Claims

[Scope of utility model registration request]

It includes a rod-shaped governor body having a shaft hole in the longitudinal direction, a governor valve inserted into the shaft hole of the governor body, and a governor adapter fitted into the outer periphery of one end of the governor body,
A first land, a first seal ring, a second seal ring, and a third seal ring that are in close contact with the inner circumferential surface of the governor adapter are formed on the governor body in order from the end thereof, and the first seal ring and the second seal ring are formed on the governor body. There is also a line pressure oil passage supplied through the governor adapter between the
A governor pressure oil passage is provided between the seal ring and the third seal ring for converting line pressure oil into governor pressure oil and sending it out to the outside of the governor adapter. A governor device for a hydraulic automatic transmission for a vehicle in which a part is rotatably attached to a transaxle case via a governor adapter and is driven by a governor drive shaft, the governor device having a governor pressure fluid connected to the third seal ring. A governor device for a hydraulic automatic transmission for a vehicle, characterized in that a second land having an outer diameter substantially equal to the outer diameter of the first land is provided on the outer periphery of the governor body on the side opposite to the passage.
