ABSTRACT:
A tape cassette has a shutter which can be opened and closed for accommodating a magnetic tape which records information such as music and reproduces recorded information. The shutter is made of thermoplastic resin and hardly generates abraded powders as a result of the sliding of the shutter in contact with the casing. The shutter has engaging portions in specific configurations so as to prevent the shutter from being dislocated from the casing.
