PURPOSE:To surely execute connection and the transmission of a driving force by holding, at least, either a driving rotation transmitting shaft or a follower rotation transmitting shaft with a fine margin to shake and installing a meshing and engaging guide means for a driving matching end surface and a follower matching end surface between both rotation transmitting shafts. CONSTITUTION:The leading edge positioning part 10 of a mount positioning member 9 is inserted and fitted in a pierced hole formed on an attachable/detachable mount 3 from the inside and always energized with a spring 8 in a protruding direction from the surface of the mount. A 1st driving shaft 13 functioning as a driving member installed on a body 1 side, is formed so that it has sufficient gap with respect to the inner diameter of the positioning part 10. The leading edge part of a 2nd driving shaft 60 protrudes from the pierced hole of the attachable/detachable mount 54 into a mount positioning recess part 64. An engaging recess part 62 is formed on the end surface of the leading edge part and the engaging recess part 62 and an engaging pawl 17 constitute a meshing clutch corresponding to the engaging pawl 17 of the 1st driving shaft 13 on the camera body 1 side. Even if an error occurs in case of fitting a lens barrel on a camera main body, they can be surely connected and the d riving force can be surely transmitted. |
