A hammer cage, adapted for use in an impact tool that has a pin and a hammer swingable on the pin, includes: first and second walls, and first and second connecting walls independently interconnecting the first and second walls and cooperating with the first and second walls to define an impact space for receiving the hammer; and a first restricting structure having a pin hole member that extends through the first wall and that is adapted for extension of the pin, and a first restricting protrusion that protrudes from the second connecting wall toward the first connecting wall and that is adapted for restricting swing motion of the hammer on the first pin in the impact space.
