An electric nailing gun in which a piston head is reciprocated with a nailing plunger in a receiving chamber of a cylinder to force air out of the receiving chamber of the cylinder toward a coil of a nail driving mechanism for dissipating heat, which is generated by the coil, during down stroke of the nailing plunger, and to buffer the returning speed of the nailing plunger by compressing air, which exists between the piston head and the receiving chamber of the cylinder, during return stroke of the nailing plunger after each nailing action.
