Abstract: A rotating positioning member of a front wheel of a golf trolley is revealed. A front wheel set is disposed at a front end of a lower frame and including a front wheel base fixed on the lower frame, a front wheel frame, and a front wheel pivotally connected to the front wheel frame. The front wheel base is mounted with an inclined guide slot. A connecting rod is formed on the front wheel frame and pivotally connected to the inclined guide slot. Thus the connecting rod drives the front wheel frame to rotate 90 degrees and the front wheel frame further drives the front wheel to horizontally lean against the lower frame when the front wheel frame is rotated toward the lower frame in the inclined guide slot due to the connecting rod. Thus the golf trolley is easy to fold up for storage.
