Claims

[Scope of utility model registration request]

An upper measuring terminal attached to the upper opening end of the C-shaped arm that slides vertically without rotation and has a V-shaped tip, and a lower opening of the C-shaped arm that faces the upper measuring tip in a concentric state. A dimension measuring device, comprising: a lower measuring terminal having a fixed receiving part with an inverted square-shaped tip at an end; and a display mechanism for digitally displaying a sliding distance of the upper measuring terminal.
