摘要： PROBLEM TO BE SOLVED: To provide a torque converter capable of certainly establishing the centering of a lockup piston, its positioning in the axial direction, and sealing the gap between the lockup piston and a member supporting it while the number of component parts is decreased as much as practicable.
SOLUTION: The torque converter is structured so that a bushing 23 is press-fitted into an axial direction hole formed at the internal circumferential end 20a of the lockup piston 20. The bushing 23 has the centering function for the lockup piston 20, the positioning function for the lockup piston 20 in the axial direction, and the sealing function to seal the gap between the internal circumferential end 20a of the lockup piston 20 and a turbine hub 9. In this manner, one bushing 23 exerts three functions, which allows decreasing the number of component parts.
