1. A fixing device for fixing a tube for a medical apparatus comprising:
an arm portion that extends in a long-axis direction;
a fixation portion that is to fix a tube; and
a rotation portion that is disposed between the arm portion and the fixation portion directly on the long-axis of the arm portion and that allows the fixation portion to be rotated about the long-axis direction of the arm portion;
wherein the rotation portion includes:
a holding part that is capable of holding the fixation portion;
a hose receiving rotating part that is held by the holding part,
a hose rotation receiver that is disposed between the hose receiving rotating part and the arm portion, and that is rotated in synchronization with the hose receiving rotating part;
a metal plate which is disposed between the hose rotation receiver and the arm portion, which provides the hose rotation receiver with an elastic force, and in which a through hole that passes through the metal plate in the long-axis direction of the arm portion is formed;
a first plate-like member which is disposed between the metal plate and the hose rotation receiver, which reduces the friction force generated when the hose rotation receiver is rotated, and in which a through hole that passes through the first plate-like member in the long-axis direction of the arm portion is formed; and
a second plate-like member which is disposed between the hose rotation receiver and the hose receiving rotating part, which reduces the friction force generated when the hose rotation receiver is rotated, and in which a through hole that passes through the second plate-like member in the long-axis direction of the arm portion is formed.
