Recoil type starter for internal-combustion engine

Abstract

A recoil type starter device for an internal combustion engine is provided which includes a starting pulley fixed at one end of the engine crank shaft and having a plurality of openings in its circumferential side surface; and a rotatable rope pulley confronting the starting pulley and mounted on a separate fixed shaft, said rope pulley having a pawl to engage any of the openings of the starting pulley to transmit rotational force of the rope pulley to the starting pulley at the start of the engine, a spiral spring to take up the starting rope around the periphery of the rope pulley after start of the engine, a disc fixedly mounted on the shaft of the rope pulley, and a U-shaped wire spring, one end of which is connected to a spring fitting part on the pawl, and the other end of which is frictionally contacted around the circumference of the stationary disc. The spring normally biases the pawl to retracted position, but serves as a drag link to pull the pawl into erected position upon rotation of the rope pulley in a starting direction. A projected member is provided on the side surface of the rope pulley to contact with a tail of the wire spring wound around the stationary disc, when the pawl engages the starting pulley, to reduce the frictional contact force of the wire spring with respect to the stationary disc.
