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： The invention relates to a power transmission mechanism between an engine starting device and an engine. A side surface shape of a lever-shaped engaging and disengaging member (107) in a side facing to a ratchet wheel (120) of a rotation driven portion is formed in a concave shape concaved in a direction away from the wheel (120). The lever-shaped engaging and disengaging member (107) is engaged with and disengaged from a centrifugal clutch mechanism of the engine engaging with and disengaging from the ratchet wheel (120). A first engaging and disengaging lever (141) is engaged with the ratchet wheel (120), a sufficient force to start the engine is accumulated in a force accumulating power spring (131), thereafter the engagement of the first engaging and disengaging member (141) is disconnected by a manual operation, and the ratchet wheel (120) is rapidly rotated by releasing the accumulated force in the force accumulating power spring (131). When the ratchet wheel (120) starts rotating at this time, a stop position of the lever-shaped engaging and disengaging member (107) is not determined, and it is often the case that the lever-shaped engaging and disengaging member (107) and the rapidly rotating ratchet wheel (120) are not originally in the engaged state. As a result, leading ends of the engagement surfaces come into collision with each other so as to be broken, and it is hard to start the engine. However, the lever-shaped engaging and disengaging member (107) is not broken on the basis of the shape and the structure peculiar to the invention, and it is possible to securely start the engine regardless of the stop position thereof and an abrasion of the first engaging and disengaging lever (141).

摘要： Through holes formed on an atomization pipe can prevent fuel adhering on inner walls of the through holes from escaping. In addition, when fuel adhering on an inner circumferential surface of the atomization pipe flows toward a downstream side, the fuel enters the through holes. Thus, the fuel can be confined therein. Furthermore, an absorbing member can absorb the fuel that has adhered to a downstream inner wall of the atomization pipe and flows toward the downstream side. Moreover, a periphery of the intake passage hole of a gasket protrudes from the inner wall, so that flow of the fuel that the absorbing member fails to absorb toward the downstream side can be blocked. Accordingly, a rapid increase in the amount of fuel flowing into the engine body can be reliably prevented. Therefore, fluctuation in the number of revolutions of the engine can be sufficiently restrained.
