<p>PROBLEM TO BE SOLVED: To provide an endoscope device which can accurately change its focal distance and is easy to downsize.SOLUTION: An endoscope device including an imaging element 23 for imaging a subject through lenses including a movable lens 21 comprises: a rotation member 11 configured to be rotatable around a rotation axis J2; a motor for rotatably driving the rotation member 11; a movable lens holding unit part 14 which has a pin 15 for contacting with a part 11b of the rotation member 11 and holds the movable lens 21; and a spring 16 for energizing the pin 15 for the rotation member 11 side. The rotation member 11 includes: a part 11b in a cylindrical shape extending in the optical axis direction; and a part 11a in a cylindrical shape which is provided so as to protrude from an end face on the subject side of the part 11b and is thinner than the part 11b. The end face of the part 11b includes a contact face on which the pin 15 abuts and whose height in the optical axis direction changes continuously in the circumferential direction of the part 11b. The movable lens holding unit part 14 is fit movably in the optical axis direction at the part 11a.</p> |
