伝達機構。[Scope of Claim for Utility Model Registration] A main drive shaft that is supported within a hollow shaft and transmits rotational driving force, a main drive gear provided at the end of the main drive shaft, and a main drive gear that is mounted on a tool post and receives rotational power. A rotation transmission mechanism for a tool post comprising a rotary tool unit equipped with an output gear that rotates a tool, and an intermediate gear that is always meshed with the output gear and can be engaged with and disengaged from the drive gear by moving in the axial direction, A cam that moves the intermediate gear in the axial direction is disposed on the back side of the tool post, and a shifter rod that comes into contact with the cam and moves the intermediate gear is slidably fitted onto the central axis of the intermediate gear shaft. a first shifter spring is arranged inside the intermediate gear shaft to always press the shifter rod toward the cam, and the intermediate gear is slidably fitted to the intermediate gear shaft so that the intermediate gear is aligned with the axis. A spring receiving pin is passed through the shifter rod in a right angle direction, and an elongated hole is provided in the shifter rod to allow the spring receiving pin of the intermediate gear to pass through, and when the shifter rod is apart from the cam, the spring receiving pin is inserted into the shifter rod. A rotation transmission mechanism in a tool rest, characterized in that a second shifter spring is interposed between the spring receiving pin and a flange provided on the shifter rod so as to come into contact with the rear end of the elongated hole.
