Abstract
A rotation clamping mechanism includes a rotating member and at least two engagement members that are attached to the rotating member and transmit rotational power. The engagement members engage a rotated object placed in a predetermined positional relationship with the engagement members. The rotated object is rotated by rotating the rotating member. The engagement members are supported on the rotating member so as to swing to an engagement position where power is transmitted to the rotated object and to a release position where engagement is released. The rotation clamping mechanism further includes: an opening/closing mechanism that moves the engagement members between the engagement position and the release position; and a biasing member that biases the engagement members toward the engagement position. At the engagement position, the engagement members clamp the rotated object in a floating state with the engagement members pressed onto the rotated object by the biasing member.
