PURPOSE: A seesaw assembly is provided to rotate and operate by making a bottom unit and a top seesaw material which added to the rotating material rotates with a 360-degree by a gear formed to housing. CONSTITUTION: A seesaw assembly capable of rotating and operating up-and-down comprises a fixing material(5) added housing which combines rotating material on the top center side of base plate(1); a rotating material which rotates in a 360-degree at one-way direction; a bottom see-saw material(20) installed in a width direction by a shaft at the bottom through-hole formed on the rotating material; and a top see-saw material(30) combined in a longitudinal direction by a shaft at the top through-hole formed on the top portion of rotating material. The housing adds bearing which smoothly rotates rotating material in the bottom of inside cylindrical tube body and forms several gears at a same interval on top. |
