Claims

[Scope of utility model registration request]

an input member that is driven by an engine and locks the rotor; a housing that is rotatable with respect to the input member via a bearing; a first storage chamber that is disposed within the housing and stores fluid in the housing; and the rotor. a partition plate that divides the rotor into a working chamber that accommodates the working chamber, a pump mechanism that sends liquid from the working chamber to the first storage chamber, and a torque that is formed between the opposite side of the rotor to the partition plate and the inner surface of the housing that is in contact therewith. transmission surface,
A slot provided in the partition plate and communicating the first storage chamber and the working chamber, a valve material for opening and closing the slot, a temperature sensitive member that rotates in response to temperature, and a base of the temperature sensitive member and the valve material. In the viscous fluid coupling device, the viscous fluid coupling device includes a rod, which is connected to both ends of the rod and rotates the valve member to open the slot by rotation of the temperature sensitive member, the rod being provided in the rotor and storing the viscous fluid. a second storage chamber, a flow path communicating from the outer circumference of the rotor to the second storage chamber, and a spring member having one end fixed to the rotor and a protrusion attached to the other end, the spring member being fixed to the rotor in accordance with rotation of the rotor. The viscous fluid coupling device is characterized in that the protrusion expands and contracts, and when the rotor rotates at high speed, the protrusion moves near the opening of the flow path.
