Abstract: A crank pulley for a recoil starter which integrally comprising a plate body, a leg portion perpendicular to the plate body and an impact surface formed on the leg portion.

Abstract: A crank pulley for a recoil starter is disclosed, in which a touching nail 12 is integrally provided in a recoil starter side by a press forming process in a shape of a protrusion. The touching nail has an L shape by bending in a reverse rotation direction, and a bending top face forms a contact dog. A corner of the touching part of at a top of the touching nail, and an outer corner part at the bending part of the touching nail, are formed into a curved or chamfered shape, and the dog is capable of being moved to the engine side, during a starting operation.

Abstract: A recoil starter comprises a reel 7 rotatably supported by a case 2, a slant first cam 14 disposed on the reel 7 and facing an engine side, and a dog 20 rotatably and axially movably supported on an axis coaxial with the reel 7. The dog 20 is provided with an engagement claw 26 engageable with an engagement portion 28 on the engine side, and a first cam follower 23 engageable with the first cam 14. The recoil starter further comprises a retainer 31 mounted on the case 3, the retainer 31 being engageable with the dog 20 and capable of braking rotation of the dog 20. The recoil starter further comprises a projection 15 projecting from the reel 7 and engageable with the dog 20 when the reel 7 starts rotation. The reel 7 is provided with a slant cam 18 facing away from the engine side. The dog 20 is provided with a second cam follower 24 engageable with the second cam 18.

Abstract: A recoil starter for starting a small-size engine including a starter case, a center shaft, a reel, a rope groove, a rope, a recoil spring, and a dog. In the recoil starter, a circular boss portion is provided on and projected from the central portion of the reel, an engaging opening of a crank pulley is disposed outside the boss portion, an engaging wall having a flat engaging surface is provided on the reel disposed outside the crank pulley. When the dog is engaged with the crank pulley, the leading of the dog is projected externally of the engaging opening to come into engagement with the engaging wall, so that one end of the dog is supported by the engaging wall while the other end thereof is supported by the inner surface of a dog storage hole.
