Abstract
A cutting tool such as jigsaw generally comprises a main body, a plunger provided for the main body to be reciprocally movable in an axial direction thereof, the plunger being provided with an opening and a cutout axially formed to a portion opposing to the opening, a cutting blade to be mounted to the plunger, and a blade mounting mechanism for mounting the blade to the plunger. The blade mounting mechanism comprises a support member inserted into the opening of the plunger and provided with an engaging groove formed along a direction of mounting the blade, a ring member disposed to outer peripheral surfaces of the support member and the plunger, the ring member being formed with a tapered portion at an inner peripheral surface thereof opposing to the cutout of the plunger, and an elastic member for urging the ring member in a direction that a diameter of the tapered portion of the ring member reduces, thereby fastening the blade by the tapered portion of the ring member and the engaging groove of the support member.
