The present invention relates to a vertical rotary parking facility having shaking prevention pallets, which connects guide groove members in a caterpillar track in a simple structure to prevent shaking of pallets by movement and entry of top and bottom guide rollers. The parking facility comprises: a frame vertically and horizontally connected at the front and the back to form a pair of frameworks; a driving unit including a motor installed on the frame, sprockets rotated by the motor and installed in pairs at the top and bottom of the frame to correspond to each other, two rows of chains connected to the pair of sprockets in a caterpillar track, and a plurality of hanging members installed on the chains to be separated from each other; hanger units rotatably installed on the top of a pair of the hanging members corresponding to each other; pallets installed on the hanger units, respectively; and a shaking prevention unit which is installed on the frame and prevents shaking of the hanger units. The shaking prevention unit includes: guide groove members separated at regular intervals along the circumference of the chain on one side and arranged in a caterpillar track; a plurality of installation members connected between the guide groove members and the frame; a vertical support member arranged vertically, wherein the bottom thereof is mounted on the outside of the top of the hanger units penetrating the top of the hanging members to protrude to the outside; and a guide roller installed on the outside of the top of the vertical support member to be horizontally rotated, and slidably inserted into the guide groove members.
