摘要： A muffler of a work machine in the form of an engine blower includes: a muffler body; and a diffuser that covers an exhaust outlet of exhaust gas provided on the muffler body. The diffuser has a diffusion space to diffuse the exhaust gas and an exhaust surface on which a plurality of exhaust circular holes are provided to exhaust the exhaust gas to an outside. An opening ratio provided by the exhaust holes of the exhaust surface is gradually increased from a portion corresponding to the exhaust opening toward an outer periphery of the exhaust surface.

摘要： The invention relates to an auto tensioner of a chain saw. A spiral guide groove (16) of the disk (15) engages with a protrusion 10a of a slider piece (10) and the slider piece (10) is slidably stored in a guide portion (9) formed in a chain cover (2) via a spring (14). A tensioner (11) comprising a protrusion (11) engaged with a guide bar is slidably stored in the slider piece 10 via a coin spring (12). The protrusion (10a) contacts an outer circumference face of the spiral guide groove on a diameter passing through a rotating center of the disk, and an unshown nut for engaging with a stud bolt 6 provided on an engine cover side is attached on the rotating center of the disk (15). A rotation of the disk enables to fix the chain cover (2) and move the guide bar.

摘要： A cooling fan includes: a hub; a plurality of cooling vanes provided along an outer circumference of the hub; and an annular connector for connecting the cooling vanes. The hub is provided with a through hole that axially penetrates the hub. A first cover on a case for covering an outward side of the cooling fan is provided with a first outer-air intake. A second cover for partitioning between the cooling fan and a crankcase and for covering an inward side of the cooling fan is provided with a second outer-air intake. With this arrangement, even when one outer-air intake (for instance, the first outer-air intake) adjacent to where the cooling vanes are provided is clogged by a large amount of dust generated during operations, the cooling vanes can breathe from the non-clogged other outer-air intake (for instance, the second outer-air intake) through the through hole, thereby restraining reduction in air flow.

摘要： Since a throttle hole for narrowing a scavenging passage is provided on a partition for closing the scavenging passage, the throttle hole of a desired size can be drilled at a desired location on the partition after preparing the scavenging cover having no throttle hole on the partition. Accordingly, the size and location of the throttle hole can be easily changed in conducting a test for finding the most appropriate size and location of the throttle hole, so that the most appropriate size and location of the throttle hole can be easily found.

摘要： An engine blower includes a centrifugal blower having a volute case in which a fan is accommodated; an engine attached to the centrifugal blower for driving the fan; a carburetor mounted to the engine via an insulator; and a lead wire that establishes conduction between the engine and the carburetor. The electrical potential difference between the engine and the carburetor can be eliminated, which prevents electrostatic discharge between the engine and the carburetor even when static electricity is built up in a volute case or a ventilation tube. Accordingly, ignition timing can be prevented from shifting due to an influence on an electrical circuit by the discharge within an ignition unit.

摘要： A chain saw includes a body in which an engine for driving a saw chain is laterally housed; a top handle provided above the body; and a muffler arranged below the engine, in which an exhaust outlet for discharging exhaust from the front side of the body to the outside opens forward from the front side of the body. Accordingly, not only the exhaust can be discharged forward from the front side of the body, but also the exhaust sound can be propagated forward so that less exhaust sound is heard by the operator, thereby improving the work environment.
