Abstract
A foldable walker device includes a front frame and a rear frame. The front frame and the rear frame are pivotally connected with each other and can be relatively folded and unfolded. A seat board bridged between the front frame and the rear frame. At least one link, a front end of the link is pivotally connected with the seat board, a rear end of the link is pivotally disposed on the rear frame. When folding the walker device, the rear end of the seat board is lifted, whereby the link pivotally connected with the seat board drives the rear frame to move forward and get closer to the front frame. Under such circumstance, the walker device is folded into a minimum volume so as to minimize the room occupied by the walker device. This facilitates the storage and transfer of the walker device.
