PROBLEM TO BE SOLVED: To provide a movement restricting device protecting seaweed seeds and seedlings adhering onto a pillar-like part from vermin damage of sea urchin in a seaweed bed creating technique using as the core, seaweed seeds and seedlings adhering onto a pillar-like part arranged in a standing condition on a base, and to provide a structure for seaweed bed creation using the device so as to create a further secured seaweed bed. SOLUTION: The movement restricting device 6 composed of a support body 4 and many cord-like bodies 5 is installed on a prescribed height position of a column-like part 3 arranged in a standing position on a base 2. A plurality of seaweed seeds and seedlings 8 integrated with a plastic ring-like base body 7 are attached to an outer peripheral surface above the movement restricting device 6, at an interval in the height direction through the ring-like base body 7. In this case, the mounting position of the support body 4 is set so as to make the lower ends of the many cord-like bodies 5 nearly reach the upper surface of the base 2, and obstruct sea urchin 9 from creeping up. With a boundary of the position of the support body 4 of the movement restricting device 6, the above column-like outer peripheral surface is used as a raising bed of the seaweed 8.
