ABSTRACT:
A spiral spring type starter apparatus for an internal combustion engine is disclosed. The apparatus includes a power accumulator mechanism having a spiral spring with its one end fixed to a starter shaft and its other end fixed to a power accumulator box, a ratchet device provided respectively on the starter shaft side and on the power accumulator box side of the power accumulator mechanism for maintaining a power accumulated condition in the spiral spring and also for enabling power to be input to the power accumulator box and power to be output from the starter shaft, a centrifugal type ratchet mechanism interposed between the starter shaft and a crank shaft of the engine, a motor adapted to be fed with electric power from a generator through a control circuit after starting of the engine, and a power transmission device for transmitting output power from the motor to the power accumulator box. The motor and battery can be reduced in size. The electric control circuit for operation and stoppage of the motor for driving the spring power accumulating chamber is simple, and assembly of the starter is easy.
