Zusammenfassung: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.
