Abstract: A working machine may include a pipe including: an outer pipe; an inner pipe inserted in the outer pipe; a pipe holder fixed to the outer pipe; and a stopper disposed inside the outer pipe. The pipe holder includes a wall part. The inner pipe includes a fixing hole having a longitudinal direction in a circumferential direction of an outer circumferential surface of the inner pipe. A rear surface of the fixing hole has a shape extending along a plane orthogonal to a front-rear direction. The stopper includes: an abutting part that abuts the wall part from behind when the inner pipe extends to a maximum length relative to the outer pipe; and a protruding part configured to fit in the fixing hole of the inner pipe. A rear surface of the protruding part has a shape extending along a plane parallel to the rear surface of the fixing hole.

Abstract: A pressure washer disclosed herein may include a pump mechanism configured to pressurize water supplied through a water inlet and pump out the water through a water outlet, an electric motor configured to drive the pump mechanism, and a housing that houses the pump mechanism and the electric motor. An outer surface of the housing most proximate to the electric motor may have a shape that does not allow the pressure washer to stand on its own when the outer surface is used as a placement surface.

Abstract: A chainsaw includes a body housing, an elongated guide bar projecting forward from the body housing, a saw-chain mounted on the periphery of the guide bar for rotation, an electric motor mounted within the body housing for rotating, and a top handle provided on an upper portion of the body housing above the guide bar and extending in a fore-and-aft direction. A plurality of rechargeable battery packs is mounted on the body housing as a source of power supply for the electric motor. The battery packs are mounted to the body housing in such a manner that a center of gravity of the chainsaw observed from the back side is positioned in a two times extent of lateral width of a gripe portion of the top handle at both sides of a vertical centerline of the gripe portion.
