Motor and recording and/or reproducing apparatus using the motor

A motor comprising:

• a fixed member fixedly arranged on a chassis;
• a rotational member arranged opposedly of said fixed member, said rotational member including a material integrally formed hollow cylindrical rotational shaft extending upward from said rotational member;
• and
• a rolling member interposed between said rotational member and said fixed member;
• wherein shapes of said rotational member and said rotational shaft are integrally formed by bending a single thin walled plate into said shaped.

A motor comprising:

• a fixed member fixedly arranged on a chassis;
• a rotational member arranged opposedly of said fixed member, said rotational member including a rotational shaft;
• and
• a rolling member interposed between said rotational member and said fixed member;
• wherein said rotational member and said rotational shaft are integrally formed from a single plate;
• and
• wherein said fixed member includes an inner peripheral edge surrounding a central opening, and a plurality of petal-like protrusions extending from the inner peripheral edge, some of said petal-like protrusions being bent to form bent portions for detachably connecting said fixed member to said chassis.

A recording and/or reproducing apparatus for carrying out reading and/or writing date from/to a disk rotatably driven by a motor, wherein said motor of said apparatus comprises;

• a chassis;
• a fixed member fixedly arranged on said chassis;
• a rotational member arranged opposedly of said fixed member, said rotational member including a material integrally formed rotational shaft;
• and
• a rolling member interposed between said rotational member and said fixed member;
• wherein shapes of said rotational member and said rotational shaft are integrally formed by bending a single thin-walled plate into said shapes.
