PURPOSE: A chamber having a grind preventing structure is provided to induce higher electricity generating efficiency by lowering an average driving temperature of a photovoltaic generation module because of an improved cooling effect. CONSTITUTION: A chamber body(51) has a structure whose top is opened. A chamber lid, coupled to an upper part of the chamber body, opens or closes the chamber. A sealing member, arranged on a coupling face between the chamber body and the chamber lid, performs a sealing function. The height of an outer coupled face in the chamber body is lower than that of an inner coupled face. When the chamber lid is coupled to the chamber body, the contact part between the inner coupled face and the chamber lid can be minimized.
