INSULATING STRUCTURE FOR ROTARY ELECTRIC MACHINE AND METHOD FOR PRODUCING INSULATING STRUCTURE FOR ROTARY ELECTRIC MACHINE

This insulating structure is for a rotary electric machine that is provided with a layered core (5) obtained by layering steel sheets and in which a resin insulating section (6) is formed so as to cover at least a surface section of a part around which a coil (4) is wound in the layered core (5). The resin insulating section (6) is provided with a bulge section (6d) that becomes thicker in a circumferential direction (R) toward the center than on both end surfaces along the axial direction (X) of the layered core (5). 一种旋转电机的绝缘结构体，所述绝缘结构体具备将钢板层叠而成的层叠铁心(5)，并且在该层叠铁心(5)至少将卷装线圈(4)的部位的表面部覆盖地形成树脂绝缘部(6)，树脂绝缘部(6)具备鼓出部(6d)，所述鼓出部(6d)沿层叠铁心(5)的轴向(X)在中央侧朝向周向(R)形成为比两端面厚的壁厚。
