Abstract:
A damper mechanism comprising:a first rotary member; a second rotary member being configured to rotate relative to said first rotary member; a damper section being configured to couple elastically said first rotary member and said second rotary member together in a rotational direction, said damper section including an intermediate rotary member being configured to rotate relatively to said first and second rotary members, said intermediate rotary member having a gourd-shaped hole including, first hole, a second hole being configured to overlap with said first hole, and said first hole having a diameter larger than said second hole, and. a protruding section being an intersection of said first and second holes; a friction mechanism being configured to generate friction when said first rotary member and said second rotary member rotate relative to each other, said friction mechanism including a friction rotary member being configured to contact said second and intermediate rotary members in said rotational direction, said friction mechanism including a pin being configured to extend in said gourd-shaped hole; a friction suppressing mechanism being configured to prevent said friction mechanism from operating within a prescribed angular range; and an elastic member being configured to soften impact between said pin and said protruding section.
