Abstract: A portable cutter has a base member, a main body, a cutting blade, a protection member, a dust collection member, and a guide member. The base member moves on a workpiece, the base member having a shaft provided in proximity to one end thereof. The main body is coupled to the base member. A posture of the main body with respect to the base member is changeable. The cutting blade is attached to the main body and driven to cut the workpiece. The cutting blade has an outer periphery. The protection member covers a part of the outer periphery of the cutting blade. The dust collection member has an inlet provided in proximity to the outer periphery of the cutting blade for drawing and collecting dust. The guide member is pivotably supported to the shaft of the base member for guiding the dust to the opening of the dust collection member.

Abstract: A holding fixture can securely fix a work implement, and does not become an obstacle when the work implement is carried or in used. The holding fixture 20 is provided with a flexible wire 21 which is attached in a housing hole 15 and movable in a length direction of the housing hole 15, wherein the housing hole 15 is a thin and long curved hole extending from the battery mounting unit 12 to the grip 11. One end of the wire 21 is separated from the electric torch 10, and a L-shaped hook 22 is anchored to said one end of the wire 21 as a hooking tool for fixing the electric torch 10 by its own weight. The worker pulls the hook 22 (wire 21) out of the housing hole 15 and can use the hook 22 for fixing the electric torch 10.

Abstract: A power tool includes: a power tool main body; a handle holder protruding from the power tool main body; a handle extending in a protruding direction of the handle holder and having an arm portion engaging the handle holder; and an elastic body carried between the power tool main body and the handle. The handle holder has a spherical convex outer circumferential face. The arm portion surrounds the handle holder and has a spherical concave inner circumferential face. The convex outer circumferential face of the handle holder is inserted and fitted into the concave inner circumferential face. The elastic body is carried between the power tool main body and the handle around the outer circumference of the handle holder in a radial direction vertical to a protruding-direction central axis of the handle holder.
