Both ends of the support shaft 2 are caulked and fixed in between, and a pinion seat 4 is interposed between the respective number wheels of a plurality of character wheels 3 rotatably arranged on the support shaft 2 and provided on the pinion seat 4. By the pinion 5 rotatably attached to the pinion shaft 4a, the rotation of the lower digit number wheel is sequentially transmitted to the upper digit number wheel, and the support shaft 2 of each pinion seat 4 is fitted to the outer circumference of the cylindrical portion 4b. The central cylindrical portion 3a of each numeral wheel is fitted and held rotatably. A part (not shown) of the pinion seat 4 is engaged with the frame 1 and its rotation is restricted. A drive gear 6 is connected to the numeral wheel 3 of the lowest digit so as to rotate together. The numeral wheel 3, the pinion seat 4, and the drive gear 6 supported by the support shaft 2 are restricted from moving in the axial direction of the support shaft 2 by stoppers 7a and 7b such as E-rings on both sides thereof. In addition,
The stopper 7a on the upper girder side may be replaced by a spring compressed between the stopper 7a and the supporting portion 1a of the frame 1.

減されてしまうという欠点があった。However, in the above-mentioned conventional one, the cylindrical portion 4b of the pinion seat 4 and the numeral wheel 3 rotatably fitted to the outer periphery thereof.
The central cylindrical portion 3a of is fitted into a surface contact. Therefore, the rotation resistance of the numeral wheel 3 with respect to the cylindrical portion 4b of the pinion seat 4 is large, and the rotation of the lowest numeral wheel 3 driven by the drive gear 6 is transmitted to the upper numeral wheel 3 via the pinion 5. In addition to requiring a large force to do so, a large load is applied to each part, and in order to smoothly transmit rotation by the pinion 5, the pinion seat 4 is provided with a long cylindrical portion 4b to prevent the pinion seat 4 from collapsing. There was a drawback that the effect was reduced by half.
