<P>PROBLEM TO BE SOLVED: To provide a hammering tool capable of performing a stable hammering operation by eliminating a hammering failure during a low temperature. <P>SOLUTION: This hammering tool 1 includes a piston 14 reciprocating in a cylinder 17 by driving force of a motor 31, and a striker 19 which is hammered via pressure variation of an air chamber 15 in the cylinder 17 by the piston 14 to transmit the hammering force to a distal end tool. In the hammering tool 1, a space in which the piston 14 and the striker 19 are stored is constituted as a sealed space by being shut off from outside air. The hammering tool 1 includes a pressure adjuster (60) for allowing air to pass from outside air to the sealed space. The pressure adjuster is a valve 60 for allowing air to pass in only one direction when a pressure difference of a prescribed value or more is generated, such as a rubber one-way valve, for example. <P>COPYRIGHT: (C)2012,JPO&INPIT |
