A torsional vibration dampening device 14 in a torque converter for dampening torsional vibration of torque transmitted from a piston to a driven plate includes an arc-shaped fluid chamber 26, a slider element 33, a seal element 30a and a choke C. The arc-shaped fluid chamber 26 is coupled to the piston and has an opening extending in circular directions. The slider element 33 sections the arc-shaped fluid chamber 26 in circular directions, are relatively movable in circular directions within the arc-shaped fluid chamber 26, and has a groove 30d corresponding to the opening. The seal element 30a is placed within the arc-shaped fluid chamber 26 and rotates along with the slider element 33 in unity to seal the opening. Fluid in the arc-shaped fluid chamber 26 pass the choke in accordance with the relative movement of the slider element 33.
