Abstract

A buffering structure is coupled to a treadmill to buffer an action route of a support device. The buffering structure comprises a rockshaft and a buffering cushion. The rockshaft is mounted on the bottom of the support device and pivotally connected to the treadmill. The buffering cushion is connected to the outer surface of the rockshaft. The rockshaft and the buffering cushion are able to buffer the action route of the support device. As a result, the buffering structure of the present invention has simple configuration and low cost, and it is able to adjust the buffer route and not easy to get damaged.

Claims
