ツト。 The magnetic tape cassette has a pair of hubs rotatably supported within a case body formed by a pair of upper and lower half cassettes, and a magnetic tape is wound between the pair of hubs so as to be freely movable. At least the portion of the annular rib forming the hub hole that rotatably supports the hub, which faces the hub, is made of a synthetic resin having a higher coefficient of friction and higher elasticity than the resin constituting the case body. A magnetic tape cassette characterized in that:
