Abstract: An endoscope includes a pulley provided in an operation portion, having an outer diameter larger than an inner diameter of an endoscope insertion portion, and configured to wind a wire connected to a bending portion; and a wire guard that is arranged to cover a predetermined range of an outer peripheral portion of the pulley, and includes a guide wall arranged to extend within a range of a radius of the pulley from a contact point position at which the wire in contact with the pulley is separated from the pulley in a longitudinal axis direction of the operation portion. The wire guard includes two members each formed in a substantially semicircular plate shape, and coupling parts formed in arc shapes extending from both end portions of the two members and configured to couple the two members.

Abstract: A wire fixing structure includes: a first hole portion through which a wire passes; and a second hole portion which is formed in a direction orthogonal to the first hole portion and communicates with the first hole portion. The wire includes: a first portion which is inserted into and is disposed in the first hole portion; a second portion which is extended from the first hole portion and wound around the outer peripheral portion of a wire fixing member; and a third portion which is inserted into and is disposed in the first hole portion again after the second portion is wound around the outer peripheral portion. The fastening member is inserted into the second hole portion and fixes the first portion and the third portion by pressing in the first hole portion.
