An anti-reverse claw (22) is in mesh with a winding dial (18) of a lens-fitted photo film unit. The anti-reverse claw (22) has a pair of welded pieces (28a,28b). The welded pieces (28a,28b) go behind a rear cover (6) of the lens-fitted photo film through a pair of holes (30a,30b) formed in the rear cover (6). After assembling, a welding head (40) is applied to the rear side of the rear cover (6) to apply heat. The welded pieces (28a,28b) and a separation plate (31) are melted and mixed together, so that the anti-reverse claw (22) is firmly fixed to the rear cover (6), so as to be made useless by opening and recharging the film unit. <IMAGE> |
