PURPOSE: A goniometer is provided to easily replace and utilize a support by using a fixing screw, thereby easily perform desired measurement. CONSTITUTION: A goniometer comprises a lower plate(10), a fixing installation unit(20), a movable plate, a first gonio(30), a second gonio(40), a third gonio(50), a fourth gonio(60), a fixing screw(70), and an adjusting tool. A magnet is installed in the lower plate. The first gonio is slide-joined to a first installation port in a forward and backward direction and is composed of a forward-backward moving body so that the forward-backward moving body is transferred in the forward and backward direction by the operation of a first screw shaft(31). The second gonio is joined to the first gonio, thereby being transferred by the operation of a second screw shaft(41). The third gonio is joined to the second gonio, thereby being rotate-transferred by the operation of a third screw shaft(51) in the forward and rearward direction along a semicircular shaped orbit. The fourth gonio is joined to the third gonio, thereby being rotate-transferred by the operation of a fourth screw shaft(61) in left and light directions along a semicircular shaped orbit(51).
