Good appearance is maintained regardless of dimensional accuracy.

Further, in the embodiment described above, the engagement recesses 67 are formed as positioning engagement parts in both side pieces 65 of the grip part 57 of the waste tray 55, and the engagement recesses 67 are formed as positioning engagement parts.
An engagement protrusion 66 is located at the lower front side of the
However, an engaging protrusion is formed on the grip portion 57,
Engagement recesses may be formed in the main frames 12 and 13.

In addition, the projecting piece 59 of the tray portion 56 of the waste tray 55
The notch portion 6 formed in the side piece portion 65 of the grip portion 57
3, the engagement piece 60 of the plate part 56 engages with the lower surface of the attachment part 61, and the front edge of the plate part 56 does not rise.

[Effect of idea]

According to the present invention, the waste tray is located below the grill in the roasting chamber of the toaster main body, is disposed on the bottom plate so as to be movable back and forth in the front and rear directions, and is advanced forward through an opening at the bottom of the door body. consists of a metal plate plate part and a grip part molded from synthetic resin, and the plate part is provided with a fixing part protruding downward in a concave shape at the front part, and a roughly L-shaped part at the front part. An engaging piece is provided that protrudes forward from the lower end of the downwardly directed projecting piece, the grip part has an inwardly protruding attachment part, and the fixing part engages with the upper surface of this attachment part. At the same time, a notch portion for engaging the projecting piece is formed in the mounting portion in the front-rear direction, and the front portion of the dish portion is overlapped with the upper surface of the mounting portion of the grip portion to form the mounting recess. At the same time, the projecting piece is engaged with the inner end position of the notch of the mounting part, and the engaging piece is engaged with the lower surface of the mounting part, and the engaging piece is engaged with the mounting recess of the mounting part. Since the fixing part is caulked with rivets and the grip part is fixed to the tray part, the crumb tray inserted through the lower opening of the door of the roasting chamber of the toaster body is attached to the grip part molded from synthetic resin. The plate part is riveted and fixed to the inner mounting part, and the engaging piece protruding from the front part is engaged with the lower surface of the mounting part of the grip part, so that even if the dish part is deformed, the front part of the dish part will not float. It does not climb up, has a simple structure, can prevent deformation, and can be manufactured at low cost because the tray part of the waste tray can be press molded and the engaging piece can be molded at the same time.
