Claims

[Scope of utility model registration request]

A seal structure for a stationary operating table comprising a bed frame, a support frame supporting the bed frame, and a base supporting the support frame rotatably around a vertical axis, the base being connected to an upper end of a surrounding wall. It consists of a base that is buried under the floor so that it is almost flush with the floor, and a base plate that is rotatably supported via a bearing built into the base.
A base cover that covers the upper end of the peripheral wall of the base from above is connected to the base plate, and an annular groove is formed concentrically with the vertical axis on the lower surface of the base cover opposite to the upper end of the peripheral wall of the base, and the annular groove is engaged with the base cover. The seal ring seals water between the upper end of the outer peripheral wall of the base and the base cover, and the annular wall that receives and supports the seal ring from the inner peripheral side is inserted into the annular groove of the base. A seal structure for a stationary operating table characterized by protruding from the upper end of a peripheral wall.
