PROBLEM TO BE SOLVED: To provide an improved skeleton connection bracket capable of preventing sand or small stones from being caught between a bracket and a skeleton member such as a scissors assembly body connected to the bracket, a support, or a roof support member to smoothly slide or rotate each member. SOLUTION: In a canopy structure in which skeleton members such as a support, a scissors assembly body, and a roof support member are mutually connected and made collapsible by the scissors assembly body that two bars are rotatably connected together to form a letter X and made pantographically collapsible and a fixed bracket including the skeleton members such as the roof support member and the support and fixed to the upper part of the support, and a slide bracket slidably inserted in the middle of the support, irregularities are formed at the inside face of the scissors joints and the roof joints connecting the the ends of fixed bracket and the slide bracket and the scissors assembly body or the roof support member to prevent, foreign materials such as sand from being caught between each joint and member.
