Abstract

A starting apparatus for small-sized engines which is composed of a combination of a cell motor and a recoil starter is disclosed. A rotor gear is loosely fitted on a support shaft of the recoil starter on which a reel is supported, and the rotor gear is also meshed with a pinion gear constituting a reduction gear of the cell motor which is disposed side by side with the recoil starter. When the recoil starter is used, the rotor gear is rotated through the reel. When either the cell motor or the recoil starter is actuated, the rotor gear is rotated only in the forward direction by the function of a one-way clutch (including a ratchet type one-way clutch), whereas, when the reel or the pinion gear rotates reversely, they race but do not cause the rotor gear to rotate by the function of the one-way clutches. The forward rotation of the rotor gear is used to drive a pulley which is secured to the crankshaft, thus starting the engine. Accordingly, the engine is normally started using the cell motor, and when the battery is dead and it is therefore difficult to start the engine with the cell motor, the engine can be started using the recoil starter. Therefore, it is possible to start the engine without worrying about the battery even after the machine has been left to stand for a certain period of time.
