Abstract
A nailer includes a case part with hollow shape and a piston part. The case part includes a cylinder. The piston part defines a pressure chamber inside the case part and strikes a fastener by moving to a lower side due to a pressure of a gas in the pressure chamber. The piston part includes: a base member including a sidewall; an X-ring attached to the base member to be interposed between the sidewall and the cylinder; and an O-ring interposed between the sidewall and the cylinder and attached at a position different from the X-ring in an up-down direction. The X-ring includes a first base part and a lip part standing from the first base part and contacting the cylinder. The O-ring includes a second base part and does not include a lip part standing from the second base part.
