Abstract
An anti-reverse claw is in mesh with a winding dial of a lens-fitted photo film unit. The anti-reverse claw has a pair of welded pieces. The welded pieces go behind a rear cover of the lens-fitted photo film through a pair of holes formed in the rear cover. After assembling, a welding head is applied to the rear side of the rear cover to apply heat. The welded pieces and a separation plate are melted and mixed together, so that the anti-reverse claw is firmly fixed to the rear cover.
