Claim 3:
4. The damper device according to claim 1, wherein
when in an uncompressed free state, the length of the first elastic member is the same as the widths of the first support portion and the first accommodation portion in the circumferential directions of the first and second rotors, respectively, and when in an uncompressed free state, the length of the second elastic member is the same as the widths of the second support portion and the second accommodation portion in the circumferential directions of the first and second rotors, respectively,
the angular offset of the first accommodation portion relative to the first support portion causes 1) the first elastic member to transition from an initial compressed state thereof to its uncompressed free state and then to be recompressed as the first rotor rotates from the neutral condition in the first rotational direction with respect to the second rotor, and 2) the first elastic member to be further compressed from the initial compressed state thereof as the first rotor rotates from the neutral condition in the second rotational direction with respect to the second rotor, and
the angular offset of the second accommodation portion relative to the second support portion causes 1) the second elastic member to transition from an initial compressed state thereof to its uncompressed free state and then to be recompressed as the first rotor rotates from the neutral condition in the second rotational direction with respect to the second rotor, and 2) the second elastic member to be further compressed from the initial compressed state thereof as the first rotor rotates from the neutral condition in the second rotational direction with respect to the second rotor.
