Abstract: According to an embodiment of the disclosure, an electronic device may comprise a first housing, a second housing, a hinge structure, and/or a flexible display. The hinge structure may be rotatably connect the second housing to the first housing. The flexible display may be at least partially bendable in response to the rotation of the second housing relative to the first housing. The hinge structure may include at least one rotating member, at least one detent member, and/or at least one pin member. The rotating member may include a first detent member coupled to the first housing and rotatable about a first rotational axis and/or a second detent member coupled to the second housing and rotatable about a second rotational axis parallel to the first rotational axis. The detent member may include a first detent member disposed in the first rotating member and including a first detent slot and/or a second detent member disposed in the second rotating member and including a second detent slot.

Abstract: According to an embodiment of the disclosure, a foldable electronic device may comprise a hinge structure unit including a first hinge structure and a second hinge structure and a bracket to which the hinge structure unit is rotatably coupled. The first hinge structure or the second hinge structure may include a rotator provided with an interlocking hole and a cam having an end provided with an interlocking protrusion to be fitted into the interlocking hole to be assembled to the rotator.

Abstract: An electronic device includes a display, a first housing, a second housing and a hinge assembly configured to connect the first housing and the second housing, and having a pair of hinge axes. The hinge assembly includes a hinge bracket including an intermediate protrusion formed to protrude in a direction of a middle axis perpendicular to the pair of hinge axes, a pair of hinge structures connected to the hinge bracket to be rotatable about the pair of hinge axes, and an intermediate member including a through-hole into which the intermediate protrusion is inserted, to be rotatable about the middle axis with respect to the hinge bracket. The intermediate protrusion also includes a protrusion base having a first radius, and a head including a projection which is formed on the protrusion base and which has a second radius greater than the first radius.
