Claims

[Scope of utility model registration request]

(1) At least one end of a light-shielding bellows provided inside the camera body for guiding subject light from the photographic lens to the exposure surface, and an opening facing the opening of the bellows and an opening facing the camera body or lens barrel. A fixing member having a coupling part that can be coupled is provided, an engaging part that can engage with the coupling part is provided on the camera body or the lens barrel, and the fixing member is pushed into the camera body or the lens barrel to achieve the above coupling. 1. A bellows mounting mechanism for a camera, characterized in that the fixing part is tightly coupled to a camera body or a lens barrel due to the spring properties of the retaining part or the retaining part.

(2) The bellows mounting mechanism for a camera according to claim 1, wherein the coupling portion or the engaging portion has elasticity that exerts an urging force in the coupling direction when coupled. .

(3) Practical use characterized in that the periphery of the opening of the fixing member and the periphery of the opening of the camera body or lens barrel facing it have fitting portions that overlap each other perpendicularly to the mating direction. A bellows mounting mechanism for a camera according to claim 1 or 2 of the patent registration claim.
