PROBLEM TO BE SOLVED: To provide an inexpensive half angle measuring device with simple equipment, capable of measuring the half angle of a V-belt without requiring labor and technology for measurement like a conventional type. SOLUTION: This device is provided with a tilt angle sensor 2, a measurement base 3 fitted with a reference member 4 forming a reference surface for placing the V-belt, a belt fixing member 5 for fixing the V-belt on the reference surface, a supporting member 6 for longitudinally supporting a part of the back surface of the V-belt developed circularly in a flat state by a prescribed length, an energizing member 7 for pressing the V-belt so as to make the V-belt positioned along the supporting member 6, a zero point setting member 8 for performing the zero setting of the sensor 2, and an adaptor 9 for supporting the sensor 2 so as to make the sensor 2 abut along the surface to be measured of the V-belt.
