Driving tool

A driving tool comprising:

• a plunger movable in a first direction along a direction in which a fastener is launched;
• an urging member that is extendable and contractible in the first direction and serves as a drive source of the plunger;
• and
• guide rails configured to guide movement of the plunger in the first direction,
• wherein the guide rails extend along the first direction of the urging member and are disposed on both sides sandwiching the urging member,
• wherein a front-rear direction extends perpendicular to the first direction, and each guide rail includes a center in the front-rear direction corresponding to a center with respect to the front-rear direction, and
• the guide rails are arranged such that a virtual line connecting the centers in the front-rear direction of the guide rails on the both sides of the urging member is deviated from a central axis of the urging member in a plan view of the urging member as viewed from the first direction.
