Endoscope imaging device and endoscope in which drive malfunction of lens drive unit is suppressed

An endoscope imaging device including, on a distal end side, a plurality of lenses that include a first movable lens which is movable along an optical axis direction, and a sensor that captures a subject image formed by the plurality of lenses, the endoscope imaging device comprising:

• a lens accommodating portion that accommodates the first movable lens which is movable along the optical axis direction among the plurality of lenses;
• a housing that is disposed alongside the lens accommodating portion as viewed from the optical axis direction;
• a coupling portion that couples the lens accommodating portion and the housing to each other in a state in which the lens accommodating portion and the housing communicate with each other;
• a lens drive unit that is accommodated in the housing, wherein the lens drive unit includes a movable lens holding portion that holds the first movable lens, and the movable lens holding portion is disposed across the lens accommodating portion and the housing through the coupling portion;
• a receiving portion that is provided at an end part of the housing or an end part of the lens accommodating portion in an extension direction of the coupling portion as viewed from the optical axis direction;
• a pressing member that is provided at the end part of the lens accommodating portion or the end part of the housing facing the receiving portion in the extension direction and presses the lens accommodating portion or the housing;
• a first restricting portion that restricts a position of the lens accommodating portion in a cross direction crossing the extension direction of the coupling portion;
• and
• a second restricting portion that restricts a position of the housing in the cross direction crossing the extension direction of the coupling portion,
• wherein the receiving portion, the first restricting portion, and the second restricting portion are each formed as part of a distal end body that supports the lens accommodating portion and the housing,
• wherein the extension direction of the coupling portion is a first direction that passes through a center point of the lens accommodating portion and a center point of the housing when viewed from the optical axis direction,
• wherein the movable lens holding portion comprises:
• a tubular guide portion accommodated in the housing;
• a lens frame that holds the first movable lens and is accommodated in the lens accommodating portion;
• and
• a coupling portion that couples the tubular guide portion and the lens frame to each other,
• wherein the coupling portion of the movable lens holding portion passing through the coupling portion that couples the lens accommodating portion and the housing so that the first movable lens moves along the optical axis direction.
