A reciprocating tool (1) includes a housing (20, 30), a driving source (21), a reciprocation conversion unit (34, 36), —and a vibration reduction mechanism (30). The driving source is accommodated in the” housing. The reciprocation conversion unit (34, 36) 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 (16) movably supported to the housing with a reciprocating motion. The vibration reduction mechanism (70) includes a shaft (72), a weight (71), a support member (73), and a urging portion (74). The shaft i(72)s supported by the housing and extending in a direction perpendicular to directions of the reciprocating motion of the tool bit (41) t and has an axis. The weight (71) is located away from the shaft (72) and is swingable in a swinging direction. The support member (73) swingably supports the weight (71) about the axis of the shaft (72). The urging portion (74) urges the weight (71) toward a prescribed position of the weight in the swinging direction with respect to the housing. |
