ABSTRACT:
A magnetic tape cassette capable of effectively eliminating a variation in pressure of the elastic pad element during traveling of a magnetic tape and preventing a variation in tension of the tape, to thereby ensure stable and safe traveling of a magnetic tape. The magnetic tape cassette is so constructed that an elastic pad element which is formed into a dogleg shape is supported at the bent portion thereof on a support rod arranged in a casing and a first section of the elastic pad element extending between the support rod and one end of the pad element is arranged so as to extend substantially in the tangential direction of a tape guide roller at the position of the guide roller at which a holding portion of the elastic pad element acts on the guide roller. The first section may be arranged in proximity to the portion of the magnetic tape between the one reel and the guide roller when the holding portion is defined in such a manner as in a conventional magnetic tape cassette typically constructed.
