PURPOSE: A safety device of a fan using a one-touch sensor is provided to save installation and maintenance costs and to be safely and efficiently used without using an ultra violet light sensor. CONSTITUTION: Human's skin contacts a safety net of a fan. The contact is inputted in a one-touch switch sensor so that the power of a fan is immediately blocked. The fan is rapidly stopped by operating a fastening brake. Herein, the fastening brake has a structure similar to one used in a dehydration tub of a washing machine. Accordingly, the reliability of the fan is improved.
