A washer having such a thickness t that a value (L3−(L1+L2+t)) obtained by subtracting the sum of a first distance L1 in an axial direction between a leading end face of a friction member and a face of a lockup piston, a second distance L2 in the axial direction between a shell-side abutting face of a pump shell and a face of an outside extended portion of an output hub, and the thickness t in the axial direction of the washer, from a third distance L3 in the axial direction between an opposed face of a front cover and a cover-side abutting face of a tubular portion, is in a predetermined range larger than zero, is selected and placed between the lockup piston and the outside extended portion of the output hub.
