Abstract
A machine tool has a cover body with a window, the window including two spaced window plates defining an airtight space therebetween. The space is brought to a pressure other than atmospheric. An indicator is coupled to the cover body and has an indicator portion that is displaced in response to pressure in the space. The indicating portion is visually observable from outside the machine tool, so that the airtightness of the window may be determined by visually observing the position of the indicating portion.
