PROBLEM TO BE SOLVED: To provide an automatic transmission, enabling a specific attenuation amount to be added, without changing oscillation property as far as possible. SOLUTION: Since a dynamic damper 39 given to a rotor of a clutch piston 32 or the like of a lock-up clutch 12 constituting the automatic transmission 10 has a rigid body 49 having an attenuation function and an inertia mass body 50, generation of judder in the automatic transmission 10 is suppressed, and the specific attenuation amount is given without changing the oscillation property of a whole automatic transmission 10 as far as possible.
