PURPOSE: A curvature measuring apparatus for a curved steel plate is provided to conveniently measure a curvature of the curved steel plate in a multi-direction thereof by allowing a measuring notch plate to be rotatably moved. CONSTITUTION: A curvature measuring apparatus includes a sample fixing section(40), a moving section(50), a semi-circular measuring plate and a curvature measuring plate(60). The sample fixing section(40) has a fixing pin(19) and a lifting shaft(23), to which a supporting member(20) is fixed. The moving section(50) is moved in forward and reverse directions thereof by mans of a first driving motor(7a), which is coupled to pinion gears. The pinion gears are coupled to rack gears(35,35a) installed at both sides of a table(6). The semi-circular measuring plate is rotatably fixed to a sliding plate(16), which is inserted between first and second guides(17a,17b). The curvature measuring plate(60) has a contact line(18) fixed to end portions of supporting members.
