Abstract

In a recoil starter that starts an engine, the recoil starter rotating a drive shaft of the engine using rotation force of a reel through a recoil rope wound around the reel, by the recoil rope being pulled, a ratchet claw is provided on the reel, the ratchet claw pivoting in a radial direction of the reel with rotation of the reel by the recoil rope and then engaging with a pulley provided on the drive shaft, a guide member is provided around a reel shaft, the guide member covering the ratchet claw, the reel shaft being a rotation shaft of the reel, and a rib is provided on the guide member, the rib abutting on the ratchet claw.

First claim

What is claimed is:

1. A recoil starter that starts an engine, the recoil starter rotating a drive shaft of the engine using rotation force of a reel through a recoil rope wound around the reel, by the recoil rope being pulled, wherein:
a ratchet claw is provided on the reel, the ratchet claw pivoting in a radial direction of the reel with rotation of the reel by the recoil rope and then engaging with a pulley provided on the drive shaft;
a guide member is provided around a reel shaft, the guide member covering the ratchet claw, the reel shaft being a rotation shaft of the reel;
a rib is provided on the guide member, the rib abutting on the ratchet claw;
the reel has a top surface that is positioned on a side of the engine;
a containing portion in which the ratchet claw is contained is provided in the reel;
the containing portion has a concave shape that is depressed in a shaft direction of the reel shaft toward a side opposite to the engine from the top surface;
a containing surface that is a flat surface provided so as to stand from the top surface is formed on the containing portion;
an engagement surface that is a flat surface is provided on the ratchet claw; and
in a case where the recoil rope is not pulled and where the reel is in a stationary state without rotating, a whole of the engagement surface abuts on the containing surface and the rib abuts on the ratchet claw, so that the ratchet claw is fixed by being sandwiched between the containing surface and the rib.

2. The recoil starter according to claim 1 , wherein the rib releases the ratchet claw that moves in a circumferential direction of the guide member, with the rotation of the reel by the recoil rope being pulled.

3. The recoil starter according to claim 1 , wherein:
a protrusion portion is provided on the ratchet claw;
a guide groove is provided on the guide member, the protrusion portion engaging with the guide groove;
the guide member maintains a stationary state even when the recoil rope is pulled;
the protrusion portion moves along the guide groove, with the rotation of the reel by the recoil rope being pulled; and
the guide member has such a disk shape that the guide member covers the protrusion portion no matter what position in the guide groove the protrusion portion moves to.
