Claims

[Scope of Claim for Utility Model Registration] A speed-increasing gear train that increases the speed of input rotation and transmits it; an overload prevention mechanism that idles and interrupts rotation transmission when a rotating body having a cam portion formed with a first tapered surface inclined in the direction and a second tapered surface inclined in the radial direction; a speed regulating mechanism provided at the output end of the speed increasing gear train; , supported movably in a first direction along the axial direction of the rotating shaft of the rotary body and a second direction along the radial direction of the rotary body, and one end of which is removably connected to the cam portion. and a stopper with the other end facing the speed regulating mechanism so as to be freely engageable and disengageable, and the stopper is moved in the second direction to engage and disengage one end of the cam part, and the other end is engaged with and disengaged from the cam part. The rotational force transmission of the speed increasing wheel train is controlled by engaging and disengaging the speed regulating mechanism, and when overload rotational force is input to the speed increasing wheel train, the overload prevention mechanism is activated and the rotational transmission is interrupted. When the rotating body rotates, the first rotation body of the rotating body rotates.
The stopper is pushed in the first direction by the tapered surface, and the stopper is pushed in the second direction by the second tapered surface, so that one end of the stopper is pushed out from the cam portion. A rotation transmission control device characterized in that the other end of the stopper is disengaged from the speed regulating mechanism to allow rotation of the speed increasing wheel train.
