1. A coating removal device for removing a coating of an optical fiber along an axial direction of the optical fiber, the coating removal device comprising:
a heating portion including a cutting blade making a cut in the coating of the optical fiber, and a heater heating a part of the coating that is closer to a tip thereof than the cutting blade;
a main body portion including a control board electrically connected with the heater;
a holding portion holding the optical fiber, the holding portion being provided on an opposite side opposite to the heater with the cutting blade being located between the holding portion and the heater;
a slide mechanism allowing the holding portion to slidably move with respect to the heating portion such that the holding portion is distanced away from the heating portion in the axial direction; and
an assisting mechanism providing the holding portion with a first urging force acting in the axial direction to assist a sliding movement of the holding portion in a state where the holding portion is holding the optical fiber,
wherein:
the main body portion, the heating portion and the holding portion are located in this order in the axial direction,
the assisting mechanism includes a restriction member using a second urging force acting in a predetermined direction to restrict provision of the first urging force to the holding portion in a state where the holding portion is not holding the optical fiber,
the heating portion includes a vibration notification portion giving information to an operator by vibrating, and
the vibration notification portion vibrates in a direction generally perpendicular to the predetermined direction.
