  "abstract": "An example hinge structure of an electronic device includes a first rotation part connected to a first housing and being rotatable about a first axis, a second rotation part connected to a second housing and being rotatable about a second axis in an opposite direction to that of the first rotation part, a first arm part connected to the first rotation part and being rotatable about a first rotary shaft, a second arm part connected to the second rotation part and being rotatable about a second rotary shaft in an opposite direction to that of the first arm part, a first fixing pin connecting the first rotation part and the first arm part, and a second fixing pin connecting the second rotation part and the second arm part. The first rotation part may include a first bracket body, and a first sliding part formed on one side of the first bracket body, and including a first slide hole, into which a portion of the first fixing pin is insertable, the first arm part may include a basic body, and a first connection part formed on one side of the first basic body, and the first connection part may include a first connection hole, into which a portion of the first fixing pin is insertable, and a first protrusion formed at a peripheral portion of the first connection hole such that at least a portion thereof is located in the first slide hole to contact the first sliding part.",
