Claims

[Scope of utility model registration request]

The inside of the sealed container is made up of a case and a cover, which is supported via a bearing on a rotating shaft body with a drive disk fixed to its tip, and a cooling fan member is attached to the outer periphery. An oil reservoir chamber and a torque transmission chamber containing the drive disk are separated by a plate, and an inner peripheral wall surface on the sealing case side facing the outer peripheral wall of the drive disk where oil collects during rotation is divided by a plate. forming a dam in part and a circulation path leading from the torque transmission chamber side to the oil reservoir chamber side connected to the dam, and opening the outflow adjustment hole of the partition plate when the external ambient temperature exceeds a set value; A valve member that closes when the temperature is below a set value is provided internally in response to changes in the temperature of the temperature sensing element, and effective oil contact is made in the torque transmission gap formed on the opposing wall surface between the drive disk and the case and cover. In a fan coupling device that controls the transmission of rotational torque from the rotating shaft body on the driving side to the sealing case side on the driven side by increasing or decreasing the area, the side wall surface of the outer peripheral end of the drive disk is bent to form an L-shaped cross section. is formed into an annular protruding wall having a shape or a T-shape, and an oil escape hole communicating with the circulation path through the dam is provided in the protruding wall portion;
Further, the width of the dam is set to correspond to the entire width of the protruding wall on the drive disk side, and furthermore, oil is communicated with the drive disk to the front and rear torque transmission gaps on the inside of the protruding wall near the relief hole. Along with drilling a hole,
A temperature-sensitive fluid type fan coupling device characterized in that at least one dam member is provided near the bent base of the protruding wall and at a position before the relief hole in the rotational direction.
