口部開閉装置。 It is equipped with a base block having a slope-shaped opening, a sealing plate fixed to a rotation shaft installed on the base block via a rotation arm, and a sealing plate rotation drive mechanism. In opening/closing operation,
The opening is opened and closed by the sloped shape of the opening and the rotation movement of the sealing plate around the rotational axis relative to the slope of the opening, thereby minimizing the effective operating space for opening and closing the opening. An opening opening/closing device characterized by:
