A cushion device for an exercise machine, such as treadmill, includes a linkage, a spring and a mount. The linkage is pivoted on a bottom of the exercise machine, and wheel is pivoted on a distal end of the linkage. The mount is fixed to the bottom of the exercise machine, on which the spring is provided to urge the linkage. When user takes exercise on the machine, the vibration from different orientations will transmit to the linkage and make it swing, such that the spring is compressed to absorb the vibration.
