1. A driving tool, comprising:
- a piston configured to be driven by compressed air and move in a reciprocating manner;
a tool main body housing the piston;
a driver configured to drive a driven member in a driving direction;
a driver guide attached to a bottom end of the tool main body in the driving direction and configured to guide the driver;
a top cap attached to an upper end of the tool main body in the driving direction and sealing an upper piston chamber; and
an exhaust cover disposed on a lateral side of the tool main body, the exhaust cover including;
a bottom end of the exhaust cover in the driving direction attached to a main body housing of the tool main body via a first fixing screw of the driver guide, the first fixing screw including a first tubular engagement pin integrally disposed at a tip end of the first fixing screw,a top end of the exhaust cover in the driving direction attached to the main body housing via a second fixing screw of the top cap, the second fixing screw including a second tubular engagement pin integrally disposed at a tip end of the second fixing screw, anda lower recess at a lower side of the exhaust cover and an upper recess at an upper side of the exhaust cover, each one of the lower recess and the upper recess being inwardly recessed in a side face area in a planar view of the exhaust cover, the first tubular engagement pin being inserted into and engaging the lower recess at the lower side of the exhaust cover, and the second tubular engagement pin being inserted into and engaging the upper recess at the upper side of the exhaust cover.
