Abstract

The present invention improves workability. In a circular saw, a protrusion-amount-adjusting mechanism includes a lever-biasing spring, and the lever-biasing spring energizes a fixing nut and an operation lever toward a tip end side (i.e., the direction away from a link) of a fixing bolt. Thus, the state of the fixing nut configured at the non-fixed position may be retained well. That is, the separation state of the fixing nut and the operation lever from the link may be retained well. In this way, in the fixing release state of the circular saw body and the base, when the circular saw body is rotated relative to the base, the fixing nut and the operation lever may be prevented from sliding on the link. Thus, workability when adjusting the protrusion amount of the circular saw blade may be improved.
