するカメラ等における駆動力伝達用連結機構。[Scope of Claim for Utility Model Registration] In a driving force transmission connection mechanism that transmits the driving force for moving the lens from within the camera body to an interchangeable lens that is detachably attached to the camera body, A flat convex part is formed,
One of the connecting members consists of a cylindrical shaft with a cone-shaped alignment surface formed on the peripheral edge of the tip surface, and a flat convex portion of the one connecting member is fitted into the center of the tip surface, and the protrusion The other is made of a cylindrical shaft, which is formed with a slotted recess that is deeper than the amount of protrusion, and has a bowl-shaped alignment surface formed on the peripheral edge of the tip surface so that the cone-shaped alignment surface of the one connecting member comes into close contact with the other. One of the above-mentioned connecting members is disposed on the camera body side and the other on the interchangeable lens side, and the driving force is transmitted to the connecting member on the camera body side, and both the connecting members are connected. A coupling mechanism for transmitting driving force in a camera or the like, characterized in that when coupled, the cone-shaped centering surface and the mortar-shaped centering surface are brought into close contact with each other for centering.
