages with the rugged portion, thereby preventing the first rotation bezel from rotating in both forward and reverse directions.
