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.

Abstract: An electronic device is provided. The electronic device includes a display extending from a first housing to a second housing, and a hinge structure rotatably connecting the first housing and the second housing and including a fixed member, a first rotary member coupled to the fixed member so as to be rotatable about a first axis extending parallel to an axial direction and connected with the first housing, a second rotary member coupled to the fixed member so as to be rotatable about a second axis parallel to the axial direction and connected with the second housing, a first guide member coupled to the first rotary member so as to be rotatable about a third axis parallel to the first axis, a second guide member coupled to the second rotary member so as to be rotatable about a fourth axis parallel to the second axis, a first rotary plate at least partially coupled to the first guide member to rotate about the third axis with the first guide member and supporting a partial area of the display, and a second rotary plate at least partially coupled to the second guide member to rotate about the fourth axis with the second guide member and supporting another partial area of the display. When the first housing or the second housing is folded or unfolded, the first rotary member rotates about the first axis in a first rotational direction, the first guide member and the first rotary plate rotate about the third axis in the first rotational direction, the second rotary member rotates about the second axis in a second rotational direction opposite to the first rotational direction, and the second guide member and the second rotary plate rotate about the fourth axis in the second rotational direction.
