PURPOSE: A stopper system for a door is provided to facilitate the operation of a stopper through a switch by using the power transmission structure of the switch, a solenoid cylinder, and a link member. CONSTITUTION: A stopper system for a door comprises an electric input unit, a solenoid cylinder (20), a link member (30), and a stopper unit (40). The electric input unit includes an electrical switch (11). The electric input unit is installed on one side of a door (D) and generates an operation signal with the input of a user. The solenoid cylinder is electrically connected to the electrical switch and is operated by controlling the operation signal. The link member is combined with the rod of the solenoid cylinder and is elevated with the operation of the solenoid cylinder. The stopper unit is joined to one side of a link member and is rotated with the elevation of the link member to come in touch or untouched with the ground.
