The present invention relates to a structurally novel eccentric cam action door closer for a glass door. The matching of the first and second rollers on the piston pressing assembly with the eccentric cam on the cam shaft realizes the door closer stably keeps the door in the opened or closed state. When the door is clockwise opened in place, the first roller is embedded in the first opening arc recess, thereby fixed to the eccentric cam. When the door is counterclockwise opened in place, the second roller is embedded in the second opening arc recess, thereby fixed to the eccentric cam. When the door is closed in place, the first and second rollers are embedded in the first and second closing arc recesses, thereby fixed to the eccentric cam. Thus, the cam shaft is stopped from rotating, achieving door angle fixing effect and stopping the door.
