An endoscope includes: an operation portion provided on a proximal end side of an insertion portion one pair of pulling members extending from a bending portion a pulley rotated by a motor rotating bodies that are elastically deformable and arranged on the pulley a suspension frame to which the pulling members are fixed a manipulator provided to project from the operation portion, the manipulator being capable of applying an amount of force of pulling a part of a pulling member on the insertion portion side using a frictional resistance generated as a result of, upon a tilting operation being performed, the pulling member being pulled to reduce a diameter of the corresponding rotating body and the rotating body being thereby brought into contact with the pulley and a force amount adjustment section capable of changing the amount of force of pulling by making an adjustment of a friction generation state.
