Amendment 1.12.7. The name of the invention is amended as follows. Title of the invention Stopper for flip-up gate The scope of the claims for utility model registration and the brief description of the drawings are amended as follows.

[Claims for Utility Model Registration] In a flip-up gate equipped with a door that is supported by a pair of arms pivotally connected to opposing supports and opened and closed by vertical rotation of the pair of arms, the door is provided with: and a leg portion whose one end side is rotatably supported by the horizontal axis and whose other end side contacts the ground when the door is closed, and the center of gravity is set on the opposite side of the road from the horizontal axis. In addition , the ground contact position of the other end of the leg is set closer to the road than the horizontal axis, and further , the rotation of the leg toward the road is restricted to prevent the leg from falling. A stopper for a flip-up gate that is characterized by having a section.

Claims (1)

[Claims for Utility Model Registration] A flip-up gate equipped with a door that is supported by a pair of arms that are respectively pivotally connected to opposing supports and that rotates to open and close with the vertical rotation of the pair of arms, The door has a horizontal axis provided on the site side, and a leg part whose one end side is rotatably supported by the horizontal axis and whose other end side comes into contact with the ground when the door is closed, and the center of gravity is moved from the horizontal axis. The vertical position holding part is provided below and on the site side from the horizontal axis, and which restricts the rotation of the leg part toward the road side and holds the leg part in a substantially perpendicular state with respect to the ground. The characteristic flip-up gate stopper.
