とする高周波焼入れコイル体。 This is a coil body used for induction hardening of a valve shaft 10 for a rack-and-pinion type power steering of an automobile, and has a small hole 12a provided approximately in the center of the valve shaft 10 to allow oil to flow inside and outside the shaft. The coil parts 1b, 1l, 1f, and 1h whose current directions are opposite to each other in the small hole cylinder part 12 are provided to prevent the small hole cylinder part 12 from overheating, and to prevent the small hole cylinder part 12 from flowing in the axial direction. The hardened coil parts 1c, 1e and 1i, 1k of the upper part 11 and lower part 13 are surrounded in a substantially semicircular shape and connected and molded into a semi-open type, so that the valve shaft 10 can be hardened in one step. Features an induction hardened coil body.
