Claims

[Scope of Claim for Utility Model Registration] (1) The interior of a hermetically sealed container consisting of a cover and a case supported via bearings on a rotating shaft with a drive disk fixed to the tip thereof, and a cooling fan attached to the outer periphery. and a sealing device which is separated into an oil reservoir chamber and a torque transmission chamber in which the drive disk is housed by a partition plate having an oil outflow adjustment hole, and which faces the outer peripheral wall surface of the drive disk where oil collects during rotation. A dam is formed on a part of the inner circumferential wall of the casing, and a circulation path is formed in connection with the dam, which leads from the torque transmission chamber side to the oil sump chamber side. A temperature-sensitive element provided on the front surface of the cover is fixed to the temperature sensor, and a valve member that opens the outflow adjustment hole of the partition plate when the external ambient temperature exceeds the set value at the other end and closes it when the temperature falls below the set value. The drive side is provided internally so as to respond to deformation due to temperature changes, and increases or decreases the effective contact area of oil at the torque transmission gap provided on the wall facing the outside of the case and cover, which forms the drive disk. In a fan coupling device configured to control torque transmission from the rotating shaft body side to the driven side sealing case side, the outflow adjustment hole 5
A temperature-sensitive fluid type fan coupling device characterized in that a protrusion 14 having a flat bottom surface larger than the circumferential edge of the outflow adjustment hole 5' is provided on the side of the valve member 8 opposite to the outflow adjustment hole 5'. (2) A temperature-sensitive fluid type fan coupling device according to claim 1, wherein the protruding portion 14 is formed by pressing the valve member 8. (3) A temperature-sensitive fluid type fan coupling device according to claim 1, wherein the protruding portion (14) is constructed by fixing a separate plug body to the valve member (8). (4) A temperature-sensitive fluid type fan coupling device according to claim 1, characterized in that a sealing member 15 is attached to the bottom surface of the protrusion 14. (5) A temperature-sensitive fluid type fan coupling device according to claim 3, wherein the plug body is constituted by a sealing member 15.
