PURPOSE:To accurately position a case member on a camera main body side by moving the casing member back and forth in one direction according as a male screw is tightened or loosened. CONSTITUTION:A female screw 35 in which the male screw 34 is screwed is provided at the edge of a mount 30 in the right-and-left direction of the camera, and a coil spring 36 elastically compressed is allowed to intervene between the screw 35 and the inner side of a through hole 33b in a state where the screw 34 exists in the spring 36. With such constitution, the casing member 33 is pressed by the spring 36 in a direction where the member 33 abuts on the head of the screw 34 (a right direction in figure), and the member 33 is moved in the right-and-left direction of the camera while the member 33 is guided and moved by the mount 30 according as the screw 34 is tightened or loosened. Since the member 33 is moved back and forth in one direction according as the screw 34 is tightened or loosened, the member 33 is easily and accurately positioned on the camera main body side (mount 30). |
