A shot-peening device capable of improving the fatigue strength of a workpiece by applying compressive residual stress to the inside of the workpiece has a hollow housing and a vibration device for vibrating the housing. The housing stores a workpiece and shot therein. The vibration device vibrates the housing with the workpiece and the shot stored therein. Accordingly, the fatigue strength of the workpiece is improved by applying compressive residual stress to the inside of the workpiece.
