INDUCTION HEATING METHOD AND MANUFACTURING METHOD FOR RING-SHAPED MEMBER, RING-SHAPED MEMBER, BEARING, INDUCTION HEATING APPARATUS, MANUFACTURING METHOD FOR BEARING, MANUFACTURING METHOD FOR VEHICLE, AND MANUFACTURING METHOD FOR MECHANICAL DEVICE

Abstract: a ring-shaped member is induction-heated by supplying a current to an induction coil. an induction heating step includes induction-heating the ring-shaped member using an induction coil disposed at a radially inward position of the ring-shaped member in a state in which no substantial coil is disposed at a radially outward position of the ring-shaped member, or induction-heating the ring-shaped member using an induction coil disposed at the radially outward position of the ring-shaped member in a state in which no substantial coil is disposed at the radially inward position of the ring-shaped member. effective lengths of the induction coils are set to be larger than an axial length of the ring-shaped member.
