Abstract:
The present invention relates to a door closer that has high usability and can reduce construction costs. A door closer according to an embodiment of the present invention may comprise a first closer part and a second closer part. The first closer part is coupled to a door frame and a door, and provides a rotation force in a direction in which the door is closed. Further, when the door is rotated by the first closer in a direction in which the door is closed, the second closer part reduces the rotation speed of the door by a damping force of a viscous fluid contained therein.
