Abstract
A bending mechanism includes: an elongated support member; a swivel that is pivotably connected to a distal end of the support member; a first link that can transmit a driving force applied at the proximal end, to make the swivel pivot with respect to the support member; a second link that can transmit a driving force applied at the proximal end, to make the swivel pivot with respect to the support member; and a connector that is provided on at least one of the first and second links and that can switch the coupled state of one of the first and second links when a pivoting angle of the swivel exceeds a threshold such that the permissible stress of the one of the links has become less than the permissible stress of the other.
