Claims

[Scope of Claim for Utility Model Registration] A sealed case consisting of a body and a cover supported for relative rotation on a rotary drive shaft with a drive disk fixed to the tip and a cooling fan etc. attached to the outer periphery, and the inside of this sealed case. a partition plate that divides the oil storage into an oil reservoir chamber and a torque transmission chamber and has an oil outflow adjustment hole, and a plate-shaped plate whose base end is fixed to the partition plate and whose free end touches and separates from the peripheral edge of the outflow adjustment hole. a valve member, a temperature sensing element made of bimetal disposed on the outside of the cover side of the sealed case, one end of which is in contact with the temperature sensing element, the other end of which extends through a shaft hole provided in the cover, and the other end of which is connected to the valve member; A temperature sensing body comprising a piston rod in contact with the member, and a weight fixed on the valve member and urging the free end of the valve member toward the outflow adjustment hole based on centrifugal force during rotation. In a temperature-sensitive fluid type fan coupling device in which a valve member opens and closes an outflow adjustment hole in conjunction with the bending deformation due to temperature changes, the plate-shaped valve member has a valve member located near the contact position with the piston rod from the free end of the plate-shaped valve member. 1. A temperature-sensitive fluid type coupling device, characterized in that the rigidity against bending of the distal end portion thereof is lower than the rigidity of the root portion extending from the vicinity of the contact position to the proximal end portion.
