PROBLEM TO BE SOLVED: To provide a food grilling apparatus for conveying a food while keeping the distance between an infrared heater unit and the surface of the food constant so that a homogeneous bake can be formed even if the width of the food is varied.SOLUTION: The transportation face height of a transportation net belt (19) for running according to the rotation of a drive rotor (15) and a driven rotor (13) and extendible at least in the transportation direction while netting a wire for running in accordance with the rotation of the drive rotor (15) is changed in accordance with the thickness of the food (F) by transportation face changing means (53, 55) disposed on the upstream side of the transportation direction of heating means (25), thereby to make constant the distance between the heating means (25) and the upper face of the food (F).SELECTED DRAWING: Figure 5【課題】食品の厚さが異なる場合であっても、赤外線ヒータユニットと食品の表面の間隔が一定になるように搬送して均一な焼き目を形成することを可能にする食品炙り装置を提供する。【解決手段】駆動回転体（１５）及び従動回転体（１３）に掛渡され、線材を編み込んで少なくとも搬送方向へ伸長可能で、駆動回転体（１５）の回転に伴って走行する搬送網ベルト（１９）の搬送面高さを、加熱手段（２５）の搬送方向上手側に設けられた搬送面変更手段（５３、５５）により食品（Ｆ）の厚さに応じて変更し、加熱手段（２５）と食品（Ｆ）上面の間隔を一定にする。【選択図】図５
