Abstract
A warning structure includes a bracket and a warning member mounted on the bracket. The bracket includes a main body, rollers rotationally mounted to the main body, and a stopping assembly including a support member, a mounting member, and a resilient member. The support member is coupled to the main body. The mounting member is movably mounted to the support member. The rollers are mounted to the mounting member and the main body. The resilient member elastically resists the support member and the mounting member to bias the mounting member. When the support member is subjected to a downward force, the support member abuts against a ground to keep the bracket stationary.
