Abstract
An up and down restoration treading leisure exercise apparatus comprises a rack body, a rear wheel shaft gear, a braking component, an unidirectional flywheel, a spindle component, a chain wheel, a driving belt and a transmission belt. The spindle component is disposed to the rack body. The shaft core of the spindle component is provided for mounting the unidirectional flywheel and the chain wheel. The driving belt is circularly disposed to the unidirectional flywheel to provide unidirectional transmission force. When a user downwardly treads the braking component, the branch bar of the braking component will pull the driving belt and enable the unidirectional flywheel and the chain wheel at the same axis to synchronously rotate. The chain wheel drives the rear wheel shaft gear and the rear wheel through the transmission belt.
