Abstract
A bending mechanism includes: an elongated support member; a swivel that is supported at a distal end of the support member so as to swivel around an axis that intersects a longitudinal axis of the support member; a transmitter that are arranged along the longitudinal axis of the support member, transmits a driving force applied at a proximal end thereof, and makes the swivel swivel relative to the support member; and a regulator that regulates stress generated in the transmitter at each swivel position of the swivel with respect to the support member such that the stress does not exceed a prescribed threshold.
