Claims

[Claim for Utility Model Registration] Mirror box side walls are provided at the left and right ends of an aperture formed in the camera body in parallel with the optical axis of the photographic lens, and a light shielding member is provided along the opening surface of the aperture. A longitudinally running focal plane shutter device that travels in the vertical direction is disposed behind the mirror box side wall, and a cartridge is formed of a cylindrical outer wall sandwiching the mirror box side wall and the focal plane shutter device. In a single-lens reflex camera having a structure in which a chamber and a spool chamber are arranged opposite to each other on the left and right, the light shielding member and the camera body main body are formed to ensure that the light shielding member blocks light at the left and right ends of the aperture portion. a polymerization part of
In a space formed by the side wall of the mirror box and the cartridge chamber or the spool chamber,
A bulging space for tilting the film storage position toward the optical axis side is formed by bulging at least one of the outer walls forming the cartridge chamber or the spool chamber. A body structure for a single-lens reflex camera, characterized in that the body structure is formed by an outer wall of a bulging space that is a separate member, and the outer wall of the bulging space and the side wall of the mirror box are integrally formed.
