This application provides a damping mechanism, a hinge apparatus, and a foldable electronic device. The damping mechanism includes a fixed base, a damping swing arm, a rolling body, and a push-pressing apparatus. The damping swing arm is rotatably disposed on the fixed base by using a damping member, a first concave portion, a protrusion, and a second concave portion are disposed on a side wall of the damping member, and the protrusion has a guide surface inclined relative to an axis. When the push-pressing apparatus squeezes the guide surface of the protrusion by using the rolling body, the guide surface can enhance effect of a push-pressing force of the push-pressing apparatus, so that the damping member is subject to greater pressure, and torque damping is increased when the damping swing arm rotates. Therefore, in same space, the damping mechanism can provide a greater damping force. This ensures that the damping swing arm can stably hover at any rotation position and improves comfortableness of rotating the damping swing arm.
