Reciprocating tool

A reciprocating tool comprising:

• a housing;
• a driving source accommodated in the housing;
• a reciprocation conversion unit supported by the housing and configured to convert a driving force of the driving source into a reciprocating motion for providing a tool bit movably supported to the housing with a reciprocating motion;
• a vibration reduction mechanism comprising:
• a shaft supported by the housing and extending in a direction perpendicular to directions of the reciprocating motion of the tool bit and having an axis;
• and
• a weight located away from the shaft and swingable in a swinging direction;
• a support member swingably supporting the weight about the axis of the shaft;
• and
• a urging portion urging the weight toward a prescribed position of the weight in the swinging direction with respect to the housing;
• and
• a swing-range restricting portion capable of restricting a swing angle range of the weight in a swing direction of the weight.

• and
• a urging portion urging the weight toward a prescribed position of the weight in the swinging direction with respect to the housing,
• wherein the urging portion includes a pair of leaf springs each having a restricted part, a contact part, and a deformable part, the restricted part being fixed to the housing, motion-restricted by the housing and having one end portion connected to the deformable part, the contact part being capable of contacting the weight, and the deformable part being interposed between the restricted part and the contact part, and
• wherein the deformable part includes a small-width region having a width, in an axial direction of the shaft, smaller than that of the one end portion of the restricted part.
