Abstract
A lockup clutch of a fluid type torque converter apparatus is disposed in parallel to a fluid type torque converter and directly connects an input shaft and an output shaft to each other. The lockup clutch comprises first and second disc elements disposed midway of a drive force transmission line in an axially spaced relation and an opposing relation to each other, and connected to each other by fastening members in a manner that the relative rotation of one disc element to another is impeded; a third disc element disposed between the first and second disc elements and rotatable relative to the first and second disc elements; compression coil springs adapted to act as shock absorbers when the first and second disc elements are rotated relative to the third disc element; slots of a predetermined length running in the third disc in the circumferential direction thereof and receiving therein the fastening members, respectively; and spacers formed independently of the fastening members and fitted on the intermediate outer peripheral portions of the fastening members, which intermediate portions are inserted in the slots, respectively.
