Claims

[Scope of utility model registration request]

An induction hardening coil for a recess groove that moves in the longitudinal direction of the recess groove to induction surface harden the side portion between the top and bottom of the recess groove and the bottom, the coil being a left coil connected in series. , a connecting coil, and a right coil, and the left coil includes a left bottom coil located near the bottom of the recess groove and parallel to the longitudinal direction of the recess groove, and one end of which is connected to one end of the left bottom coil. an upper left coil connected to the bottom left coil and protruding from the top of the recess groove in a direction perpendicular to the left bottom coil and corresponding to the shape of the side of the recess groove; and at the other end of the upper left coil. A left power feeding section coil is connected at one end and is formed to protrude in a direction perpendicular to the longitudinal direction of the recess groove, and a lower left coil is connected at one end to the other end of the left bottom coil and is formed to face the upper left coil. and a left side coil having one end connected to the other end of the left lower coil and protruding toward the left upper coil in the longitudinal direction of the recess groove, and the right coil: a right bottom coil disposed close to and facing the left bottom coil; and a right top coil having one end connected to one end of the right bottom coil and facing the left top coil. a lower right coil having one end connected to the other end of the right bottom coil and facing the left lower coil; and a left side coil having one end connected to the other end of the right bottom coil. a right side coil formed to face each other, and a right power supply coil formed at the other end of the right side coil to protrude in a direction perpendicular to the longitudinal direction of the recessed groove, and the other end of the left side coil. and the other end of the upper right coil are connected by the connection coil, an induction hardening coil for a recessed groove.
