<P>PROBLEM TO BE SOLVED: To make a machine long direction compact, in a reciprocating tool such as a reciprocating saw, converting a rotation output of an electric motor into the reciprocating motion of an output rod through a crank mechanism and outputting it. <P>SOLUTION: In this reciprocating tool, the electric motor 10 uses an outer rotor motor having low-speed rotation and capable of outputting high torque as a drive source. An output shaft 14 of the electric motor 10 is coaxially provided with a crank disk 21 of the crank mechanism 20, and the machine long direction is made compact by making the reciprocating tool a direct drive type in which a conventional reduction gear train is eliminated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
