The invention relates to a double damping flywheel for a clutch, comprising primary and secondary coaxial members. The members are mobile in rotation in relation to one another and coupled by first and second damping elements arranged in series by a connecting web. The first damping element includes at least one curved elastic member running circumferentially between two first seatings carried by the connecting web; the second damping element includes at least two groups of elastic members, each including at least two straight elastic members arranged in series by an intermediate bearing element, each group of straight elastic members running circumferentially between two second seatings carried by the connecting web; one annular member for phasing the straight elastic members, separate from the connecting web, carrying the intermediate bearing element of each group; wherein, the maximum angular displacement between the primary member and the connecting web, and the maximum angular displacement between the secondary member and the connecting web, is less than 30°, preferably less than 10°.
