Abstract: An endoscope includes an image pickup module having an optical axis that defines a visual field direction and provided with an electric contact, a cable that is disposed on a proximal end side of the image pickup module and transfers an image pickup signal generated by the image pickup module, a channel provided beside the image pickup module, and a movable board electrically connecting the electric contact and the cable to transfer the image pickup signal and including a movable portion capable of forming a curved surface that is freely displaceable in an optical axis direction. The movable portion of the movable board is arranged at a position where a distance between the curved surface and the channel is longer than a distance between the curved surface and the optical axis.

Abstract: A holding mechanism has a first holding portion and a second holding portion. The first holding portion holds a part of an endoscopic guide member which is exposed to the outside of an endoscope. The second holding portion is disposed at a position different from that of the first holding portion. The second holding portion holds another part of the endoscopic guide member which is exposed to the outside of the endoscope, in an orientation different from an orientation of the first holding portion.

Abstract: A bending operation mechanism includes a bending operation member configured to bend a bending portion, a wire pulling member configured to rotate along with rotation of the bending operation member, a lock operation member supported to a rotational axis, a cam member having a cam surface and integrally provided with the lock operation member, and a brake member having a cam follower surface capable of sliding relative to the cam surface. The cam member moves along with rotation of the lock operation member. The brake member moves in a direction in which a contact surface contacts a circumference of the wire pulling member as the cam follower surface slides on the cam surface in accordance with movement of the cam member.

Abstract: A bendable tube segment includes annular members and wire insertion portions. The wire insertion portion is provided on the annular member to shift by a third angle, which is an obtuse angle smaller than a first angle, in the same direction as the first angle. The wire insertion portion is provided on the annular member to shift by a fourth angle, which is an acute angle larger than a second angle, in the same direction as the second angle.

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.
