    Abstract: A driving force transmission mechanism for an endoscope includes an insertion portion, an operation portion, an electric motor, an output member, a rotation transmission member, an inside plane, a first plane, a second plane and a third plane configured to come into contact with a proximal end of the output member when at least part of the second plane comes into contact with the inside plane to thereby restrict the rotation transmission member from moving toward the distal end side in the axial direction with respect to the output member.

    Abstract: A rotary unit includes a first taper tubular portion which is contiguous to a first axial direction side of a unit main body portion and in which a first unit end of the rotary unit is positioned, an outer diameter of the first taper tubular portion becoming smaller toward the first axial direction. The rotary unit includes a first projecting portion extended on an outer peripheral portion of the first taper tubular portion with projecting toward an outer peripheral direction and wound toward a first around-axis direction as the first projecting portion extends from the first axial direction toward a second axial direction.

    Abstract: An inserting instrument includes a first flexible tube section having a flexibility lower than a spiral tube, a second flexible tube section having a flexibility lower than the spiral tube and equal to or higher than the first flexible tube section in a state where the second flexible tube section is not covered with the spiral tube. The flexibility of the second flexible tube section is lower than that of the first flexible tube section when the second flexible tube section is covered with the spiral tube. The inserting instrument includes a third flexible tube section provided on the proximal direction side with respect to the second flexible tube section and having a flexibility lower than the first flexible tube section.

    Abstract: An insertion device includes an idle state detector detecting an idle state in which an insertion section does not move in directions along the longitudinal axis when a rotation unit rotates in directions around the longitudinal axis, and a movement displacement calculator calculating a rotation direction and amount of the rotation unit based on a driving direction and amount of the driving member and calculating a movement displacement of the insertion section from a reference position in directions parallel to the longitudinal axis based on the rotation direction and amount of the rotation unit. The movement displacement calculator calculates the movement displacement of the insertion section so that a movement amount of the insertion section in the longitudinal directions while the idle state being detected is zero.

    Abstract: An endoscope includes an insertion section including first and second bending portions, a first bending drive mechanism to bend the first portion in the upward direction, first and second distal side-traction members passing inside the insertion section and a proximal side-traction member. The first portion can bend in the upward direction. The second portion is on a proximal side of the first portion and can bend in the upward direction and in right and left directions along a circumferential direction of the upward direction. The first distal side-traction member is fixed to a position of the second portion, separated from the upward direction toward the right. The second distal side-traction member is fixed to a position of the second portion, separated from the upward direction toward the left direction. The proximal side-traction member pulls the first and second distal side-traction members in conjunction with the first bending drive mechanism.
