The globe 100 is in the form of a sphere representing the earth and is fixed on the second rotation axis S5 and fixed on the upper side of the rotation body 80 in particular. The second rotation axis S5 is formed at a position sufficiently spaced from the first rotation axis S1 and if the first rotation axis S1 is located at the center of the earth science simulation apparatus 1 according to the present invention, S5 are biased to the edge of the earth science simulation apparatus 1 according to the present invention.

The globe 100 is rotatably coupled to the rotary body 80 about the second rotary shaft S5 so that when the rotary body 80 rotates about the first rotary axis S1, Rotates together with the rotating body 80 (the same motion as that of the earth is created), and rotates against the rotating body 80 (the same motion as the rotation of the earth is produced).

The intermediate gear 66 is rotatably engaged on the rotary body 80 about the fifth rotary shaft S3 and engages with the second connecting gear 71 and is engaged with the fourth power gear 64 to rotate The gear 66 can be rotated in engagement with the fourth power gear 64). The rotational power of the first power transmitting portion is transmitted to the second power transmitting portion while passing through the intermediate gear 66 so that the geared member 100 is rotated.

It is preferable that the number of the intermediate gears 66 is adjusted so that the rotation direction of the rotating body 80 and the rotation direction of the strap body 100 coincide with each other.

The third power transmission unit connects the second power transmission unit and the relay unit 200 so that the relay unit 200 rotates in conjunction with the rotating body 80.
