Abstract: Provided is a multi-joint bending structure body that makes it possible to obtain a structure capable of making a small-radius turn. The present invention comprises: a plurality of first bendable parts 9 and second bendable parts 11 that can elastically bend with respect to the axial direction; and an intermediate part 13 that is positioned between a first bendable part 9 and a second bendable part 11 which are adjacent to each other. The first bendable parts 9 and the second bendable parts 11 are provided with a flexible member 17 that is an integral body in the axial direction. The intermediate part 13 is attached to the flexible member 17 between the first bendable part 9 and the second bendable part 11 which are adjacent, and suppresses the bending of the flexible member 17 with respect to the axial direction.

Abstract: Forming a caulking portion involves forming: a planar portion that is connected to a main body of an iron core piece, that is formed into a concave shape with respect to a face of the iron core piece which is on one side in the thickness direction, that formed into a convex shape with respect to a face of the iron core piece which is on another side in the thickness direction, and that is parallel to the faces; and a pair of extended portions that include a pair of sloped portions which extend out obliquely from both ends, along the lengthwise direction of the caulking portion, of the planar portion, toward mutually opposite sides in the lengthwise direction and toward another side in the thickness direction. Forming the pair of sloped portions involves extending the pair of sloped portions in the oblique directions.
