ABSTRACT:
A vacuum drier apparatus capable of preventing the thermal deformation of the protection member as well as scattering of the tempered glass plate in a case of an accidental breaking of the tempered glass plate. The apparatus includes elastic supporter members located between the glass plate and the protection member, for supporting the glass plate and the protection member with respect to each other, such that the glass plate can be pressed tightly to seal off the opening section of the vacuum drying space, while the protection member can be pushed away from an edge of the front side of the opening window by an external pressure exerting on the protection member. The protection member is preferably a transparent plastic plate in an outwardly curving dome-shaped form.
