1. An electronic device comprising:
a first housing including a first surface;
a second housing including a second surface;
a third housing including a third surface;
a first hinge rotatably connecting the first housing and a first side surface of the second housing facing a first side surface of the first housing;
a second hinge rotatably connecting the first housing and a side surface of the third housing facing a second side surface of the first housing opposite to the first side surface of the first housing;
a flexible display disposed on the first surface, the second surface and the third surface;
a first magnet disposed in the second housing; and
a hinge lock which, in an abnormal state of the electronic device in which a portion of the first surface is adjacent to the second surface, faces the first magnet and which includes a pin insertable into a groove formed in at least one shaft in the second hinge,
wherein the first hinge and the second hinge are configured to provide an unfolded state in which the first surface, the second surface, and the third surface face the same direction or a folded state in which at least one of the first surface, the second surface, or the third surface face different directions, and
wherein the hinge lock is configured such that the pin is inserted into the groove by a force of the first magnet in the abnormal state of the electronic device, and the pin is disengaged from the groove as the electronic device changes from the abnormal state to the unfolded state.
