Abstract: A safety device of two-way braking for a retractable door leaf is especially applied to a retractable door which can be retracted and released vertically or horizontally. By using a triggering device installed, a signal can be transmitted to a host of the door to cope with an external condition, and in turn to command a working status of a motor, during a process of closing or opening the door. The invention is primarily composed of a door, and at least two two-way triggering devices located at a closing side of the door leaf. The triggering devices are acted by a guarding plate located at the closing side, and are subjected to a touch piece located at the door in the other way. A command can be generated for providing to a host by the aforementioned two-way activation, thereby controlling a working status of a motor.
