Abstract:
An elastic coupling mechanism comprising:a first elastic member having first and second rotationally facing ends; a second elastic member having first and second rotationally facing ends, said second elastic member disposed radially inward from said first elastic member: a first rotating member having first abutting parts that abut against said first and second rotationally facing ends of said first elastic member; a second rotating member having second abutting parts that abut against said first and second rotationally facing ends of said second elastic member, said second rotating member being configured to support a first axial side of said first and second elastic members; and an intermediate member connecting said first and second elastic members together in a rotating direction such that said first and second elastic members compress together so as to act as if said first and second elastic members were arranged end to end in the rotating direction, said intermediate member being supported by said second rotating member and engaged with said second rotating member so as to move in the rotating direction, said intermediate member supporting a second axial side of said first and second elastic members, said second axial side being axially opposite said first axial side.
