Abstract
A chainsaw may include a saw chain; a guide bar, a sprocket, a prime mover, a housing, a sprocket cover, and a guide member. The guide bar, the housing and the sprocket cover may define a chain passage. The guide member may include a first facing surface having an arc shape centered on the rotation axis and a second facing surface having an arc shape centered on a position offset from the rotation axis. When the chainsaw is placed on a horizontal mounting surface and viewed in the direction along the rotation axis, an angle between (i) a straight line connecting the rotation axis and a position where the first facing surface and the second facing surface are connected and (ii) a horizontal plane may be in a range of −10 degrees to 25 degrees.
