Claims

[Scope of utility model registration request]

The case body and the lid body are pivotally connected by a fulcrum pin,
In a cassette case in which the case body is opened and closed by rotation of the lid body about the fulcrum bottle, the case body or the lid body is spaced apart from the fulcrum point and is connected to the lid body or the case body. A convex portion that comes into sliding contact is provided, an arc-shaped guide groove is provided along the sliding contact portion with the convex portion of the lid body or the case body, and a plurality of retainers that can be engaged with the convex portion are provided on the bottom surface of the guide groove. A mating hole is provided, and a concave portion is provided on the bottom surface of the guide groove between the engaging holes, and the convex portion is engaged with the engaging hole to restrict rotation of the lid body and to prevent the guide groove from rotating. The concave portion reduces the contact pressure between the bottom surface and the convex portion, and when the lid body is opened at a predetermined angle or more relative to the case body by opening one end of the guide groove, the concave portion reduces the contact pressure between the bottom surface and the convex portion. A cassette case characterized in that the convex portion is configured to protrude from the open end of the guide groove.
