PROBLEM TO BE SOLVED: To smoothly move panel bodies and to prevent the panel bodies from inclining in an expansion fence for a base-isolated structure comprising two panel bodies provided in a movable manner. SOLUTION: The expansion fence 1 for the base-isolated structure is provided with the base isolation side panel body 40 and the non-base-isolation side panel body 50 which are arranged in parallel in the mutually overlapped state from the tips to the center parts and movable forward and backward in a longitudinal direction. Base isolation side rollers 60 are protrusively provided near the tips of an upper frame 41 and a lower frame 42 of the base isolation side panel body 40. Non-base-isolation side rollers 70 are protrusively provided near the tips of an upper frame 51 and a lower frame 52 of the non-base-isolation side panel body 50. The surfaces, facing the non-base-isolation side panel body 50, of the upper frame 41 and lower frame 42 of the base isolation side panel body 40 are formed with base isolation side guide grooves 48, and the surfaces, facing the base isolation side panel body 40, of the upper frame 51 and lower frame 52 of the non-base-isolation side panel body 50 are formed with non-base-isolation side guide grooves 56.
