Abstract
There is disclosed a guide device for guiding an endoscope. The guide device includes an elongate, tubular guide body so flexible as to be bent. An insertion portion of the endoscope is adapted to be inserted into and guided by the guide body. A direction indication mechanism is mounted on an inner periphery of a front end portion of the guide body. The direction indication mechanism includes an annular holder member, and a displacement member supported by the annular holder member for displacement circumferentially of the holder member under the influence of gravity. The endoscope itself is not provided with a direction indication mechanism, and by observing the displacement member from the inner side of the front end portion of the guide body, the direction is confirmed.
