PROBLEM TO BE SOLVED: To provide an insertion device that enables an operator to actually feel a rotation direction and a rotational speed of a power spiral tube intuitively.SOLUTION: An insertion device includes: an insertion part 10 extended along a longitudinal axis from a proximal end direction toward a distal direction; a power spiral tube 17 including a spiral fin part 18 spirally extended along the longitudinal axis, and rotatably provided in the longitudinal axis circumferential direction to the insertion part 10 in an outer peripheral direction side of the insertion part 10; a first motor 23 for generating a driving force to rotate the power spiral tube 17 by being driven; an operation part 11 provided at the proximal end side of the insertion part 10; a rotational direction/speed detection circuit for detecting a rotational direction and the rotational speed of the power spiral tube 17; and an LED provided in the operation part 11, and displaying the rotational direction and the rotational speed of the power spiral tube 17 synchronously with the detection result of the rotational direction/speed detection circuit.SELECTED DRAWING: Figure 2 |
