Provided is a highly reactive fluid fan coupling device utilizing the non-Newtonian fluid characteristics of oil, thereby obtaining an excellent reaction rate of fan rotation using a control signal. In the fan coupling device, where the interior of a sealed housing supported on a rotary shaft with a drive disk secured thereto is partitioned in an oil reservoir chamber and a torque transmission chamber placing the drive disk thereinto by a partition plate; drive torque is transmitted to a driven side by oil supplied to the torque transmission chamber; and opening and closing of a flow path of oil is controlled by a valve member actuated by an electromagnet, wherein a mechanism to scrape out the oil in the oil reservoir chamber utilizing the non-Newtonian fluid characteristics of oil is provided on the drive disk so as to be opposed to an oil supply adjusting hole of the partition plate.
