PURPOSE: A motor pulley structure is provided to improve the assembling workability by employing a stopper limiting an installing position of a motor pulley. CONSTITUTION: A pulley hub(62) is provided with an axis hole(64) on which a motor axis(54) is installed. A stopper(66) is provided on an upper end of the axis hole(64) to limit an upper position of the motor axis(54). A belt groove unit(68) is formed on the pulley hub(62) as one unit. A belt for transferring a rotatory force to the motor axis(54) is rounded on the belt groove unit(68). An air hole for discharging air within the axis hole(64) is punched, when the motor axis(54) is inserted into the axis hole(64). A lower portion of the belt groove unit(68) is provided with a fan for forming an air stream in order to radiate heat of a motor.
