A lockup device1is disposed inside a fluid chamber between a front cover3and a turbine4and provided with a clutch-purpose friction plate12, a pair of drive the plates13and14, a driven plate15, and coil springs16. The friction plate12can be coupled with the front cover3. An extended part18extends from one of the plates13and14toward the other and engages with the inside circumferential edge of the friction plate12such that the friction plate cannot rotate but can move in the axial direction relative to the extended part. The driven plate15is fixed to the turbine4. The coil springs16are compressed between pair of drive the plates13and14and the driven plate15when the pair of drive plates and the driven plate rotate relative to each other.
