PURPOSE: A clutch for an automatic transmission is provided to improve durability despite the rotation of a clutch plate and a clutch disk by preventing the slippage of a reaction plate and a snap ring via a slip preventing unit. CONSTITUTION: A clutch for an automatic transmission includes a clutch plate, a clutch disk, a reaction plate(5), a snap ring(7), and a slip preventing unit. The clutch plates are fixed on the spline of an outer hub. The clutch disks are formed between the clutch plates. The clutch disks move axially by the mutual action of the hydraulic pressure of oil and the elasticity of a return spring. The reaction plate is combined to the outer hub when the clutch disks move axially. The slip preventing unit connects the reaction plate with the snap ring by using a protrusion(13) of the reaction plate and a protrusion hole(15) of the snap ring. Since the reaction plate is combined with the snap ring, the slippage between the reaction plate and the snap ring is avoided.
