Abstract

Providing a reciprocating tool capable of reducing vibrations generated during operations and improving work performance and processing precision. A reciprocating tool includes a transmission gear partand a counter weight part. The transmission gear partincludes a bevel gearand a weightA. The bevel gearis rotatable in a first direction about an axis B by receiving a drive force of a motor. The weightA is rotatable in a second direction opposite to the first direction about the axis B by receiving the drive force of the motor. A center of gravityG of the transmission gear partand a center of gravityG of the counter weight partare separated farthest from a blade mounting partwhen the blade mounting partis positioned in a rearward position. The center of gravityG of the transmission gear partand the center of gravityG of the counter weight partare closest to the blade mounting partwhen the blade mounting partis positioned in a forward position.
