Abstract
A brake for a bending control device of an endoscope comprising a driving device rotatably provided in a control part for pulling a control wire, a rotary shaft rotating together with the driving device, a fixed shaft fixed in the control part in concentrical relation to the rotary shaft, a friction member accommodating chamber defined in an annular shape between the fixed and rotary shafts, and a resilient friction member loaded within the friction member accommodating chamber in a compressed state. When the control wire is pulled by rotating the driving device, the rotary shaft rotates together with the driving device. As a result, friction resistance occurs between the friction member loaded in the friction member accommodating chamber on the one hand and the rotary and fixed shafts on the other, thus applying the brakes to the driving device.
