[0007] As a conventional configuration in which the grill is moved in the front-rear direction in the cooking chamber in conjunction with the opening / closing door, for example, an engagement hole is formed at the tip of a connecting rod. A structure in which an engagement shaft is provided on both sides of the rear end portion of the grill in the engagement hole so as to pass through guide holes provided on both side walls of the cooking chamber, and the engagement shaft is inserted into the engagement hole. However, in the case of such a configuration, similarly to the above-described conventional one, the grill and the connecting rod cannot be removed, so that there is a problem that it is difficult to clean the cooking chamber. Since it is necessary and an arrangement space for disposing the connecting rod is required, the size becomes large, and a through hole for penetrating the connecting rod must be formed on both sides of the cooking chamber of the main body. The configuration is complicated.

As another conventional structure, a slit-shaped guide hole is provided on both side walls of the cooking chamber, and a slide member slidably attached to the guide hole is provided. A connection in which a protruding engagement shaft is provided, a locking member is provided inside the opening / closing door, that is, on the cooking chamber side, and an engagement portion having the same configuration as that described above is formed at the rear end of the grill. A member is provided, and the engaging shaft is engaged with the engaging hole of the connecting member, and the tip of the grill is formed on the opening / closing door to be locked by the locking member. In some cases, the grille locked by the locking member is moved in the front-rear direction. However, in the case of such a configuration, it is necessary to provide a connecting member having a complicated structure in the grill, and a pair of sliding members is required although a connecting rod is not required. Since the net and the connecting rod cannot be removed, there is a problem that it is difficult to clean the cooking chamber.
