    摘要: Provided is a portable power working machine that is designed to suppress mixing of dust into air sucked into an air intake system of an air-cooled internal combustion engine mounted as a driving power source for working units, for example, and reliably prevent an air cleaner provided to the air intake system of the internal combustion engine from being clogged with dust, and thus eliminate the necessity of frequently cleaning the air cleaner. An air intake port of an air intake passage is arranged on the opposite side of the internal combustion engine with respect to a straightening passage formed around a cooling fan, so that, of the air released from a discharge port of the straightening passage, at least part of air released toward the opposite side of the internal combustion engine with respect to the straightening passage is taken into the air intake passage via the air intake port.

    摘要: A protection cover 4 covering a part of a cutting blade 3 includes a cylindrical attachment part 45 extending around the central axis X of the cutting blade 3. The attachment part 45 is turnably attached to the cutting machine body. An elastic member 53 is disposed on the outer circumferential surface of the attachment part 45. A fastening tool 54 for fastening the elastic member 53 to the outer circumferential surface of the attachment part 45 is kept from turning about the central axis X with respect to the cutting machine body.

    摘要: The hand-held cutter 1 includes: a cutting blade 3 which is configured to rotate about a rotation shaft 23a to cut a target; a cutter body 2 which rotatably supports the cutting blade 3; a protection cover 4 which covers a portion of the cutting blade 3 and is rotatable about the rotation shaft 23a; a pressing mechanism 5 which is configured to move toward the protection cover 4 to press a guide plate 44 onto a support plate 26 so as to impose and maintain restrictions on rotation of the protection cover 4; and a torsion coil spring 7 exerting a biasing force to move the pressing mechanism 5 toward the protection cover 4. The hand-held cutter 1 is configured such that moving the pressing mechanism 5, against the biasing force of the torsion coil spring 7, away from the protection cover 4 removes restrictions on the rotation of the protection cover 4.

    摘要: An object of the present invention is to increase the durability of an engine by separating dust particles sufficiently with as few components as possible, and to extend the maintenance cycle of an air filter.
    A cyclone separator 11 having a circular cross section is arranged upstream of an air filter 18. An introduction passage 12 extends from a branch air inlet 10, which is provided at a position displaced from a main passage 9, to the cyclone separator 11. A margin space 13 where at least part of air introduced in the introduction passage 12 flows is formed in the introduction passage 12 before the cyclone separator 11. A swirl flow occurring in the cyclone separator 11 starts at this margin space 13.
