A reciprocating tool includes a housing, a driving source, a reciprocation conversion unit, and a vibration reduction mechanism. The driving source is accommodated in the housing. The reciprocation conversion unit is supported by the housing and is configured to convert a driving force of the driving source into a reciprocating motion for providing a tool bit movably supported to the housing witha reciprocating motion. The vibration reduction mechanism includes a shaft, a weight, a support member, and a urging portion. The shaft is supported by the housing and extending in a direction perpendicular to directions of the reciprocating motion of the tool bit and has an axis. The weight is located away from the shaft and is swingable in a swinging direction. The support member swingably supports the weight about the axis of the shaft. The urging portion urges the weight toward a prescribed position of the weight in the swinging direction with respect to the housing.
