In the present automatic strap retracting mechanism for wheel restraint devices, the wheel restraint device comprises a shell, and a reel is rotatably connected inside the shell. A ratchet is fixed to the reel, and the tooth surface of the ratchet consists of a locating surface and a guiding surface. A locking piece is also hinged to the shell, and the locking piece has a pawl. The automatic strap retracting mechanism comprises a coil spring which is connected to the reel and can drive the reel to rotate in the direction of strap retracting and wind in and retract the fastening strap. The locking piece also comprises a locking rod. When the pawl detaches from the locating surface and the fastening strap is pulled out, the locking piece can swing to allow the locking rod to abut on the guiding surface.
