The present invention relates to a heat-sensitive variable pulley and, in particular, to a heat-sensitive variable pulley capable of maintaining the rotational speed to be lower than a predetermined level using frictional heat due to slips. The heat-sensitive variable pulley of the present invention comprises a disk-shaped operation rotating part to rotate with one side joined to an operation motor and the other side formed with a first contact surface; a vertical rotation part to rotate with the outer circumference joined to a belt while a second contact surface on one side comes in contact with the first contact surface; and a contact variable part to adjust adhesion between the first and second contact surfaces using frictional heat due to slips between the first and second contact surfaces caused by rotational speed differences between the operation rotating part and the vertical rotation part. |
