A recoil starter includes: a starter case provided with a reel support shaft; and a ratchet guide rotatably attached to the reel support shaft in a state in which a frictional resistance is applied. The ratchet guide includes: a through hole into which the reel support shaft is insertable; and a locking portion configured to be engaged with the reel support shaft on an inner periphery of the through hole. A movement of the ratchet guide in an axial direction of the reel support shaft is restricted in a state in which the locking portion is engaged with the reel support shaft.

Recoil starter

One aspect of the invention provides a recoil starter including: a reel support shaft; a rope reel that is rotatably mounted on the reel support shaft; a ratchet member that is swingably mounted on the rope reel; a ratchet guide that is rotatably mounted on the reel support shaft with friction resistance. The ratchet guide includes: a guide portion and a swinging-prevention portion. When the rope reel rotates in an engine starting direction, the guide portion pushes out the ratchet member to an outer diameter direction. When the ratchet member does not contact the guide portion, the swinging-prevention portion prevents the ratchet member from swinging to the outer diameter direction.

According to one embodiment, there is provided an anti-vibration structure for a handle of a portable brush cutter, the structure including: a pole; an operation unit provided at a front portion of the pole; an engine provided and a lever device provided at a base portion of the pole; an attachment stay unit fixed to a middle portion of the pole, the attachment stay unit having an accommodation recess at each end thereof; an operation handle having a protrusion protruding from each end thereof; and anti-vibration materials sandwiched between the attachment stay unit and the handle main body in a left-right direction of the pole, so that one side of the anti-vibration material is accommodated in the accommodation recess while the protrusion is inserted in an open-groove formed on the other side of the anti-vibration material.

Anti-vibration structure for a handle of a portable brush cutter

According to one embodiment, there is provided an anti-vibration structure for an operation lever of a portable brush cutter, in which a lever device includes: a main body through which a pole is inserted in an axial direction, the main body including protrusions protruding from both ends in the axial direction; support members provided on the pole to support the both ends of the main body such that the main body is separated from the pole, each support member including a recess; and anti-vibration materials accommodated in the recesses of the support members so as to be sandwiched between the support members and the main body in the axial direction, respectively, each anti-vibration material including a groove to which a respective one of the protrusions of the main body is inserted.

Anti-vibration structure for operation lever of portable brush cutter

A recoil starter includes a base plate that has a bearing portion formed therein and a rotary shaft that is supported by the bearing portion so as to pass through the base plate. A rope reel is rotatably supported at one side of the base plate, and a recoil rope is wound around the rope reel. A recoil spiral spring urges the rope reel to rewind the recoil rope. A damper spring has one end connected to the rotary shaft and the other end connected to the rope reel, and a clutch mechanism is disposed on an end of the rotary shaft at the other side of the base plate. The clutch mechanism transfers a rotational force to an engine.
