1. An imaging apparatus for endoscope comprising:
a coupler configured to hold an endoscope that captures and emits an image of a subject;
an imaging apparatus main body connected to the coupler so as to be relatively rotatable with respect to the coupler around an optical axis of the endoscope, the imaging apparatus main body being configured to capture the image of the subject emitted from the endoscope; and
a posture keeping member provided between the coupler and the imaging apparatus main body and configured to maintain a posture of the imaging apparatus main body with respect to the optical axis of the endoscope by generating a desired physical quantity between the coupler and the imaging apparatus main body while abutting on each of the coupler and the imaging apparatus main body, wherein
the posture keeping member includes
an elastic member; and
a contact member fixed to an end, on the coupler side, of the elastic member, the contact member being configured to generate the desired physical quantity between the coupler and the imaging apparatus main body while abutting on the coupler, and wherein
the imaging apparatus main body includes an exterior casing including a recess facing the coupler,
the elastic member is placed in the recess, and
the contact member is partly placed in the recess to be guided along a side surface of the recess, and is placed so as to move toward and away from the coupler.
