Abstract
The present invention relates to a wheel mounting assembly for a walker apparatus. The assembly has a pivotable wheel fork and a frame portion. A shaft is coupled to a first one of the wheel fork and the frame portion and is rotatably connected to a second one of the wheel fork and the frame portion. A bearing is interposed between the second one of the wheel fork and the frame portion and the shaft. The assembly has an alignment member with a first portion shaped to extend around and abut with the shaft. The alignment member has a resilient second portion configured to slidably engage with the second one of the wheel fork and the frame portion. The second portion of the alignment member is spaced-apart from the bearing. The alignment member thereby rotatably aligns and further supports pivoting of the wheel fork about the shaft.
