Claims

[Scope of utility model registration request]

In an inclination measuring device that measures the degree of inclination of a drawn string stretched linearly from a first position to a second position with respect to a predetermined reference line passing through the first position, the slope is measured from the first position along the drawn string. A member to be measured having a pin hole at a position separated by a predetermined distance A is movably arranged in a plane perpendicular to the pulling string, the pulling string is inserted through the pin hole, and the surrounding area of the member to be measured is Detecting means for detecting the deviation movement amount Δx, Δy from the reference line by contacting the member to be measured is provided in at least two places, and the detection means detects the deviation movement amount Δx, Δy from the reference line, and the A device for measuring the inclination of a drawn thread, characterized in that the degree of inclination and the direction of inclination of the thread with respect to the reference line are measured.
