ABSTRACT:
A recording tape cassette has a case formed from an upper case and a lower case, and in which a reel, on which a recording tape is wound, is accommodated; a shaft standing erect at the lower case; a guide roller fit with play at the shaft; and a holding hole provided at the upper case, and into which a distal end of the shaft is inserted with play. The holding hole has a guide surface which, when the case deforms, makes the distal end of the shaft move in a predetermined direction. In accordance with the recording tape cassette, conveying stability of the recording tape trained around on the guide roller can be ensured.
