In a shaft coupling monitoring apparatus for monitoring a spider joint using outer peripheries of four shafts of a cross shaft as rolling contact surfaces, each of the shafts contains therein a sensor for detecting any damage on the rolling contact surface thereof. Even in a case where the spider joint is incorporated in a driving shaft such as of a rolling mill, the monitoring apparatus may provide high-accuracy and early detection of any damage such as flaking on the rolling contact surface defined on each of the shafts of the cross shaft.
