Electronic device including fastening member

An electronic device comprising:

• a housing comprising a front cover and a rear cover fastened to the front cover;
• a first fastening structure arranged inside the housing;
• and
• a second fastening structure arranged inside the rear cover to be fastened to the first fastening structure,
• wherein the first fastening structure comprises:
• a fixing member fixedly arranged inside the housing;
• a rotation hook rotatably connected to the fixing member and configured to fasten to the second fastening structure;
• and
• an elastic member having a first end connected to the fixing member and a second end connected to the rotation hook, and
• wherein the elastic member generates a torque that rotates the rotation hook relative to the fixing member in a first direction and a second direction, a direction in which the torque is generated being based on a fastening state of the second fastening structure and the rotation hook.

An electronic device comprising:

• a first housing comprising a front cover and a rear cover configured to fasten to the front cover;
• a second housing connected to a display and rotatably connected to the first housing;
• a printed circuit board (PCB) arranged inside the first housing;
• a first fastening structure arranged in the PCB;
• and
• a second fastening structure arranged inside the rear cover to be fastened to the first fastening structure,
• wherein the first fastening structure comprises:
• a fixing member fixedly connected to the PCB;
• a rotation hook rotatably connected to the fixing member and configured to fasten to the second fastening structure;
• and
• an elastic member comprising a first end connected to the fixing member and a second end connected to the rotation hook and configured to generate a torque that rotates the rotation hook in a first direction and a second direction relative to the fixing member, a direction in which the torque is generated being based on fastening state of the second fastening structure to the rotation hook,
• wherein, before the second fastening structure is fastened to the rotation hook, the elastic member generates a torque in a direction in which the rotation hook presses a stopper comprised in the fixing member, and
• when the second fastening structure is fastened to the rotation hook, the elastic member generates a torque in a direction in which a fastening force between the second fastening structure and the rotation hook increases.
