A mounting rack (14) partitions the bottom portion of the heating chamber (12) from an upper portion thereof, and supports an object to be heated. The mounting rack (14) has engaging portions (28) engaged with a lower edge (27) of the opening (20) of the heating chamber (12), by means of which the mounting rack (14) can pivot about the engaging portions (28) and be detached from the lower edge (27), and also has recesses respectively formed on lower surfaces of the edges (22) opposite to wall surfaces, except for the opening (20). A sealing member (29) seals gaps between the wall surfaces of the heating chamber (12), except for the opening (20), and the opposite edges (22) of the mounting rack (14), and has a projection fitted in a corresponding one of the recesses of the mounting rack (14), a base portion formed integral with the projection and brought into tight contact with each opposite edge of the mounting rack (14), and a tongue formed integral with the base portion and urged against a corresponding one of the wall surfaces of the heating chamber (12), except for the opening (20).</p> |
