Abstract

A driver which strikes a fastener to drive it into a target object has a cylinder and a driver blade which is reciprocably housed in the cylinder and is driven to reciprocate by pressure of fluid supplied into the cylinder to strike the fastener, and the driver blade is made up of a shaft part and a piston provided at one end of the shaft part and a damping member is incorporated in the shaft part.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese Patent Application No. 2012-146217 filed on Jun. 29, 2012, the contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a driver for driving fasteners such as nails or screws into a target object such as wood or drywall. Background technique [0004] Drivers that strike a fastener with a reciprocating driver blade to drive it into wood or drywall are well known. Japanese Patent No. 3211225 describes a driver using compressed air as a power source for the driver blades. [0005] A driver described in Japanese Patent No. 3211225 is provided with an air cylinder including a driver blade. The driver blade is pushed down by the pressure of compressed air supplied to the cylinder and strikes the head of the fastener. Specifically, the driver blade is pushed down by the pressure of compressed air supplied to the space (u...
