  "description_excerpt": "1. Field of the Invention\n\nThe present invention relates to an introducing device system which reduces an amount of operation force for operating a bending operation device configured to pull a pulling member that causes a bending portion to bend.\n\n2. Description of the Related Art\n\nEndoscopes, for example, as introducing devices for introducing an insertion portion into a subject, are used in medical fields, industrial fields, and the like. In the case of the endoscopes in medical fields, observation, etc., are performed by inserting an insertion portion into a body. On the other hand, in the case of the endoscopes in industrial fields, observation, etc., are performed by inserting an insertion portion into a piping or into a construction such as an engine.\n\nAn endoscope generally includes an observation optical system at a distal end portion of an insertion portion. Furthermore, such an endoscope includes a bending portion that bends in up, down, left and right directions, for example, on the distal end side of the insertion portion. In addition, the endoscope includes, at the proximal end of the insertion portion, an operation portion including a bending operation device for causing the bending portion to bend.\n\nA bending knob which is rotationally moved, an operation lever which is tilted, etc., are publicly known as the bending operation device. Such a bending operation device and, for example, a distal end bending piece constituting a bending portion are coupled to each other with wires as pulling members.",
