Claims

[Claims for Utility Model Registration] A shaft member 1 that holds a pinion cutter 24 at its tip and makes linear reciprocating motion in the axial direction and is rotatable about the axial center; pinion cutter 2
A casing 19 is rotatably driven at a speed to perform the generating motion of 4, and in which the shaft member 1 is rotatably fitted. an arm member 13 that is rotatably held around an axis and extends outward in the rotational radial direction; a gear 15 that is provided on the shaft member 1 and has a common rotation axis with the shaft member 1; A rack gear 14 supported by the casing 19 is provided at the extending end of the arm member 13 so as to be capable of reciprocating movement in a direction in which the gear 15 meshes with the shaft member 1 and rotates the shaft member 1 around its axis. It has a wedge surface 32 whose inclination angle can be variably adjusted with respect to the axis of the shaft member 1, and the wedge surface 32 is brought into contact with a part of the rack-type gear 14 while the shaft member 1 is rotated. Wedge means 12, 1 that moves in a linear reciprocating manner together with the arm member 13 following the linear reciprocating movement.
2'; and the wedge means 12 for the rack gear 14.
