AI Technical Summary

Problems solved by technology

Therefore, sufficient strength is not obtained for the portion of the rope drum in which the pivot hole is formed, and thus it is necessary to increase the thickness of the rope drum in which the pivot hole is formed.

Embodiment Construction

[0026] Embodiments of the present invention will be described below by way of examples with reference to the accompanying drawings. Such as figure 1 As shown, the wrap-around starter of the illustrated embodiment includes a starter case 1 formed to house main components of the wrap-around starter therein and to cover a side surface portion of the engine. The starter case 1 is provided on its inner side surface with a spool shaft 2 formed coaxially with a crankshaft (not shown) of the engine so as to face the crankshaft. A rope drum 4 having a return rope 3 wound around its outer circumference is rotatably mounted on the drum shaft 2 . Such as figure 2 As shown, the rewinding rope 3 is wound around a drum portion 4 a formed on the outer circumference of the rope drum 4 . One end of the winding rope 3 is pulled out to the outside of the starter housing 1 by forming the opening 5 of the starter housing 1, as image 3 shown. The rope drum 4 is driven rotatably about the drum...

Abstract

A recoil starter is disclosed which enables a ratchet member to be manufactured at a reduced cost and which is capable of obtaining a sufficient strength and reducing a size and weight thereof without increasing a thickness of a rope reel and the like. The ratchet members are mounted on the rope reel so as to engage with a control member that is rotatably attached to a reel shaft with a rotational resistance imparted thereto, so that the ratchet members are turned radially outwardly to engage with a drive pulley, to thereby allow the drive pulley to rotate integrally with the rope reel. The ratchet members are each formed of a rod material having a circular section by bending the material and are each pivotally supported on a side surface of the rope reel.

Description

technical field [0001] The present invention relates to a rewind starter in which the rewind cord is pulled to rotate the cord drum such that the rotation of the cord drum is transferred to a rotating member such as a drive pulley or the like which is connected to the crankshaft of the engine by a ratchet mechanism in order to start the engine. Background technique [0002] In known rewind starters, a rewind rope is wound around a rope drum, the rotation of which is transmitted to a rotating member such as a flywheel magnet or a drive pulley, and the crankshaft rotation of a motor connected to the rotating member is driven by This starts the engine. A ratchet mechanism is arranged between the rope drum and the rotating member. When the rewind cord is pulled to rotate the cord drum in the direction in which the engine is started, the ratchet mechanism engages the rotating member to transmit the rotation to the rotating member. When the engine has been started or when the r...
