。 A hydraulic chamber defined by a clutch drum and a clutch piston, a communication hole provided in the piston that communicates with the outside of the hydraulic chamber, and a communication hole that is shut off when hydraulic pressure is applied to turn the clutch ON and turn the clutch OFF. Therefore, in a clutch device for an automatic transmission equipped with a drift-on ball that connects the communication hole when discharging hydraulic pressure, even when the drift-on ball is in a position where it blocks the communication hole, there is a hole in the communication hole to turn the clutch ON. A clutch device for an automatic transmission, characterized in that a clutch device for an automatic transmission is formed with an auxiliary passage that communicates with the clutch slightly to the extent that it hardly affects the hydraulic action of the clutch.
