Abstract
A device for electrically connecting a lens barrel and a camera body includes a connector provided integrally with the fixed cylinder of the lens barrel along the cylindrical surface of the fixed cylinder. The connector has a movable contact resiliently displaceable in the diametral direction of the cylinder. The movable contact is urged against a contact piece provided on the camera body upon completion of the mounting of the lens barrel to the camera body. The camera body is provided with an inclined surface for displacing the movable contact in the diametral direction against the resilient force during the mounting operation of the lens barrel to the camera body.
