PURPOSE: To prevent the movement of a tent by forming a weight having a slit receiving a tent post from the peripheral surface side of a cylindrical body into a hollow section, and providing a slipping stopper to prevent the slippage of the weight in the direction of the slit.

CONSTITUTION: A weight 10 equipped with a slit 14 receiving a tent post from the peripheral surface 12 side of a truncated cone shaped cylindrical body 11 into hollow section 13 and a recessed groove 16 from the upper surface 15 of the cylindrical body 11 in the downward direction is formed. After that, a columnar slipping stopper 20 fitted to a space section 18 having an approximately hexagonal section consisting of a part of the slit 14 of the weight 10 and the recessed groove 16 formed in the slit 14 is provided. Then, the tent post is loaded to the inside of the hollow section 13 of the weight 10 downward from the upper surface 15 of the cylindrical body, and the slipping stopper 20 is inserted into the space section 18. According to the constitution, stabilized moving prevention efficiency can be exhibited.
