ABSTRACT:
A recoil starter composed of: a rotating reel which fits loosely around a supporting shaft in a housing, a cylindrical hub portion of the reel having a spiral spline which is integrally formed on its inner periphery; a clutch cylinder which is loosely inserted into the cylindrical hub portion and carries a spline groove for such engagement with the hub spline whereby relative rotation of the reel hub and clutch cylinder causes axial projection and retraction of the clutch cylinder; and clutch projections which are provided at the free end of the clutch cylinder such as to project and engage recesses integral with a flywheel on the associated engine. Inside the clutch cylinder at its bottom a stepped portion is provided where an axial notch is formed. A coiled spring is loosely fitted around the supporting shaft, and compressed and frictionally restrained by a fixed washer against free rotation which frictional resistance is applied to the clutch cylinder either directly via a hooked end of the coiled spring loosely inserted into the notch inside the clutch cylinder or indirectly through a collar keyed to the notch. In order to prevent the clutch cylinder from projecting when the engine has started, the axial notch includes a lateral extension to resemble an L, the extension projecting peripherally with respect to the axial direction.
