<P>PROBLEM TO BE SOLVED: To provide a shaft-end construction capable of restraining speed fluctuation of a driven shaft caused by misalignment of a rotational center, without causing the above-mentioned problems of an Oldham coupling. <P>SOLUTION: A coupling gear 52Y functioning as the driven shaft is constituted as follows: of two pawls 53Y that are projecting portions projected from the end face of the coupling gear 52Y, length L2 in a rotational direction of a pawl rotational orbit is made longer than length L1 in a normal direction. This further moves a position where the pawls 53Y of the coupling gear 52Y contact with pawls of a driving shaft that are not illustrated toward the shaft outer peripheral side. By further moving the contact position of the both pawls to the shaft outer peripheral side, a rotational angle of the coupling gear 52Y is brought close to the driving shaft to restrain the rotational speed fluctuation. <P>COPYRIGHT: (C)2004,JPO |
