Abstract
The disclosure discloses a foldable electronic device including rotary supports connected to housings, arm parts connected to the rotary supports, and rotary shafts disposed in the arm parts. At least one arm part among the arm parts includes arm cam structures in which fastening holes spaced apart from each other by a predetermined gap are formed. A shape of a cross-section of a rotary shaft inserted into the fastening holes includes flat areas and curved areas when viewed in an axial direction in which the rotary shaft is inserted. The rotary shaft is formed such that a first thickness of a first portion at least partially disposed in one fastening hole among the fastening holes differs from a second thickness of a second portion at least partially disposed in another fastening hole among the fastening holes.
