Abstract

PURPOSE:To facilitate the replacement of accessories, by giving a slack preventing function between a holding material for accessories and a filter. CONSTITUTION:Under the state where a holding material 2 for accessories is pulled out from a lens barrel, a knurling face 6c of a lock pin 6 energized in directions of arrows A and B by coil springs 7-9 is placed a distance apart from the outside circumferential face of a filter, and the end face of a push pin 4 is projected from a plane 2f of the connection part of the holding material 2, and the replacement of accessories is possible. When the holding material 2 is inserted to the aperture part of the lens barrel after attachment of accessories, the projecting face of the pin 4 is pushed in a direction opposite to the direction of the arrow A, and the pin 6 is pushed through a connecting pin 5 against the force of the spring 9. Thus, the pin 6 and a filter 1 are meshed with each other, and the filter 1 is detained by the holding material 2, thereby preventing the slack due to vibration or the like.
