A reciprocating tool includes a motor, a driving mechanism, a body housing, a movable part, and a vibration control mechanism. The driving mechanism includes a reciprocating member configured to reciprocate in a first direction. The movable part is connected to the body housing via a first elastic member and a second elastic member to be relatively movable in the first direction. The vibration control mechanism includes at least one weight configured to move in a direction opposite to the reciprocating member. The center of gravity of the at least one weight is offset from the driving axis in a second direction. In the second direction, the first elastic member is closer to the center of gravity than the second elastic member. A load of the first elastic member when the movable part is placed in a closer position is smaller than a load of the second elastic member.

Reciprocating tool

A switch device for a power tool includes a switch case and a switch lever. The switch lever extends outwardly from within the switch case. The switch lever has a rotative portion rotatably supported by a support portion of the switch case. A waterproofing member is disposed between the rotative portion and the support portion and provides a waterproof seal therebetween.
