Abstract: A slide hammer puller for car-body sheet metals of a vehicle in the invention has a driven rod, a slide hammer and at least one pulling member. A shank body of the driven rod with a stop portion disposed at a proper position of the shank body corresponding to a hammer face of the slide hammer is extended through the slide hammer and combined with the pulling member at one end of the shank body. Place the pulling member on a dent of a car-body sheet metal and fill hot-melt adhesives between the pulling member and the dent. After the adhesives get dry, strike the slide hammer toward the stop portion to make the driven rod have backward pulling movements to force the pulling member to pull the dent outwardly to its normal smooth position, thereby the dent can be repaired without disassembling interior parts and accessories of a vehicle.
