Abstract

PURPOSE:To make a magnetic tape cassette for VTR or the like small-sized and thin with a simple constitution, by forming a tooth part on the outside circumference of a reel flange of a reel hub to transfer a rotation driving force. CONSTITUTION:A tooth part 86 is formed on the outside circumference of a reel flange 84 of a reel hub 82. This tooth part 86 engages with a driving tooth part 58 inserted from a switching part 88 of a cassette 50, and a rotation driving force is transferred to this tooth part 86, and thus, a reel is turned without a reel base or the like. By this simple constitution, a magnetic tape cassette for VTR or the like is made small-sized and thin.
