Each of the right frame portion 41, the left frame portion 42, the front frame portion 43, and the rear frame portion 44 has a substantially L-shaped cross section orthogonal to the longitudinal direction.

  The right frame portion 41 and the left frame portion 42 are bent at substantially right angles along the inner surface of the second movable rail 32 while covering the upper surfaces of the pair of second movable rails 32. The right frame portion 41 is pivotally supported by one end portion of a connecting arm 53 (to be described later) of the door interlocking mechanism 50 on one end portion outside the portion covering the upper surface of the front frame portion 43 and on the front side of the grill box 45. An abutting portion 36 for abutting on the roller 55 and biasing to the back side of the grill 45 is provided.

  Further, the outer side surface of the front frame portion 43 at the center in the left-right direction is engaged with a later-described locking spring 90 (see FIGS. 16 and 17) provided on the back surface of the handle member 16. A locking member 120 (see FIGS. 3 and 16) formed in a U-shape projecting forward is fixed by a plurality of fixing screws 106 (see FIG. 16). Further, positioning pieces 131 and 132 (see FIG. 3) projecting upward are provided on the upper portions of both sides of the locking member 120 in the width direction. These positioning pieces 131 and 132 are inserted into insertion holes 141 and 142 (described later) formed in a connecting member 70 (described later) of the tray 60.

  The bottom of the tray 60 is fitted to the inside of the holding frame 40 having such a configuration, and the left and right edges of the tray 60 are placed on the right frame 41 and the left frame 42. The tray 60 is held by the holding frame 40.

  Thus, since the tray 60 is slid and moved by the rail mechanism 30 while being held by the holding frame 40, the tray 60 does not come into contact with the grill 45. Therefore, the tray 60 can be smoothly put in and out of the grill 45. Further, since the friction sound generated by rubbing the tray 60 against the grill 45 is not generated, the loading and unloading of the tray 60 can be silenced. In addition, since the tray 60 moves along the fixed rail 31 via the first and second movable rails 32 and 33, the slide path in the grill 45 is determined. As a result, the tray 60 does not rattle in the grill 45 and no sliding operation occurs, so that the tray 60 can be inserted and removed smoothly and stably.

  Next, the opening / closing structure of the door 15 will be described with reference to FIG. FIG. 6 is a perspective view of the open / close door 15 that is pivotally supported by the spindle 48. The open / close door 15 includes a rectangular main body frame 95. A glass window 96 that is a rectangular opening is formed in the approximate center of the main body frame 95. Side-view L-shaped support portions 97 and 98 that extend substantially at right angles to the back surface of the main body frame 95 are provided at both left and right ends of the main body frame 95. In these support portions 97 and 98, a support shaft insertion hole 99 through which the support shaft 48 is inserted is provided at each upper portion in a state in which the open / close door 15 is erected in the vertical direction. Under each of the support shaft insertion holes 99, connection holes 100 for rotatably supporting one end of a connection arm 53 described later are provided. A single glass plate 110 is fixed to the main body frame 95 so as to cover the glass window portion 96 from the back side.

  In the open / close door 15 having such a configuration, the support shaft 48 is inserted into the pair of support shaft insertion holes 99 and 99 of the support portions 97 and 98. And the longitudinal direction center part of the spindle 48 is fixed to the upper end part of the opening end which forms the opening part 8 of the grill warehouse 45, and the longitudinal direction both ends of the spindle 48 form the opening 12 of the housing | casing 2. Fixed to each inner surface. Thereby, the open / close door 15 rotates independently with respect to the support shaft 48.

A loop-shaped fixing portion 58 a formed at one end of the torque spring 58 is fixed to the inner surfaces of the support portions 97 and 98 of the main body frame 59. On the other hand, the other end of the torque spring 58 is fixed to the support shaft 48. Then, the other end portion of the torque spring 58 is fixed to the support shaft 48 in a state where the fixing portion 58a is substantially horizontal. That is, the state in which the open / close door 15 is open is a state in which no torque is applied to the torque spring 58. Therefore, even if the opening / closing door 15 is rotated by its own weight, the open state of the opening / closing door 15 is maintained by the biasing force of the torque spring 58. The torque is applied to the torque spring 58 by closing the door 15. The torque spring 58 shown in FIG. 6 corresponds to the “biasing means” of the present invention.

  Next, the structure of the door interlocking mechanism 50 will be described.
