PROBLEM TO BE SOLVED: To provide a maintenance-free coupling structure for vibration tester in which coupling state can be sustained with a vibration generator even if the number of screws is decreased. SOLUTION: The coupling structure comprises a pair of coupling members 20, 30 being jointed each other, and a coupler 12 for coupling the pair of coupling members 20-30 each other. The pair of coupling members 20-30 are provided, respectively, with slopes 21a, 31a inclining outward such that the forward end sides approach each other when the members 20, 30 are jointed. The coupler 12 is provided with a recess 12a having a pair of inclining parts 12b being jointed each other across the slopes 21a, 31a of the pair of coupling members 20-30. Under a state where the pair of coupling members 20-30 are jointed each other, the pair of inclining parts 12b of the recess 12a in the coupler 12 are brought into press contact while straddling the inclining parts of the pair of coupling members 20, 30.
