Abstract: A joint protecting device for a baby stroller, the baby stroller has a pair of guarding housings on the outer surface of two joints on the two lateral sides of the baby stroller. When the baby stroller is collapsed or stretched, each of two upper struts is rotated relatively to a corresponding lower strut on each of the joints and makes one of the two guarding housings rotate about an axle of the joint, thereby the guarding housing obstructs a gap with an angle formed between the joint and the upper strut, and harming by clamping to the baby's fingers can be prevented.
