Claims

[Scope of utility model registration request]

A disk cartridge in which a case body is constructed by combining a case divided into two parts into an upper and a lower part using an ultrasonic welding means,
A first concave and convex portion and a second concave and convex portion formed on the inner wall of one of the upper and lower cases and the inner wall of the other case and that fit together are arranged on the front side of the case body. The case and the case are arranged on both sides in the width direction, and are fitted into each other to form the first concave and convex portions and the second convex portion.
A third concave and convex portion for relative positioning of the upper and lower cases together with the concave and convex portions are disposed on the rear side of the case body.
