Beschreibung
Zusammenfassung:	A fitting structure and a coupling member including the fitting structure are provided. The fitting structure includes: a first section (100) including a shaft portion (110) and a diameter-enlarged portion (120) provided at one end of the shaft portion (110); and a second section (200) enclosing the first section (100) from the outside in a radial direction of the shaft portion (110). A diameter of the diameter-enlarged portion (120) is larger than a diameter of the shaft portion (110). The shaft portion (110) includes a recess (113) recessed inward in the radial direction of the shaft portion (110). The second section (200) extends in the radial direction of the shaft portion (110) and is elastically deformable at least in the radial direction of the shaft portion (110). The second section (200) includes a protrusion (210a, 210b) corresponding to the recess (113). The protrusion (210a, 210b) engages with the recess (113).
