Claims

[Scope of utility model registration request]

A steel belt is provided coaxially on both ends of a winding drum around which the tent is wound so as to be able to be wound up and let out, and connected to both ends of the tent's unwinding edge side. The tent expansion device is equipped with a belt take-up pulley and extends and stores the tent, wherein the take-up drum is equipped with a drive motor coaxially, and the motor rotation shaft and the take-up drum are connected to each other by a motor adapter. The winding drum is divided into left and right by connecting through the cylinder, and a cylinder is connected and supported coaxially through a cylindrical ring in the left and right partitions, and a cylinder is connected between the ends of the left and right cylinders and the winding drum. A tent expansion device comprising: a shaft portion of the belt take-up pulley rotatably fitted therein; and a torsion coil spring interposed between the shaft portion and the cylindrical ring.
