Claims

[Scope of utility model registration request]

A main scale scale and a main scale reading character are provided on the outer circumferential surface of the sleeve and are located on one side of the sleeve and directed in the axial direction of the sleeve, and the simple main scale scale is rotatably fitted to the sleeve. In a micrometer in which a vernier scale and vernier reading characters are provided on the outer circumferential surface of the side end portion toward the circumferential direction of the simple, the outer circumferential surface of the sleeve includes:
A second main scale scale and a second main scale read character are provided in symmetry with the front whisker main scale scale and the main scale read character with respect to the axis of the sleeve, and the vernier scale read character is provided on the outer peripheral surface of the simple. A micrometer with a dual scale, characterized in that a second vernier scale reading character is provided near the main scale scale for reading the value between the main scale marks of the famous confectionery 2.
