The present invention improves workability. In a circular saw 10, a protrusion-amount-adjusting mechanism 60 has a lever-biasing spring 80 that biases a fixing nut 74 and an operation lever 78 toward the distal end of a fixing bolt 70 (i.e., in a direction away from a link 66). Therefore, it is poss...

| description | The present invention improves workability. In a circular saw 10, a protrusion-amount-adjusting mechanism 60 has a lever-biasing spring 80 that biases a fixing nut 74 and an operation lever 78 toward the distal end of a fixing bolt 70 (i.e., in a direction away from a link 66). Therefore, it is possible to satisfactorily maintain a state in which the fixing nut 74 is positioned at a non-fixed position. Specifically, it is possible to satisfactorily maintain a state in which the fixing nut 74 and the operation lever 78 are separated from the link 66. This makes it possible for the fixing nut 74 and the operation lever 78 to suppress sliding of the link 66 when a circular saw body 30 is caused to rotate relative to a base 20 in a state in which the circular saw body 30 and the base 20 are unfixed from one another. Therefore, it is possible to improve workability in adjusting the amount of protrusion of a circular saw blade 12. |
