- the cam 20 is connected to a hinge shaft 90 coupled to the housing 10 so that when the hinge shaft 90 is rotated by the opening of the door 200, And is a member that rotates eccentrically as a starting point.
- a hole 22 for the hinge shaft 90 to pass therethrough is formed at the tip of the cam 20 and a coupling ring 24 is formed to protrude along the circumferential surface of the hole 22, 24 are fitted into a hole 12 formed at the front end of the housing 10 and the cam 20 is assembled to the front end of the housing 10.
- the cam 20 and the door 200 are connected to each other by the hinge shaft 90 by passing the hinge shaft 90 through the hole of the cam 20 assembled at the front end of the housing 10.
- the lower end of the cam 20 is bent in one direction and the roller 30 is brought into contact with the lower outer curved surface portion 26 of the bent cam 20.
- a locking pin 14 is coupled to the front end of the housing 10 and the closing operation of the door 200 is completed with the locking pin 14 and the inner surface of the cam 20 is hooked, So that the eccentric rotation does not occur anymore.
- the roller 30 moves backward in accordance with the eccentric rotation of the cam 20 in a state of being in contact with the outer curved surface portion 26 of the cam 20.
- the roller 30 is coupled to a bracket 42 formed on the front of the damper case 40 by a pin 44 and is inserted into the damper case 40 40 are pushed backward.
- the damper case 40 is a member that slides in the forward and backward directions in accordance with the eccentric rotation of the cam 20 while being accommodated in the space 11 of the housing 10.
