Abstract
A shaft coupling includes an annular plate having a proper axial flexibility. The annular plate is formed with mounting holes. A first group of coupled portions are fixedly connected to an input shaft, whereas a second group of coupled portions are fixedly connected to an output shaft. The first and second groups of coupled portions are coupled with each other through the annular plate placed therebetween, so that the first and second groups of coupled portions circumferentially alternate with each other. The annular plate has coupling arm portions each extending between two adjacent mounting holes to absorb axial vibrations. A radial width of the coupling arm portion is dimensioned to be narrower than a radial width of a peripheral region of each of the mounting holes. A length of the coupling arm portion is dimensioned to be longer than a distance between the two adjacent mounting holes.
