Abstract

PURPOSE:To both improve the productivity of a coil and simplify its equipment, by constructing a pancake coil and press-forming it with a press device. CONSTITUTION:A pancake coil 12 is wound in such a manner that the coil thickness of the pancake coil 12 corresponding to the linear part of a saddle-shaped deflecting coil is the same as a thickness change of the saddle-shaped deflecting coil and a required coil length can be obtained by thinning the coil thickness of the pancake coil 12 corresponding to the front and rear bend part. Said pancake coil 12 is press-formed by a press device 13. Said press device 13 is constructed such that onto its press base 24 a front protrusive part 25, rear protrusive part 26 further left right retainers 27 are secured, and between said front and rear protrusive parts 25, 26 and left-right retainers 27 a press lower mold 28, movably urged upward always by a spring, is provided, and a press upper mold 31, vertically movable with a saddle- shaped concaved part 30 in its bottom face, and bend part holding plates 32, 33 are provided.
