    摘要: In order to provide an air core coil fitting apparatus that can automatically fit an air core coil onto a core, an air core coil fitting apparatus includes a holding member, a coil fitting rod, a rod driving member, a pushing member, and a sending member. The holding member holds a core main body that is formed in a ring shape, has a gap extending through the core main body from an inner circumferential face to an outer circumferential face thereof, and allows an air core coil wound in advance to be fitted onto the core main body from one end thereof. On the coil fitting rod, the air core coil that is to be fitted onto the core main body held by the holding member is fitted. The rod driving member brings a front end of the coil fitting rod close to or into contact with the one end of the core main body held by the holding member. The pushing member pushes the air core coil fitted on the coil fitting rod, toward the one end of the core main body. The sending member is disposed at a circumferential edge of the core main body held by the holding member, and pulls the air core coil pushed by the pushing member and fitted onto the core main body, toward another end of the core main body.
