A driving tool (1) includes a housing (10), accumulator chamber (10a), cylinder (11), piston (12A), and counterweight (11B). The piston (12A) divides an inner space formed within the cylinder (11) into a first piston chamber and a second piston chamber. The piston (12A) moves in a first direction directed from the second piston chamber to the first piston chamber by the compressed air supplied into the first piston chamber, thereby performing a driving process to generate a driving force. The counterweight (11B) opposes the cylinder (11) in a direction perpendicular to an axial direction of cylinder (11) and is capable of moving in a second direction opposite to the first direction. |
