Abstract
A rotational torque adjustment apparatus is used to adjust the rotational torque of a rotational member secured to a rotational shaft for integrally rotating with the rotational shaft. The rotational torque adjustment apparatus includes a friction member for contacting with the rotational member to apply a frictional load to the rotational member, a brake member for holding the frictional member thereon, a pressing member for pressing the friction member held on the brake member with a predetermined pressure against the rotational member, and a guide section for holding the brake member for movement thereon. The brake member is moved in a radial direction of the rotational member along the guide section to vary the rotational torque of the rotational member.
