A tape cassette comprising a housing made up of upper and lower casings, a pair of reels around which a tape is wound and contained altogether in the housing, and a pair of cylindrical resin tape guides having a height greater than the width of the tape, said tape guides being securely fitted to corresponding tape guide posts also having a height greater than the width of the tape and provided in the lower casing. Each tape guide post has a press-fit rib formed in one piece with it on the side where the tape does not come in contact with the tape guide on it. The rib has a vertical height greater than half that of the tape guide and serves to make the dimensions of the tape guide post surface on the tape-contacting side greater than the inside diameter of the tape guide before being press-fitted.
