ABSTRACT:
In a lens-fitted photo film unit having a main body portion containing a roll of unexposed photo filmstrip and having photographic mechanisms mounted thereto, and outer walls covering the main body portion, any clearance provided for relative movement between two adjacent members is made to be not less than any gap in outer walls of the film unit. Particle diameters of the sands, which may enter at any gap in the outer wall, are less than the gap and thus less than any clearance, so that the clearance is not clogged up with the sands.
