PROBLEM TO BE SOLVED: To attain a stopper mechanism by a simple structure in a damper device with a widened torsional angle. SOLUTION: The damper device includes the first and second retaining plates 38, 39; an outer periphery-side torsion spring 44 supported by the retaining plates 38, 39; a pair of clutch plates 43; and an inner periphery-side torsion spring 45 supported by the clutch plates 43. The first and second retaining plates 38, 39 and the pair of clutch plates 43 include a stopper portion 65 at which both the plates are engaged with each other when they exceeds a predetermined relative rotating angle range.
