Abstract.  This paper describes the latest status of the fabrication and testing of a sub-scaled tokamak model for the vibration test to validate numerical analysis on seismic response of fusion reactor. The sub-scale model referred to the 1998 ITER design and the scale was decided as to be 1/8 considering the capacity of test facility and the scaling ratio was chosen so that the stress becomes equivalent to that of the real machine. The partial test had been performed with the gravity supports and TF coil case, and their vibration characteristics were verified.
