Abstract
A camera accessory device which not only makes it possible to prevent a camera-side accessory shoe from being scratched thereby, but also encores positive electrical connection between the camera accessory device and a camera. The camera accessory device comprises a lock lever, a shoe bracket for engagement with the camera-side accessory shoe, contact pins for contact with respective electric contacts of the camera-side accessory shoe, a contact spring-holding member, and an accessory shoe-holding member which moves, in accordance with rotation of the lock lever, to a shoe member-locking position or to a shoe member-unlocking position. The contact pins are urged by the holding members such that urging forces applied to the electric contacts become larger when the accessory shoe-holding member has moved to the shoe member locking position than when the same has moved to the shoe member unlocking position.
