付切削装置。[Claims for Utility Model Registration] A retracting mechanism main body; an eccentric member having a first cylindrical surface and a second cylindrical surface eccentric to each other, and rotatably supported by the retracting mechanism main body at the first cylindrical surface; a tool holder that is rotatably fitted to the second cylindrical surface of the eccentric member and prevented from rotating relative to the retract mechanism main body, and that moves in the radial direction as the eccentric member rotates; and a tool holder that is integral with the eccentric member. a reciprocating actuator that includes a rotating member that rotates in a straight line; and an output member that moves back and forth in a linear manner; a motion converting mechanism that converts the reciprocating motion into a reciprocating rotational motion, and in which a retracting motion is applied to the cutting tool held in the tool holder by the operation of the reciprocating actuator. A cutting device with a cutting tool retract mechanism, characterized in that it includes a screw mechanism consisting of a male thread and a female thread that are square or larger.
