PURPOSE: A track structure of an arm for opening and closing a window, which can reduce damage to a window by securely fixing a lever chain tension part, is provided to improve reliability by inducing the stable operation of a lever chain tension part. CONSTITUTION: A track structure of an arm for opening and closing a window comprises a magnetic track main body and a bending part. The magnetic track main body has a space. The space is formed by bending the outer circumference of the magnetic track main body toward the inside of the space. The space is composed of a groove. The bending part induces the connection of a load bar(32) along the grooves of the space. |
