Abstract: A recoil starter for an engine of a model includes a starter case and a spool rotatably accommodated within the starter case. A rope is wound around the spool and is connected to a handle. A recoil spring is accommodated within the starter case. The inner end of the recoil spring is engaged with a hook of the starter case, and the outer end of the recoil spring is engaged with an outer end portion of the spool. A one-way clutch assuming the form of a prism is fitted into a shaft hole formed in the spool and having a polygonal cross section to thereby be able to rotate unitarily with the spool. A starting shaft is rotatably supported by the starter case. The starting shaft has an extended portion which is inserted through the one-way clutch and penetrates the starter case. An attachment is attached to the extended portion of the starting shaft.
