Abstract
A bending manipulation device for endoscope wherein a pair of control wires are taken up by a pulley provided in and given a rotary motion by the main control portion of the endoscope, and one of control wires extended out from the pulley corresponding to the turning operation thereof is taken up by the pulley while the other is paid out from the pulley, thereby enabling the bending manipulation to be carried out. The groove of the above pulley is formed in the shape of a spiral continuously extending in the peripheral direction of this pulley and is used in common by the above pair of control wires. One part from the one end of the groove and the other part from the other end of the groove are arranged side by side and in parallel with each other. Each of control wires is alternately taken up on the groove of the pulley corresponding to the turning direction of the pulley.
