  "textContent": "The present invention relates to a nonrotating billboard of a rotation body which is attached on a surface of a rotation center of a vertical rotation member such as vehicle wheel (100), fan, etc. for thereby showing a nonrotating state of a pattern, emblem or advertisement irrespective of a rotation of a rotation body. The nonrotating billboard of a rotation body includes a housing (10) attached to a center of a rotation body and rotated together with the rotation member, a billboard member (20) which has a surface on which a billboard is formed and includes a weight member (21) below the weight center and is installed in the housing based on a relative rotation method and maintains an upright state by the weight of the weight member, and a friction prevention unit (12,22,32) for maintaining a free state of the billboard member from the housing in a nonrotating state by preventing the billboard member from being contacted with the housing. Therefore, the nonrotating billboard of a rotation body according to the present invention is attached to a surface of a rotation body such as a vehicle wheel or a fan for thereby implementing a clear nonrotating billboard such as a pattern, advertisement or an emblem of a fabrication company irrespective of a rotation of the rotation body.",
