Abstract

PURPOSE:To improve the efficiency of winding operations for windings by forming a bobbin into a structure with end insulators and oil ducts annexed monolithically thereto. CONSTITUTION:The long side part 12 of a rectangular bobbin 11 is formed of a flat board made of a press board, while the short side part 13 thereof is a molded resin board made of fiber-reinforced plastic (FRP) which is formed to be nearly rectangular (concavo-convex) in the direction of the axis of the bobbin. Both upper and lower ends of a plurality of convex parts 13a projected outside the short side part 13 are further projected to form projections, which are made to be end insulators 13c located along the peripheral edges of both upper and lower ends of the short side part 13. Furthermore, in the inside peripheries at four corners of the short side part 13 are provided cut grooves 14 into which the ends of the long side part are inserted. That is, the bobbin is constituted in such a manner that nearly rectangular-wave-shaped short side part 13 and the end insulators 13c are annexed monolithically thereto.
