Abstract
An endoscope including a bending portion in an insertion portion comprises multiple pulling members, an operation device, a driving force transfer mechanism and a biasing mechanism. The multiple pulling members are mounted on the bending portion. The operation device generates a driving force for pulling the pulling members in conjunction with a turning operation. The bending portion is bent by the operation device between an approximately straight state and a bending state. The driving force transfer mechanism transfers the driving force generated in conjunction with the turning operation of the operation device to the pulling members. The biasing mechanism provides the driving force transfer mechanism with a biasing force for turning the operation device in a reverse direction to the turning operation direction in a state where the bending portion is bent by turning the operation device.
