Magnetic disk cartridge provisionally assembled utilizing at least one rivet

摘要

A magnetic disk cartridge has a cassette shell made of first and second cassette shell halves formed with pairs of holes for insertion of rivets. The rivets include a flange, elastically deformable bulged portions having tapered surfaces at their distal ends and sloped provisional retaining surfaces at their proximal ends. The cassette shell halves are provisionally assembled by inserting the rivets into the insertion holes from the side of the first cassette shell half to bring the sloped provisional retaining surfaces into engagement with sloped engagement surfaces in the rivet insertion holes of the second cassette shell half. The provisionally assembled cassette shell halves can be easily disassembled if necessary.
