The invention discloses an invisible arc rail type seesaw. The seesaw is characterized in that six screw shafts penetrate through six circular holes and six circular roll holes in the rear surface of an arc square tube, and six circular holes in the front surface of the arc square tube; two ends of each screw shaft are fixedly connected through nuts; arc strip steel is inserted into positions among the six circular rolls; a rail formed by the six circular rolls can ensure that two ends of the arc strip steel move vertically under the effect of external force; a square vibration damping rubber plate is arranged at each of two end openings of the arc square tube; a seat plate is welded with each of two ends of the arc strip steel; a T-shaped circular tube handle is welded with the front end of each seat plate; after the components are assembled, parts below two openings of the arc square tube are fixedly buried below the ground. As the arc square tube of the seesaw is fixedly buried below the ground, the stability of the two seat plates is good when the seat plates are lifted and lowered, the area of the vacated ground between the two seat plates is the same with that of the peripheral ground, the usable site area is enlarged, the seesaw is beneficial to the implementation of other activities, all components of the seesaw are easy to machine, the size of the seesaw is relatively small after the components are assembled, and the production cost is relatively low.
