SHEET

PROBLEM TO BE SOLVED: To provide a sheet which fixes a magnet to a slot of a rotor core with good accuracy.SOLUTION: Sheets (1 and 2) respectively have two of long side portions (1a, 1b, and 2a, 2b) respectively wrapping long side opposite surfaces (3a and 3b) of a magnet (3); front portions (1c and 2c) which are formed between the two long side portions (1a, 1b, and 2a, 2b), and wraps a front side surface (3c); and two of short side portions (1d, 1e, and 2d, 2e) wrapping the short side opposite surfaces (3d and 3e). The two of short side portions (1d, 1e, and 2d, 2e) are formed so as to extend from the long side portions (1a, 1b, and 2a, 2b). The length of the short side portions (1d, 1e, and 2d, 2e) from the long side portions (1a, 1b, and 2a, 2b) is gradually increased in an opposite direction to an insertion direction in which the magnet (3) is inserted in a slot (5a).SELECTED DRAWING: Figure 1 【課題】磁石をロータコアのスロットに良好な精度で固定するシートの提供。【解決手段】シート（１、２）は、磁石（３）の長辺対向面（３ａ、３ｂ）をそれぞれ包む２つの長辺部（１ａ、１ｂ、２ａ、２ｂ）と、２つの長辺部（１ａ、１ｂ、２ａ、２ｂ）の間に形成されており、前方面（３ｃ）を包む前方部（１ｃ、２ｃ）と、短辺対向面（３ｄ、３ｅ）を包むそれぞれ２つの短辺部（１ｄ、１ｅ、２ｄ、２ｅ）とを有する。２つの短辺部（１ｄ、１ｅ、２ｄ、２ｅ）は、長辺部（１ａ、１ｂ、２ａ、２ｂ）から延びるように形成されている。短辺部（１ｄ、１ｅ、２ｄ、２ｅ）の長辺部（１ａ、１ｂ、２ａ、２ｂ）からの長さは、磁石（３）がスロット（５ａ）へ挿入する挿入方向と反対方向に向かうにつれて長くなる。【選択図】図１
