Abstract
A dry type cleaning case is for cleaning an object with a medium that flies by a revolving airflow. The dry type cleaning case includes a case unit and a leakage prevention unit. The case unit includes a space in which the medium flies, an opening that contacts the object so that the medium collides with the object, a ventilation path through which air flows into the space from outside, a suction opening that suctions the air that has been guided into the space through the ventilation path, to generate the revolving airflow in the space, and a porous unit through which a substance removed from the object is passed to the suction opening. The leakage prevention unit prevents the medium from leaking outside through the opening from the space, by causing outer air to flow in when the case unit is separated from the object.
