Hinge module and electronic device comprising same

An electronic device comprising:

• a first housing;
• a second housing configured to pivot between a first position at which the second housing is folded to face the first housing and a second position at which the second housing is unfolded at a specified angle from the first housing;
• a display including a first area disposed on the first housing, a second area disposed on the second housing, and a folding area disposed between the first area and the second area;
• and
• at least one hinge module disposed between the first housing and the second housing and pivotably connecting the first housing and the second housing to each other,
• wherein the hinge module comprises:
• a hinge bracket;
• a first rotation member coupled with the first housing and disposed on the hinge bracket pivotably or rotatably around a first folding axis;
• a second rotation member coupled with the second housing and disposed on the hinge bracket pivotably or rotatably around a second folding axis;
• a cam member disposed on the hinge bracket, facing at least part of the first rotation member and the second rotation member;
• and
• an elastic member configured to provide an elastic force to the cam member in a first action direction, and
• wherein, when the cam member receives the elastic force provided by the elastic member, the cam member is configured to at least partially contact an inclined surface of the first rotation member or an inclined surface of the second rotation member.
