Claims

[Scope of utility model registration request]

Along the left and right axial edges of the opening provided in the cylinder, vertical reinforcing members having a cross-sectional area equal to or larger than the cross-sectional area of the cylinder due to the opening are extended from the upper and lower peripheral edge positions of the opening. A cylindrical opening structure characterized in that the upper and lower ends of each longitudinal reinforcing member are connected to reinforcing rings arranged on the outer peripheral surface of the cylinder to sandwich the opening.
