パー爪穴６ａに入りピニオン歯車４の位置を固定する。It has a pinion gear 4 that freely slides in the axial direction on a rotating shaft 3 perpendicular to the rotation center of a plurality of face gears 1 formed on the same plane axis. This pinion gear rotates integrally with the rotating shaft 3 by rotating shaft serrations m3a (D force/groove or spline is also possible). By moving the pinion gear shifter knob 5a in the Xb direction, the shifter 5 pushes the pinion gear 4 in the X1 direction, changing the meshing from the outer face gear to the inner face gear and changing gears. The meshing change from the inner face gear to the outer face gear is similarly performed by operating the shifter 5 in the Xa direction. The rotational driving force of the face gear l is transmitted to the pinion gear 4, which rotates the rotating shaft 3 and transmits the driving force from the pinion gear 10 at the other end to the face gear 11 at the other end. The power may be transmitted from the other end face gear 11 to the face gear 1. Further, the combination of the other end gear 10111 may be a combination with the multi-stage face gear on the left in the figure, or a combination with a bevel gear. Reference numerals 2 and 12 indicate bearings for the gear shafts, which are connected to the chassis of the device main body (not shown) and support the face gear and the rotating shaft in a freely rotatable manner. 6 and 6a indicate the shifter stopper and stopper critical, and the claws (not shown) are

し■とＬ２の長さの関係は任意である。FIG. 9 shows a front view of the face gear and a side view of the pinion gear, and shows an example of means for enabling the face gear 1 and the pinion gear 4 to be remeshed. The distance between the tooth 1z of the outer face gear and the tooth 1zz of the inner face gear is Ll.
Let the tooth width of the pinion gear be L2. When the pinion gear that was meshing with the outer face gear is remeshed with the inner gear, the number of teeth differs between the outer and inner gears due to the difference in diameter, and the teeth do not match in phase. To match the phase of this gear, set LL > L2, move the pinion gear 4 radially to the range Ll, disengage it from the face gear, and rotate the face gear 1 to a position that matches the phase of the inner tooth 1yy. Blend each one together. Further, the phases of the troughs of the teeth of the outer and inner gears are matched for every integer ratio of the number of teeth, and the pinion gear 4 is remeshed at that position. In this case, the relationship between the length and the length of L2 is arbitrary.
