PROBLEM TO BE SOLVED: To provide a simple, compact size, and low-cost structure which can firmly form a rice ball with the surface thereof not being broken and the inside thereof being soft, and reproduce feeling and texture similar to vinegared rice shaped by hands.SOLUTION: A rice molding mechanism includes a folding molding form 11 that includes: a bottom mold 11b for rice body lower part molding that is located in a center a concave 11a for rice body one side part molding that is rotatably coupled to one side end of a bottom mold 11b through a hinge part 12 and the other side concave 11c for rice body other side part molding that is rotatably coupled to the other side end of a bottom mold 11b through a hinge part 13, and in which one side concave 11a and the other side concave 11c are respectively folded through hinge parts 12, 13 in an inside block direction through a bottom mold 11b, thereby a space part QS for rice molding that is surrounded by a bottom mold 11b, one side concave 11a, and the other side concave 11c respectively is made so that a formation sheet shape rice Q can be molded to vinegared rice Q1.COPYRIGHT: (C)2014,JPO&INPIT【課題】表面は型崩れせずにしっかりと、内部はふっくらと成形でき、手で握ったシャリ玉と同様の食感を再現できる簡易で小型且つ低コストの構成とする。【解決手段】中央に位置する米飯塊底部成形用の底型11bと、底型11bの一側端にヒンジ部12を介して回動可能に連繋された米飯塊一側部成形用の一側凹型11aと、底型11bの他側端にヒンジ部13を介して回動可能に連繋された米飯塊他側部成形用の他側凹型11cとを備え、底型11bを介して一側凹型11aおよび他側凹型11cそれぞれをヒンジ部12、13を介して内側閉塞方向に折り込むこと、底型11b、一側凹型11a、他側凹型11cそれぞれによって囲繞された米飯成形用空間部QSを形成シート状米飯Qをシャリ玉Q1に成形可能にした折り畳み成形型11を備える。【選択図】図5
