A refrigerator includes a first tray assembly to define one portion of an ice making cell, a second tray assembly to define another portion of the ice making cell, a heater disposed adjacent to at least one of the first or second tray assemblies, and a controller configured to control the heater. The refrigerator further includes a pusher including a first edge having a surface pressing the ice or at least one of the first and second tray assemblies to easily separate the ice from the tray assemblies, a bar extending from the first edge, and a second edge disposed at the end of the bar; and a pusher link having a connection part connected to the pusher. The controller controls at least one of the pusher or the second tray assembly to move and to change a relative position between the pusher and the second tray assembly.
