Abstract
A case for holding a magnetic tape cassette comprises a case body and a cover pivotally joined together by a pair of pivots fitted in corresponding pivot-receiving holes, with arcuate protuberances formed respectively around the pivots and pivot holes in such a manner that, when the pivots have been fitted in the holes, the both protuberances coact to keep the opposing side walls of the case body and the cover apart from each other, the protuberances themselves being arranged so as not to overlap each other. The pivots protrude inwardly from the side walls of the case body, the pivot holes are formed in the side walls of the cover, and the arcuate protuberances are formed, one for each, on the inner faces of the side walls of the case body and on the outer faces of the side walls of the cover. The protuberances of the case body are formed to extend semicircularly through an angle of 180 degrees around the pivots, and the protuberances of the cover extend through an angle of 90 degrees around the pivot holes.
