    a fifth force-applying member that is provided on at least one of the paired clamps that applies a pressing force sandwiching the optical fiber;

    a first cam mechanism that is configured to be displaced by being driven to rotate by motor control and thereby controls to grasp the optical fiber due to the displacement;

    at least two or more heaters that are arranged to face each other so as to sandwich or the sleeve;

    a second force-applying member that applies a pressing force to at least one or more of the two or more heaters with the sleeve interposed therebetween; and

    a third cam mechanism that is disposed on a camshaft on which the first cam mechanism is provided or is disposed on the other camshaft parallel to the camshaft, is configured to be displaced by being driven to rotate by the motor control, and thereby controls the heaters to press the sleeve due to the displacement, whereinthe same motor controls a force of each of the force-applying members with respect to the clamps and the heaters by the first and third cam mechanisms.
