Abstract: 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.

Abstract: 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.
