摘要： A method of measuring a bending angle, comprising pressing a work (W), which is subjected to the measurement of a bending angle, against a rotor (9) by sliding the work (W) with the work (W) in contact with a first support member (7) constituting a reference surface, to cause the rotor (9) to be rotated around a central rotary shaft (3l) provided on a second support member (29), and measuring a bending angle by reading an angle of rotation of the rotor (9) on a detector (39), wherein a vertical position of the first support member (7) with respect to the center of rotation of the rotor (9) is regulated during this time so that the center of rotation is positioned within a range (R) in which the work (W) and rotor (9) contact each other, calibration being carried out prior to the measurement of the bending angle by rotating the rotor (9) so as to bring a projection (33) into contact with a stopper (35) provided on the second support member (29), whereby an easy, speedy and highly accurate bending angle measuring operation can be carried out by using a small-sized lightweight apparatus.
