PURPOSE: To obtain a slalom device for a body to feel a state nearly moving in a space by providing a sliding body discharge port in the upper end part of an inclined face, where an elastic body is arranged to react at the time of contact, and providing a conveying track, which houses a person and to collect the sliding body to the discharge port, in a lower end part.

CONSTITUTION: A sliding body 13 discharged from a sliding body discharge port 4 to an inclined face 3 arrives at the lower end part of the inclined face 3 while colliding with an elastic body 2 or meandering in an interval to the elastic body 2. Then the sliding body 13 is guided to a sliding body collecting port 9 by a guide wall 10 and carried from the port 9 to a sliding body lift 12 along a conveying track 11. Further, the sliding body is carried from a sliding body traveling rail 5 to the arbitrary discharge port 4 and discharged again to the inclined face 3. In the middle of the conveying track 11, the person gets on/off the sliding body 13 on getting-on/off platforms 7 and 8. The sliding body 13 is spherical. Then the frame of the sliding body is formed with steel or resin material, etc., and a surface 14 is formed with a transparent material. On the bottom of the sliding body, a controller 18 is arranged and an weight, which can be made eccentric corresponding to the inclination of the sliding body 13, is provided or a device to freely protrude or pull-in a brake to an external part. Thus, the dummy experience of spatial action can be easily enjoyed on the ground.
