A golf bag cart front wheel foldable device includes a fixed mount, a movable mount and a front wheel frame. The fixed mount has one end connected to the bottom tube of the cart frame and the other end provided with a fitted end. The fitted end is in pinned connection with a buckle at its one side. The movable mount is capable of being seized by the buckle and is joined fixedly to the fixed mount by a hinge. The movable mount has one end provided with a fitted end which is physically in harmony with the fixed mount. The front wheel frame has a top end connected fixedly to the movable mount, while its bottom end is joined to the front wheel. Through loosening of the buckle, the movable mount is not seized, which enables the movable mount and the front wheel frame to rotate with respect to the hinge, and the front wheel is then leveled for folding purposes, to achieve great handiness in maneuvering.
