Abstract
An opening and closing device opens and closes a shielding body that partitions space by the operation of an operating unit in a range between a fully opened position and a fully closed position. The opening and closing device includes a limit setting unit, a control unit, and an operating element. The limit setting unit can perform an operation for setting an operational limit position of the shielding body. The control unit sets a range, where the shielding body can be opened and closed by the operation of the operating unit, as a predetermined range between the set operational limit position and a fully closed position or between the set operational limit position and a fully opened position. The operating element operates the control unit so that the range where the shielding body is opened and closed is set to the predetermined range.
