  Next, the structure of the seismic isolation experience device 10 will be described with reference to FIGS. 4 and 5. As shown in FIGS. 4A and 4B, the seismic isolation experience device 10 according to the present embodiment is fixed to the base 11 so that the base 11 can extend and contract in the vicinity of the wheel 16 described above. A jack 17 is provided, and after the seismic isolation experience device 10 is moved to a predetermined position by the wheel 16, the seismic isolation experience device 10 can be fixed at the predetermined position by extending the fixed jack 17.

  Mounted on the base 11 is a vibration generator 12 including a drive source 12a such as a motor and a conversion unit 12b that converts rotational motion input from the drive source 12a into linear motion. Further, as shown in FIG. 5, a pair of motion guide devices 12d, 12d and 12e, 12e arranged substantially in parallel around the drive source 12a and the conversion unit 12b are substantially in a cross-beam shape so as to be substantially orthogonal to each other. It has an arranged guide. The ends of the pair of motion guide devices 12d, 12d and 12e, 12e are fixed by frame bodies 12f, respectively.

In addition, vibration is applied to the frame body 12f along the depth direction y. By being configured in this way, the seismic isolation experience device 10 according to the present embodiment vibrates the bottom surface side of the seismic isolation device 15 by the vibration generating device 12 in response to a command from the vibration control unit 14. Reproduce the shaking. The moving member of the motion guide device 12e is formed with an insertion hole 24a through which a switching means 24 described later is inserted. Furthermore, the vibration generator 12 is not limited to reciprocating motion along the width direction x and the depth direction y, and can also reproduce the so-called earthquake pitch by, for example, vibrating in the vertical direction.

  Next, as shown in FIG. 4B, above the vibration generator 12, a pair of lower motion guide devices 21a and 21a attached to a bottom plate (not shown) are substantially parallel along the width direction x. As shown in FIG. 4 (A), a pair of upper motion guide devices 21b and 21b arranged in a substantially cross beam shape so as to be substantially orthogonal to the pair of lower motion guide devices 21a and 21a described above are arranged.
